Title: INFORMATION PROCESSING SYSTEM, SEMICONDUCTOR INTEGRATED CIRCUIT, AND INFORMATION PROCESSING METHOD
Abstract:
The present invention increases the processing speed of an information processing system. A semiconductor integrated circuit (11) specifies, on the basis of memory map information (11m) that is defined by the address of the memories (14, 15) respectively used by semiconductor integrated circuits (11, 12), an address (a1) of a memory (15) connected to the semiconductor integrated circuit (12) that is the destination for data transmission, converts the address (a1) to the address (a3) of the memory (15) that is defined in memory map information (12m) referenced by the destination for data transmission, and uses a PCIe interface (11d) to output the address (a3) and the transmission data, a switch (13) uses PCIe interfaces (13a, 13b) to transfer the address (a3) and the transmission data to the destination for data transmission, and the destination for data transmission uses a PCIe interface (12d) to receive the address (a3) and the transmission data and writes the transmission data into a reception buffer region in the memory (15) corresponding to the address (a3).
