device features: the highly integrated dmn-8600 features the following: ? dual 150 mips risc architecture with integrated audio dsps, i-cache and memory, host functions 2d graphics engine with dvd sub- picture decode and 32-bit rgba flexible video and motion estimation processors high-performance memory controller with a 32-bit data bus for support of 8-64 mb of external sdr/ddr/sdram ieee1394 link layer (with 5c copy protection) mpeg-2 mp@ml codec dv-25 codec trueview pro tm temporal filtering for pre-encode noise filtering truescan pro tm de-interlacing for progressive display output real-time vbr encoding external generic host bus interface serial i/o interface controller for infrared port, general-purpose serial i/o, modem, etc. storage device interface controller for ide/atapi devices or non-atapi devices (low-cost optical loaders) with the highest level of integration, broadest feature set, best image quality, and configurable software development environment, the lsi logic dmn-8600 brings unprecedented features to dvd recorder applications. it also optimizes time-to-market and system cost performance for consumer electronics manufacturers. capabilities the dmn-8600 delivers four times the processing performance of previous generation video codecs. the dmn-8600 has been optimized for performance-critical functions at the bit- and pixel-operations level with firmware that has been optimized for performance and scalability. this balance delivers the flexibility needed to cut time-to-market and lower develop- ment cost. the dmn-8600 is capable of a high degree of concurrency. examples of this are simultaneous encoding and decoding in mpeg-2 mp@ml format, simultaneous decoding to mpeg-2 mp@ml and transcoding to dv-25, multi- angle view decoding, dv-25 to mpeg-2 with zero delay preview, cd-da to mp3 transcoding, as well as ieee1394 transport stream muxing and demux- ing. system design the dmn-8600?s high level of integration drastically reduces system component count, and consequently system cost. figure 2 shows a block diagram of an advanced dvd recorder based on dmn-8600. the dmn-8600 has an on-chip atapi controller that supports read- only dvd rom drives, rewriteable dvd drives (dvd-ram, dvd-rw, or dvd+rw), or ide compatible hard disk drives. the dmn-8600 is able to record a single input from a tv tuner, a standard analog input, the ieee1394 link, or the atapi interface, in mpeg-1, mpeg-2 or dv-25 format. similarly, it is capable of decoding all standard dvd/vcd/svcd/mp3 for mats (including dvd-audio) and sending the result to the video and audio output. the built-in support for progressive video (54 mhz) enables 480p video output. a dv-25 camcorder may be hooked up to the ieee1394 port for transcoding to mpeg-2 format. lsi logic DIMENSION ? 8600 dvd recorder system processor rf tuner s/pdif controller audio dacs rom/flash iec958 audio out video out ieee1394 sdram vdenc 1394 phy ntsc/pal decoder audio adc audio in video in record drive vfd with front panel controller figure 2: dmn?-8600 dvd recorder system design based on dmn?-8600
internal architecture details the dmn-8600 can accomplish very compute-inten- sive signal processing tasks because it integrates multiple high-performance processing modules on a single chip. risc engine two 32-bit sparc processors perform all of the following functions: system processing, audio processing, and high-level flow control and and decision-making tasks for video processing, and 2d graphics processing. video dsp as a highly integrated processor engine, the dmn-8600 is designed to implement motion-compensated, block-dct-based video compression algorithms. to this end, the dmn-8600 includes a video dsp and motion estimation (me) coprocessor that off-loads compute-intensive tasks from the sparc processors. motion estimation coprocessor the programmable me coprocessor has a throughput of 29 billion arithmetic operations per second (bo ps). it takes the me commands from the sparc processor and generates results for each target. video dsp coprocessor the video dsp coprocessor performs vector memory- to-memory instructions. this improves code density and off-loads the sparc processors. its 64 kbyte data memory is double-buffered (two banks) to allow concurrent dma and dsp operations. some of the functions that the dsp coprocessor performs include: de-telecine, activity measures, motion compensation, adaptive temporal and de-interlace filtering, linear filtering/decimation, dct/idct (up to 12 bits), quantization/dequantization, and variable length encoding/decoding. the video dsp coprocessor operates at approximately 16 bops. audio processing the audio processing hardware is physically inte- grated into each sparc processor. the hardware consists of two parallel 64-bit mac units with 32-bit precision, and a dsp instruction set to support efficient encoding and decod- ing of a wide variety of audio algorithms, including mpeg-1 layer 2, dts, mp3, dolby digital tm , aac, mlp, and wma. in addition, audio special effects such as 3d audio, dolby prologic ? , echo, harmonizing, bass management, fir and iir filters are supported. each sparc processor can execute two instructions in parallel, a mac operation (dsp instruction) and a regular sparc processor instruction. programmability the dmn-8600 is compatible with lsi logic?s proprietary c-ware sw develoment environment. c-ware is an object oriented software architecture that abstracts the underlying hardware. this promotes portability and application re-usability within and across lsi logic?s product families. figure 4 shows the basic c-ware architec- ture and how it supports cross-product compatibility. audio / video if motion estimation 29 bops generic host 1394 link if sdram controller tmem wmem dmem (16 kb) i cache (16 kb) i cache (16 kb) rmem video dsp 16 bops amem risc cpu & audio dsp risc cpu & audio dsp 150 mips 150 mips storage if sio 32-bit bus sdr/ddr sdram 8 mb - 64 mb 16/32-bit generic host dvd - rx ieee1394 phy yuv video inputs yuv video output 8-channel audio_out 4-channel audio_in dual uarts ir rx/tx spi idc figure 3: dmn?-8600 architecture
