TMC2250A中文资料仙童半导体数据手册PDF规格书

描述 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.

特性 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
