Abstract
PURPOSE: To realize a compact-design and high operation speed CPU by performing the LSI formation for the CPU and the advanced taking of the order.
CONSTITUTION: The information read out from main memory device 100 is registered into instruction register 202, and the OP part of register 202 is decoded by decoder 203 to decide which address of ROM205 the sequence starts from. This decoded address is registered in ROM address register 204. Based on the address signals sent from register 204, the data is read out from ROM205 to be then registered into microinstruction register 209. The data, if its bit length is larger than the common bus, is divided to be registered into the register. The common bus features 16 bits to perform the transfer between the CPU and the I/O, and the data length longer than the common bus will do.
