MICROCOMPUTER Russian patent published in 1995 - IPC

FIELD: microprocessor computer engineering. SUBSTANCE: device has central processing unit, input/output device, static memory unit. Address-information, address and control inputs and outputs of common bus are connected to central processor, input/output device and static memory unit. Interface unit of input/output device contains flip-flop and multiplexer which connect output of input/output device to its input. This results in possibility to test it by software. In addition memory control unit of static memory unit contains four XOR gates, two NAND gates, OR gate, flip-flop. They provide possibility to use last memory bank. EFFECT: increased functional capabilities. 13 dwg
