Abstract
The present invention relates to a time management system for a memory for processing a time-series data, such as animation image and a sound data. The time-series data is managed on a timewise basis so that it is possible to transfer the time-series data into a real memory without a swap-out/swap-in operation. The present invention includes a memory unit 5, a time measuring unit 3 including a time managing table 31 to manage a timing for acquisition/release of an area in the memory unit, and an area managing unit 4 including a user area time managing table 41 to manage the memory unit on a timewise basis in accordance with an area acquisition signal and an area release signal transferred from the time measuring unit. When the time measuring unit 3 detects a designated time, it requests an acquisition of the memory unit from the area managing unit 4, and when the time measuring unit 3 detects a time-out of the designated time, it sends a release of the memory unit request to the area managing unit 4.
