IN AR Y 3 CS4953xx Data Sheet 32-bit Audio Decoder DSP Family 1. Documentation Strategy The CS4953xx Datasheet describes the CS4953xx family of multichannel audio decoders. This document should be used in conjunction with the following documents when evaluating or designing a system around the CS4953xx family of processors. Table 1. CS4953xx Related Documentation Document Name CS4953xx Datasheet CS4953xx Hardware User's Manual This document Includes detailed system design information including Typical Connection Diagrams, Boot-Procedures, Pin Descriptions, Etc. Includes detailed firmware design information including signal processing flow diagrams and control API information Description AN288 - CS4953xx Firmware User's Manual The intended audience for the CS4953xx Data Sheet is the system PCB designer, mcu programmer, and the quality control engineer. 2. Overview The CS4953xx DSP Family, together with Cirrus Logic's comprehensive library of audio processing algorithms, enables the development of next-generation audio solutions. Cirrus Logic also provides a broad array of digital interface products, audio converters, and ARM(R) Processors to meet your audio system-level design requirements. There are two devices in the CS4953xx DSP family. The CS495303 and CS495313 are differentiated by internal memory size and DSP Firmware. The CS495303 is available in a 128-pin QFP package and the CS495313 is available in either a 128-pin or 144-pin QFP package. The audio processing features of the CS495313 are a superset of audio features available in the CS495303. Please refer to Table 2 on page 6 for the speed and firmware features of each device. PR EL IM * * * * * * 2.1 Migrating from the CS495xx(2) to the CS4953xx The CS4953xx was designed to provide an easy upgrade path from the CS495xx(2). Although 144-pin versions of the two devices are virtually identical with respect to external system connection, there are some small differences the hardware designer should be aware of: The PLL supply voltage on the CS4953xx is 3.3V vs. 1.8V on the CS495xx(2). The PLL filter topology is simpler when using the CS4953xx rather than the CS495xx(2). The CS4953xx adds support for 6-channel DSD input. The CS4953xx adds support for TDM mode on both audio input and output ports. The CS4953xx does not support external SRAM operation. The CS4953xx external SDRAM bus speed is fixed at 150 MHz vs. the 120 MHz max bus speed for the CS495xx(2). Some firmware modules also support a 75 MHz CS4953xx SDRAM bus speed. Please refer to AN288 for details. * The CS4953xx CLKOUT pin can output XTALI or XTALI/2. The CS495xx(2) can only output XTALI. 2.2 Licensing Licenses are required for all of the 3rd party audio decoding/processing algorithms listed below, including the application notes. Please contact your local Cirrus Sales representative for more information. 4 (R)Copyright 2008 Cirrus Logic, Inc. IN AR Y The scope of the CS4953xx Datasheet is primarily the hardware specifications of the CS4953xx family of devices. This includes hardware functionality, characteristic data, pinout, and packaging information. DS705PP2 CS4953xx Data Sheet 32-bit Audio Decoder DSP Family 3. Code Overlays The suite of software available for the CS4953xx family consists of an operating system (OS) and a library of overlays. The overlays have been divided into three main groups called Decoders, Mid-processors, and Postprocessors. All software components are defined below: 1. OS/Kernel - Encompasses all non-audio processing tasks, including loading data from external memory, processing host messages, calling audio-processing subroutines, error concealment, etc. 2. Decoders - Any Module that initially writes data into the audio I/O buffers, e.g. AC-3(R), DTS, PCM, etc. All the decoding/processing algorithms listed below require delivery of PCM or IEC61937-packed, compressed data via I2S- or LJ-formatted digital audio to the CS4953xx. 3. Mid-processors - Any module that processes audio I/O buffer PCM data in-place before the Postprocessors. Generally speaking, these modules alter the number of valid channels in the audio I/O buffer through processes like Virtualization (n 2 channels) or Matrix Decoding (2 n channels). Examples are Dolby ProLogic IIx and DTS Neo:6. 4. Post-processors - Any module that processes audio I/O buffer PCM data in-place after the Mid-Processors. Examples are Bass Management, Audio Manager, Tone Control, EQ, Delay, Customer-specific Effects, Dolby Headphone/Virtual Speaker, etc. The overlay structure reduces the time required to reconfigure the DSP when a processing change is requested. Each overlay can be reloaded independently without disturbing the other overlays. For example, when a new decoder is selected, the OS, mid-, and post-processors do not need to be reloaded -- only the new decoder (the same is true for the other overlays). Table 2 below lists the firmware available based on device selection. Please refer AN288 CS4953xx Firmware User's Manual for the latest listing of application codes and Cirrus FrameworkTM modules available. PR EL IM DS705PP2 (R)Copyright 2008 Cirrus Logic, Inc.

CS4953xx Data Sheet 32-bit Audio Decoder DSP Family CS4953xx Data Sheet 32-bit Audio Decoder DSP Family 4. Hardware Functional Description 4.1 DSP Core The CS4953xx is a dual-core DSP with separate X and Y data and P code memory spaces. Each core is a high-performance, 32-bit, user-programmable, fixed-point DSP that is capable of performing two memory access control (MAC) operations per clock cycle. Each core has eight 72-bit accumulators, four X- and four Ydata registers, and 12 index registers. Both DSP cores are coupled to a flexible DMA engine. The DMA engine can move data between peripherals such as the digital audio input (DAI) and digital audio output (DAO), external memory, or any DSP core memory, all without the intervention of the DSP. The DMA engine offloads data move instructions from the DSP core, leaving more MIPS available for signal processing instructions. CS4953xx functionality is controlled by application codes that are stored in on-board ROM or downloaded to the CS4953xx from a host mcu or external FLASH/EEPROM. Users can choose to use standard audio decoder and post-processor modules which are available from Cirrus Logic. 4.1.1 DSP Memory Each DSP core has its own on-chip data and program RAM and ROM and does not require external memory for any of today's popular audio algorithms including Dolby Digital Surround EX, AAC Multichannel, DTS-ES 96/24, and THX Ultra2. The memory maps for the DSPs are as follows. All memory sizes are composed of 32-bit words. Table 3.

