Semiconductor integrated circuit device
专利汇可以提供Semiconductor integrated circuit device专利检索，专利查询，专利分析的服务。并且PURPOSE: To simplify the information processing system by forming a microprocessor and a CRT control circuit into a one-chip semiconductor integrated circuit to use its address terminal in common.
CONSTITUTION: A semiconductor integrated circuit LSI is provided with a microprocessor CPU, a CRT control circuit CRTC and a multiplexer MPX. An address signal AD1 from the CPU and an address signal AD2 from the circuit CRTC are fed to the MPX2, the signals are switched in terms of time division by using a system clock from a pulse generating circuit PG and the address signal formed in common is fed to a refresh memory RM through an address bus AD. Further, an arithmetic logical unit ALU and the memory RM of the CPU are connected by a data bus DA. Then an idle period for the CPU is provided within one period of the clock from the CPU and an address signal of the RM formed by the circuit CRTC is outputted to the address bus AD.
