Targeted for use in high-performance personal digital assistants (PDAs) and interactive communications products, the TMPR3922U 166-MHz, 2.5V/3.3V five-stage pipelined processors are based on firm's TX39 RISC processor core and the R3000A architecture from MIPS Technologies Inc. On-chip features include an integrated translation lookaside buffer that supports Windows CE operating systems and improve entry-swapping performance. A high-speed multiplier and accumulator executes 32-bit x 32-bit multiplier operations with a 64-bit accumulation in a single clock cycle to support software modems (V.34, 28.8 kbps) and a variety of memory controllers.
