PURPOSE: A transmitting system, an apparatus, and a method are provided to implement an error relief with a simple control by reducing a circuit amount. CONSTITUTION: A computer system(1) comprises an IOP(10) and an arithmetic and logic unit(20). The processing unit and the arithmetic and logic unit are connected to a serial transmission passage. The IOP is connected to the computer system external, which is the input/output device. The IOP comprises a request handling unit(11), a request receiver(12), a response receiving part(13), a timer(14) and an inside and input-output device controller(15). The arithmetic and logic unit processes a request received from IOP. The arithmetic and logic unit is connected to a first memory(31) and a second memory(32). The operation processing unit comprises a response processor(21), a request receive part(22), and a reply transmission part(23), and a memory access controller(24). |
