ARITHMETIC PROCESSING DEVICE, ITS ARITHMETIC PROCESSING METHOD, AND STORAGE MEDIUM STORING ARITHMETIC PROCESSING PROGRAM

摘要

An arithmetic processing device includes a first storage for storing processing contents in a state where the processing contents are associated with addresses, a second storage for storing each of the addresses of the processing contents stored in the first storage, a holding portion, a reading portion-for successively reading the addresses stored in the second storage and outputting the read addresses to the holding portion, and an execution portion for reading the processing content corresponding to the address output from the holding portion from the first storage and executing the read processing content. When the holding portion holds no address, the holding portion temporarily holds the address read by the reading portion and outputs the held address, whereas when the holding portion holds the address, the holding portion waits for completion of the execution of the processing content by the execution portion and outputs the held address after the completion of the execution.
