Performance
RISC stands for Reduced Instruction Set Computer. The smaller, fixed-length instruction set of a RISC processor
allows fast program execution. Compared to the conventional CISC (Complex Instruction Set Computer), the RISC
processor's simplified circuit structure offers attractive features such as increased execution speed and reduced power
consumption.
Toshiba has adopted the RISC processor technology developed by MIPS Technologies, Inc. In addition to the 32-bit
processor TX39 Family for embedded use, Toshiba has also developed the TX19 Family of processors, featuring an
additional 16-bit instruction set, and the 64-bit TX49 and TX99 Family of processors for embedded use. The TX19,
TX39, TX49 and TX99 families serve as CPU cores, which, together with megacells for peripherals, offer solutions for
the implementation of ASICs.
