Pursuing its dream of seeing versions of its PowerPC RISC powering everything from washing machines through toys to supercomputers, IBM Corp’s Microelectronics unit in Hopewell Junction, New York has previewed its first microcontroller variant ahead of autumn launch. The PowerPC Embedded Controller 403GA is aimed at office peripherals and consumer video devices such as digital video cameras, personal communicators and networking. It has four-channel direct memory access, DRAM and input-output controllers, two-way set associative instruction and data caches, serial port, multi-level interrupt controller and multiple timer facilities. It will go into the television set-top boxes to be used in the Bell Atlantic Corp and Groupe Videotron Ltee trials.
