Abstract
A FIFO device includes: a FIFO buffer that holds a transfer request transferred from a bus and including a write address, a data size, and write data, and outputs the transfer request to a bus; and a transfer request generation unit that receives, from the bus, a first transfer request and a second transfer request subsequent to the first transfer request, to determine whether the second transfer request can be combined with the first transfer request based on a write address and a data size of the first transfer request and a write address and a data size of the second transfer request, and when determining that the transfer requests can be combined together, holds a combined transfer request obtained by combining the first transfer request and the second transfer request together, to store the combined transfer request in the FIFO buffer.
