Computer system having dual bus architecture with audio/video/CD drive controller/coprocessor having integral bus arbitrator

摘要: A computer system for high-performance video and audio manipulations comprising a locked memory cartridge an audio/video/compact disk (CD) drive controller/coprocessor. The has central processing unit (CPU) with at least one bus associated therewith, the having line. comprises readable memory, control circuit, lock connector all in circuit communication each other. allows to be pluggably connected CPU. scrambles some of lines, thereby scrambling data on reset, unscrambles lines responsive inputs from circuit. monitors bus, waiting proper combination values asserted onto which time causes unscramble lines. audio/video/CD controller/coprocessor CPU interface, cache, controller, arbitrator, DRAM refresher, CD digital signal processor (DSP) sound coprocessor, “blitter” graphics coprocessor integrated package.
