Abstract

PURPOSE:To transfer data at higher speed by providing information for transferring the data of one byte or the data of two bytes in a data request signal and a data response signal. CONSTITUTION:The data request signal of the two bytes SRVICE.IN2 105, DATA.IN2 107 and the response data response signal of the two bytes SRVICE.OUT2 106, DATA.OUT2 108 are added. In a transfer sequence. The signal 105/signal 107 indicates that a I/02 requests the data of the two bytes to a channel device 1 and all data on a two byte bus (BUS 0, BUS 1) is valid. The device 1 processes the data when the data which can respond is constituted of the two bytes and responds to the signal 106/signal 108. In such a way, the one byte or the two bytes of the request is discriminated immediately after a receiving, so that a response can be rapidly executed ad and a data.buffer, register or the like can be updated at an early time, thereby, the high speed data transfer can be attained.
