Abstract:
A serial interface circuit for performing transmission and reception of an asynchronous packet between its own node and another node connected to its own node via a serial interface bus, comprising:a storage means for storing data; a transmission packet generation circuit for generating a request packet containing a size of data to be transferred when transferring the data of the other node to its own node, a comparison means for comparing the size of data requested by the request packet and remaining amount of the storage means, and a data processing circuit which, when the result of the comparison of the comparison means is that the remaining amount of the storage means is larger than the requested size of data, transmits the request packet to the serial interface bus and which, when receiving a response packet with respect to the request packet from the other node, stores at least the data portion of the response packet in the storage means.
