16-MHz RISC microprocessor strips down for action. (Advanced Micro Devices' 29205)(EDN-Processor Update) (Product Announcement)

EDN, September, 1992 by Weiss, Ray

RISC [mu]Ps are making it big in the embedded-systems world, especially in printers, X-terminals, and communications gear. In these arenas the push is on for cheaper, minimal RISCs (reduced-instruction-set computers). AMD's newest member of the 29K family, the 29205, aims to please. A stripped-down 29200, the 29205 delivers four native MIPS sustained, on a 16-bit data bus.

The 29200 was designed specifically for printer-type applications. It interfaces to video RAM, produces printer-control signals, and provides a range of peripheral interfaces. The 29205 trims away the overhead for low-cost, down-in-the-dirt applications. The external memory bus is trimmed from 24-bit address and 32-bit data lines, to 22-bit address and 16-bit data lines. Video-RAM...