Each resource has its own arbiter: X, Y, and P RAM/ROMs on DSP A; X, Y, and P RAM/ROMs on DSP B; external memory; and the peripheral bus. Modulo and linear addressing modes are supported, with flexible start address and increment controls. The service interval for each DMA channel as well as up to 6 interrupt events, is programmable.

IN AR Y DSP B 10k SRAM, 8k ROM 16k SRAM, 16k ROM 8k SRAM, 24k ROM The CS4953xx is suitable for Audio Decoder, Audio Post-processor, Audio Encoder, DVD Audio/Video Player, and Digital Broadcast Decoder applications. 7 CS4953xx Data Sheet 32-bit Audio Decoder DSP Family 4.2 On-chip DSP Peripherals 4.2.1 Digital Audio Input Port (DAI) The 12-channel (6 line) DAI port supports a wide variety of data input formats. The port is capable of accepting PCM, IEC61937, or DSD. Up to 32-bit word lengths are supported. Up to 6 channels of DSD are supported and internally converted to PCM before processing. The port has two independent slave-only clock domains. Each data input can be independently assigned to a clock domain. The sample rate of the input clock domains can be determined automatically by the DSP, which off-loads the task of monitoring the S/PDIF receiver from the host. A time-stamping feature allows the input data to be sample-rate converted via software. 4.2.2 Digital Audio Output Port (DAO) There are two DAO ports. Each port can output 8 channels of up to 32-bit PCM data. The port supports data rates from 32 kHz to 192 kHz. Each port can be configured as an independent clock domain in slave mode, or the ratio of the two clocks can be set to even multiples of each other in master mode. The two ports can also be ganged together into a single clock domain. Each port has one serial audio pin that can be configured as a 192 kHz S/PDIF transmitter (data with embedded clock on a single line). Note: Only one S/PDIF transmitter pin is available in the 128-pin package. 4.2.3 Serial Control Port 1 & 2 (I2C(R) or SPITM) There are two on-chip serial control ports that are capable of operating as master or slave in either I2C or SPI modes. SCP1 defaults to slave operation. It is dedicated for external host-control and supports an external clock up to 50 MHz in SPI mode. It is present in both the 144- and 128-pin packages. This high clock speed enables very fast code download, control or data delivery. SCP2 defaults to master mode and is dedicated for booting from external serial Flash memory or for audio sub-system control. SCP2 does not include the SCP2_BSY# pin in the 128-pin package. 4.2.4 Parallel Control Port PR EL IM 4.2.5 External Memory Interface 4.2.6 GPIO 4.2.7 PLL-based Clock Generator 8 The CS4953xx parallel port supports both Motorola(R) and Intel(R) interfaces. It can be used for both control and data delivery. The parallel port pins are multiplexed with serial control port 2 and are available in the 144-pin package. The external memory interface controller supports up to 128 Mbits of SDRAM, using a 16-bit data bus. The memory controller supports up to 1 MB of Flash memory in 8-bit data bus-width mode or 2 MB in 16-bit data bus-width mode. Many of the CS4953xx peripheral pins are multiplexed with GPIO. Each GPIO can be configured as an output, an input, or an input with interrupt. Each input-pin interrupt can be configured as rising edge, falling edge, active-low, or active-high. The low-jitter PLL generates integer or fractional multiples of a reference frequency which are used to clock the DSP core and peripherals. Through a second PLL divider chain, a dependent clock domain can be output on the DAO port for driving audio converters. The CS4953xx defaults to running from the external reference frequency and can be switched to use the PLL output after overlays have been loaded and configured, either through master boot from an external serial FLASH or through host control. A built-in crystal oscillator circuit with a buffered output is provided. The buffered output frequency ratio is selectable between 1:1 (default) or 2:1. (R)Copyright 2008 Cirrus Logic, Inc. IN AR Y DS705PP2 CS4953xx Data Sheet 32-bit Audio Decoder DSP Family 4.3 DSP I/O Description 4.3.1 Multiplexed Pins Many of the CS4953xx pins are multi-functional. For details on pin functionality please refer to the CS4953xx Hardware User's Manual. 4.3.2 Termination Requirements Open-drain pins on the CS4953xx must be pulled high for proper operation. Please refer to the CS4953xx Hardware User's Manual to identify which pins are open-drain and what value of pull-up resistor is required for proper operation. Mode select pins on the CS4953xx are used to select the boot mode upon the rising edge of reset. A detailed explanation of termination requirements for each communication mode select pin can be found in the CS4953xx Hardware User's Manual. 4.3.3 Pads The CS4953xx I/O operates from the 3.3 V supply and is 5V tolerant. 4.4 Application Code Security The external program code may be encrypted by the programmer to protect any intellectual property it may contain. A secret, customer-specific key is used to encrypt the program code that is to be stored external to the device. PR EL IM DS705PP2 (R)Copyright 2008 Cirrus Logic, Inc.
