摘要： A command processing apparatus and method are provided for optimally processing commands issued asynchronously from a plurality of masters to a storage apparatus including a plurality of banks, where each master issues commands for a bank 0 and a bank 1 alternately. The command processing apparatus includes buffer units that obtain commands issued from the plurality of masters, an arbitration unit that arbitrates the obtained commands, and an issuance unit that issues commands to the storage apparatus according to the arbitration. The arbitration unit reads the commands of the plurality of masters obtained in the buffer units, and selects one command as a result of arbitration. The arbitration unit waits until a next command of a master relating to the selected command becomes readable, and reads the next command. The issuance unit consecutively issues the selected command and the read command to the storage apparatus.

摘要： The information processing device in the present invention includes a memory 1 which is a DRAM featuring a burst mode, and burst-transfers data at successive column addresses, masters (13), (14), and (15) which issue access requests, and a command processing unit (11) which converts an access address that is included in the access request issued from each master. One or more of the masters access an M×N rectangular area where M and N are integers, and the command processing unit (11) converts access addresses so that a column address of data at the (K+m)th column, where K and m are integers and m≦M, of an Lth line, and a column address of data at a Kth column of an (L+n)th line, where L and n are integers and n≦N, become successive.
