1. General Description
The W90100 Embedded Micro-controller is part of Winbond
s W90K Embedded processor family.
The W90100 is a high-performance, highly integrated 32-bit processor and it is designed to be easily interfaced
to a variety of laser printer mechanisms including: laser, ink-jet and thermal types.
The W90100 CPU core is based on the HP PA-RISC architecture and is upward code compatible
with the W90K. The PA-RISC architecture incorporates traditional RISC elements, such as instruction
pipelining, a register-to-register instruction set and a large, general-purpose register file. Separate on-chip
instruction and data caches allow the W90100 to fetch an instruction and access data in a single processor
cycle.
The W90100 includes several features that greatly increase performance, reduce system component
count and ease the overall system design task in a printer application. These features include a DRAM
controller, FLASH ROM controller, serial port with FIFO, IEEE 1284 parallel port, timer/counters,
Programmable I/O port, DMA controller, DPI interface, and enhanced debug support; all features that are
commonly required in general embedded applications. In addition, the W90100 supports generic printer video
and communications interface signals for easy interfacing with generic laser printer engine. To further increase
the overall performance of the W90100 printer system, both image enhancement, including edge
enhancement and gray scale enhancement; as well as frame memory compression are integrated into the
W90100 micro-controller.
