    • 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.
    • 提供了一种命令处理装置和方法,用于最佳地处理从多个主机异步发出的包括多个存储体的存储装置的命令,其中每个主机交替地为存储体0和存储体1发出命令。 命令处理装置包括获取从多个主机发出的命令的缓冲器单元,仲裁所获得的命令的仲裁单元和根据仲裁向存储装置发出命令的发布单元。 仲裁单元读取在缓冲器单元中获得的多个主器件的命令,并且作为仲裁结果选择一个命令。 仲裁单元等待直到与所选择的命令相关的主机的下一个命令变得可读,并读取下一个命令。 发行单元将选择的命令和读取命令连续地发送到存储装置。

    • 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.
    • 本发明的信息处理装置包括:存储器1,其是具有突发模式的DRAM,并且在连续的列地址突发传送数据,发出访问请求的主机(13),(14)和(15),以及 命令处理单元(11),其转换从每个主机发出的访问请求中包括的访问地址。 一个或多个主机访问M×N矩形区域,其中M和N是整数,并且命令处理单元(11)转换访问地址,使得在(K + m)列的数据的列地址,其中K m是第L行的m和nlE; M,第(L + n)行的第K列的数据的列地址,其中L和n是整数,并且n≦̸ N成为连续的。
