Data processing system
专利汇可以提供Data processing system专利检索，专利查询，专利分析的服务。并且PURPOSE: To execute the memory access at a high speed by using a serial port and a random port in the case of an instruction fetch and a data operation, respectively with respect to a memory access request from a processor.
CONSTITUTION: The system is constituted of a microprocessor 101, a read-only memory for holding a fundamental program, a dual port memory (DP-RAM) 103, a random port control circuit 104 for generating a control signal of a random port of the DP-RAM, a serial port control circuit 105 for generating a control signal serial port of the DP-RAM, a deciding circuit 106 for deciding by which of the random port and the serial port an access is executed, a peripheral processor 107 and a clock generator 108. In such a state, with respect to a memory access request from the processor 101, the serial port and the random port are used in the case of an instruction fetch and a data operation, respectively. In such a way, the memory access can be executed at a high speed.
