INTER-END POINT COMMUNICATION CONTROL DEVICE AND METHOD IN IO ACCESS COMMUNICATION SYSTEM

PROBLEM TO BE SOLVED: To provide a communication control device and method by which an IC access can be autonomously performed at an end point side to another end point. SOLUTION: The inter-end point communication control device is configured to perform the communication control of an end point (EP) in a PCIe system, and provided with: a port (102) for communicating with a low order EP; a PCIe port (101) for communicating with high order communication equipment; a control part (105) for performing the synchronous processing of control information to associate EP as the object of IO access with each other between itself and a CPU; an RTI function part (103) for executing processing to transfer data received from the port (102) to a transfer EP by referring to the control information, and transmits the data through the PCIe port (101); and an RTO function part (104) for executing the data received from the PCIe port (101) to the transfer EP by referring to the control information, and transmitting the data through the port (102).
