VIDEO CONTROLLER Russian patent published in 1994 - IPC

FIELD: computer engineering. SUBSTANCE: register unit 8, multiplexer 14, memory 6, where state and control data are stored, memory unit 7 and interrupt controller 9 are introduced to accomplish the goal of invention. This results in decreased address space for access to registers and peripheral devices. This also results in possibility of data exchange with direct access to computer memory. EFFECT: increased field of application, simplified design of state registers, control registers and control logic dealt with each bit in registers of peripheral devices. 17 dwg
