专利汇可以提供Cpu core专利检索,专利查询,专利分析的服务。并且PURPOSE: To improve the operation efficiency of a peripheral circuit by constituting a CPU core of an internal resource, a control circuit and a terminal group and connecting the internal resource so that all data are transmitting through an internal bus.
CONSTITUTION: The CPU core is constituted of the internal resource 10 including plural registers connected to one internal bus 11, a control circuit 20 for decoding an instruction and outputting various control signals to control the whole CPU core and the terminal group 30 for transmitting/receiving signals to/from the external. The resource 10 is connected so as to transmit/receive data through the internal bus 11. A bus control circuit 27 for inputting/outputting data between buses is included in the circuit 20 and connected so that its I/O is executed through the bus 11, a data bus DB and a peripheral data bus PDB. Consequently, the operation efficiency of the peripheral circuit can be improved, chip size can be contracted and peripheral circuit design matching with a market request can be attained.
