PROBLEM TO BE SOLVED: To provide a signal transfer device capable of retaining a context of a read request and a write request even in a memory access by Posted-Write method via a data path having no mechanism for performing control to retain the context of the read request and the write request.SOLUTION: A signal transfer device 102 includes: an interface 205 that has a posted-write-method write data protocol for transferring data to a memory control device 103 for controlling an access to a common memory 101; and standby means 206 that, when there is a write request of writing in the common memory 101 via the interface 205, acquires a write address from the write request, and stands by read of the address until a transfer amount of write data exceeds a total amount of a buffer on a signal transfer path to the common memory 101.SELECTED DRAWING: Figure 1 |
