Description
The TMC2250A is a flexible high-performance nine-multiplier array VLSI circuit which can execute a cascadeable 9-tap FIR filter, a cascadeable 4 x 2 or 3 x 3-pixel image convolution, or a 3 x 3 color space conversion. All configurations offer throughput at up to the maximum guaranteed 50 MHz clock rate with 12-bit data and 10-bit coefficients. All inputs and outputs are registered on the rising edges of the clock.

FEATUREs
• Four user-selectable filtering and transformation functions:
    – Triple dot product (3 x 3) matrix multiply
    – Cascadeable 9-tap systolic FIR filter
    – Cascadeable 3 x 3-pixel image convolver
    – Cascadeable 4 x 2-pixel image convolver
• 50 MHz (20ns) pipelined throughput
• 12-bit input and output data, 10-bit coefficients
• 6-bit cascade input and output ports in all filter modes
• Onboard coefficient storage, with three-cycle updating of all nine coefficients

APPLICATIONs
• Image filtering and manipulation
• Video effects generation
• Video standards conversion and encoding/decoding
• Three-dimensional image manipulation
• Medical image processing
• Edge detection for object recognition
• FIR filtering for communications systems
