INMOS TO FOLLOW UP CLUT COUP WITH A110 DIGITAL SIGNAL PROCESSOR

Having scored a singular coup in the graphics market by winning IBM’s support for its CLUT Colour Look-Up Table chip in the Personal System/2, for its next trick, Inmos International Ltd reportedly plans to address another aspect of the graphics market next year. On the stocks at the Thorn EMI Plc subsidiary is a cascadeable digital signal processor, the A110, which the company claims will wipe the floor with other signal processing chips in some video applications – another reason for the interest in the company shown by Next Inc and Atari Corp? Inmos says that the 1.2 micron CMOS part will integrate a 21-stage multiply/accumulate array that will be able to execute 480 8-bit multiplications when the A110 is clocked at 20MHz – about 100 times faster than the Texas Instruments TMS32020. It will be able to execute two dimensional as well as one-dimensional convolutions and will include an on-chip back-end processor to process filtered data without additional components. Samples are set for the spring, production autumn.
