Compuation processing device, computation processing method thereof, and storage medium whereupon computation processing program is stored

A computation processing device comprises: a first storage means for associating and storing a plurality of pieces of processing content with addresses; a second storage means for storing each address of the plurality of pieces of processing content which is stored in the first storage means; a retaining means for temporarily retaining the addresses; a read-out means for sequentially reading out the addresses which are stored in the second storage means and having the retaining means output same; and an execution means for reading out from the first storage means and executing the processing content which corresponds to the address which is outputted from the retaining means. If no address is retained, the retaining means temporarily retains and outputs the address which is read out by the read-out means, and if the address is retained, the retaining means waits for the completion of the execution of the processing content by the execution means, and outputs the retained address. Overhead of switching between each process is thus alleviated, and it is possible to improve overall computational performance.
