All eight multiplier inputs are accessible to the user and may be updated every clock cycle with integer or fractional two's complement data. A pipelined architecture, fully registered input and output ports, and asynchronous three-state output enable control simplify the design of complex systems. The data or coefficient inputs to the multipliers may be held over multiple clock cycles, providing storage for mixing and filtering coefficients. The 25-bit internal accumulator path allows two bits of cumulative word growth and may be internally rounded to 16 bits. Output data are updated every clock cycle, or may be held under user control. All data inputs, outputs, and controls are TTL compatible and (except for the three-state output enable) are registered on the rising edge of CLK. The TMC2246A is uniquely suited to performing pixel interpolation in image manipulation and filtering applications. As a companion to the Fairchild Semiconductor TMC2301 and TMC2302 Image Manipulation Sequencers, the TMC2246A can execute a bilinear interpolation of an image (4-pixel kernels) at real-time video rates. Larger kernels or other, more complex, functions can be realized with no loss in performance by utilizing multiple devices. With unrestricted access to all data and coefficient input ports, the TMC2246A offers considerable flexibility in applications performing digital filtering, adaptive FIR filters, mixers, and other similar systems requiring high-speed processing. Fabricated in a submicron CMOS process, the TMC2246A operates at a guaranteed clock rate of 60 MHz over the full temperature and supply voltage ranges. It is pin- and function-compatible with CADEKA's TMC2246, while providing higher speed operation and lower power dissipation. It is available in a 120 pin Plastic Pin Grid Array (PPGA), 120 pin Ceramic Pin Grid Array (CPGA), 120 lead MQFP to PPGA (MPGA), and a 120 lead Metric Quad FlatPack (MQFP).

The inputs are user-configurable, allowing latching of either the 10- or 11-bit input data. The data format is user-selectable between integer or fractional two's complement arithmetic. Total latency from input registers to output data port is 5 clocks. The output data path is 16 bits wide, providing the lower 16 bits of the accumulator when in integer format or the upper 16 bits of the 25-bit accumulator path when fractional two's complement notation is selected. One-time rounding to 16 bits is performed automatically when accumulating fractional data, but is disabled when operating in integer format to maintain the integrity of the least-significant bits. 2 REV. 1.0.3 9/11/00 TMC2246A PRODUCT SPECIFICATION Pin Assignments 120 Pin Plastic Pin Grid Array, H5 Package, 120 Pin Ceramic Pin Grid Array, G1 Package, and 120 Pin Metric Quad FlatPack to 120 Pin Plastic Pin Array, H6 Package 1 A B C D E F G H J K L M N Top View Cavity Up KEY 2 3 4 5 6 7 8 9 10 11 12 13 Pin A1 A2 A3 A4 A5 A6 A7 A8 A9 A10 A11 A12 A13 B1 B2 B3 B4 B5 B6 B7 B8 B9 B10 B11 B12 B13 C1 C2 C3 C4 Name ENSEL ENB2 ENB3 D47 D45 D42 D41 C410 C48 C46 C43 C40 C32 ACC FSEL ENB4 D49 D46 D43 D40 C49 C47 C44 C42 C30 C35 S15 OEN CLK ENB1 Pin C5 C6 C7 C8 C9 C10 C11 C12 C13 D1 D2 D3 D11 D12 D13 E1 E2 E3 E11 E12 E13 F1 F2 F3 F11 F12 F13 G1 G2 G3 Name D48 D44 GND VDD C45 C41 C31 C33 C36 S13 S14 OCEN C34 C37 C39 S11 S12 GND C38 C310 D30 S9 S10 VDD D31 D32 D33 S7 S8 GND Pin G11 G12 G13 H1 H2 H3 H11 H12 H13 J1 J2 J3 J11 J12 J13 K1 K2 K3 K11 K12 K13 L1 L2 L3 L4 L5 L6 L7 L8 L9 Name D35 D36 D34 S6 S5 VDD GND D38 D37 S4 S3 GND D27 D29 D39 S2 S1 D18 D23 D26 D28 S0 D17 D15 D12 C19 GND VDD C20 C24 Pin L10 L11 L12 L13 M1 M2 M3 M4 M5 M6 M7 M8 M9 M10 M11 M12 M13 N1 N2 N3 N4 N5 N6 N7 N8 N9 N10 N11 N12 N13 Name C28 D20 D24 D25 D19 D14 D11 C110 C17 C15 C13 C10 C22 C25 C29 D21 D22 D16 D13 D10 C18 C16 C14 C12 C11 C21 C23 C26 C27 C210 REV. 1.0.3 9/11/00 3 PRODUCT SPECIFICATION TMC2246A Pin Assignments 120 Lead Metric Quad Flat Pack (KE) Package 120 1 Pin 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 Name CLK FSEL ACC OCEN OEN S15 S14 GND S13 S12 S11 VDD S10 S9 S8 GND S7 S6 S5 VDD S4 S3 S2 GND Pin 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 Name S1 S0 D19 D18 D17 D16 D15 D14 D13 D12 D11 D10 C110 C19 C18 C17 C16 GND C15 C14 C13 VDD C12 C11 Pin 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 Name C10 C20 C21 C22 C23 C24 C25 C26 C27 C28 C29 C210 D20 D21 D22 D23 D24 D25 D26 D27 D28 D29 D39 GND Pin 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 Name D38 D37 D36 D35 D34 D33 D32 D31 D30 C310 C39 C38 C37 C36 C35 C34 C33 C32 C31 C30 C40 C41 C42 C43 Pin 97 98 99 100 101 102 103 104 105 106 107 108 109 110 111 112 113 114 115 116 117 118 119 120 Name C44 C45 C46 C47 C48 VDD C49 C410 D40 GND D41 D42 D43 D44 D45 D46 D47 D48 D49 ENB3 ENB2 ENB1 ENB4 ENSEL 4 REV. 1.0.3 9/11/00 TMC2246A PRODUCT SPECIFICATION Pin Descriptions Pin Number Pin Name Power VDD GND Clock CLK C3 1 System Clock.

