Abstract:
A communication processing device includes a communication data processing circuit that (i) issues an access request for a buffer specified by a descriptor, among a plurality of buffers in a first memory, and (ii) outputs a predetermined switching permission signal at a time when a data access for one of the plurality of buffers is completed. The communication processing device also includes a second memory and a transmission destination switching circuit. The second memory includes a plurality of alternative buffers corresponding to the plurality of buffers. The transmission destination switching circuit switches a transmission destination of the access request from one of the plurality of buffers in the first memory to one of the plurality of alternative buffers in the second memory, based on the switching permission signal.
