Abstract
PURPOSE: To realize a high-speed operation with an external circuit without increasing the number of external connecting terminals by providing a control means or the like to a high-speed arithmetic circuit attached externally to the 1-chip CPU to supply the arithmetic instruction or the like via the main bus.
CONSTITUTION: The CPU101 formed into a chip is provided along with the main bus 103 which transfers the data between the CPU and the external unit plus the high-speed arithmetic circuit 106 attached externally and connected selectively to the bus 103. In addition, the following means are provided: the control means which supplies the arithmetic instruction and the operand to the circuit 106 via the bus 103 and the control means which delivers the arithmetic result data obtained through the circuit 106 to the outside of the circuit 106 via the bus 103. For instance, as shown in the diagram the C-ROM102 into which the microprogram is stored, high-speed floating instruction execution circuit FPHW106, address converting mechanism and others are connected to the bus 103 via the gates G1WG8. In such constitution, an information processor is obtained.