Coefficients input during the current clock are assumed to be in fractional two's complement format. Rounding to 16 bits is performed as determined by the accumulator control, ACC, and the upper 16 bits of the accumulator are output when the registered Format Select input (FSEL) is LOW. When FSEL is HIGH, two's complement integer format is assumed, and the lower 16 bits of the accumulator are presented at the output. No rounding is performed when operating in integer mode. See the Functional Block Diagram and the Applications Discussion. Enable Select. The registered Enable Select determines whether the data or the coefficient input registers may be held on the next rising edge of clock, in conjunction with the individual input enables ENB1-ENB4. See Table 1. Input Enables. When ENBi (i=1, 2, 3, or 4) is LOW, registers Ci and Di are both strobed by the next rising edge of CLK. When ENBi is HIGH and ENSEL is LOW, Di is strobed, but Ci is held. When ENBi and ENSEL are both HIGH, Di is held and Ci is strobed. See Table 1. Thus, either or both input registers to each multiplier are updated on each clock cycle. Accumulate. When the registered ACCumulator control is LOW, no internal accumulation will be performed on the data input during the current clock, effectively clearing the prior accumulated sum. If operating in fractional two's complement format (FSEL = LOW), one-half LSB rounding to 16 bits is performed on the result. This allows the user to perform summations without propagating roundoff errors. When ACC is HIGH, the internal accumulator adds the emerging products to the sum of previous products, without performing additional rounding. OCEN D3 4 Output Register Enable. The output of the accumulator is latched into the output register on the next clock when the Output Register Clock Enable is LOW. When OCEN is HIGH the contents of the output register remain unchanged; however, accumulation will continue internally if ACC remains HIGH. Output Enable. Data currently in the output registers is available at the output bus S15-0 when the asynchronous Output Enable is LOW. When OEN is HIGH, the outputs are in the high-impedance state. Not Connected.

Application Notes Typical Operation The versatile input clock enables and unrestricted data and coefficient inputs provided on the TMC2246A allow considerable flexibility in numerous image and signal processing architectures. Table 2 shows a typical sequence of operations which clarifies the inherent latencies of the device and illustrates fixed coefficient storage, product accumulation, and device reconfiguration prior to beginning a new accumulation. This assumes that the device is set to fractional two's complement mode (FSEL = LOW) with OCEN = LOW, OEN = LOW, and the input registers configured to hold coefficients only (ENSEL = LOW). X= "don't care." Using the TMC2246A for Pixel Interpolation As a companion product to the TMC2301 Image Resampling Sequencer, the TMC2246A offers an excellent tool for performing high-speed pixel interpolation and image filtering. Any pixel resampling operation with multiple-pixel kernels must utilize some parallel-processing technique, such as memory banding, to maintain high-speed image throughput rates. Memory banding utilizes adders to generate parallel offset addresses, allowing the user to access multiple pixel locations simultaneously. Using such techniques, one TMC2246A can perform bilinear interpolation (four-pixel kernel) with no loss in system performance. Larger kernels can be realized in similar systems with additional TMC2246As. Figure 5 illustrates a basic pixel interpolation application. 10 REV. 1.0.3 9/11/00 TMC2246A PRODUCT SPECIFICATION Table 2.

Longer filters, with more taps, are realized by including an external adder (such as the common 74381 type) to cascade multiple TMC2246As.
