Document Type and Number:
Japanese Patent JP3316851
Kind Code:
B2
Abstract:
A VLSIC page printer controller includes an instruction processor which responds to a host computer and a printer video processor for accessing data from memory under the control of the instruction processor and serializing data for transfer to a printer through a video port. An I/O interface interconnects the printer controller with an I/O bus to which is connected a host computer, memory devices, and other peripheral devices. An internal memory interface connects the printer controller to memory, and the printer video processor is provided with direct memory access (DMA). Data and instruction caches and an instruction ROM are provided on-chip. A RISC instruction processing unit includes as an integral part thereof the special function circuits of orthogonal rotator, bit/byte mirror, and pixel modification.
