Abstract:
1. A memory block reclaiming judging apparatus comprising a peripheral information accessing unit, a data packet information recording unit, a data calculating unit, and a comparing and judging unit, wherein, the peripheral information accessing unit is configured to buffer and read required scheduling times for a data packet and single-time scheduled information, and transmit the required scheduling times for the data packet and the single-time scheduled information to the data calculating unit; the data packet information recording unit is configured to store remaining scheduling times of the data packet and a flag for indicating acquirement of information of the required scheduling times; the data calculating unit is configured to calculate remaining scheduling times of the data packet based on the required scheduling times for the data packet and the single-time scheduled information, and write the remaining scheduling times of the data packet into the data packet information recording unit, and meanwhile set the flag for indicating acquirement of information of the required scheduling times as valid; and the comparing and judging unit is configured to generate a memory block reclaiming instruction when it is judged that the remaining scheduling times of the data packet is 0 and the flag for indicating acquirement of information of the required scheduling times is valid, reset the remaining scheduling times of the data packet in the data packet information recording unit to an initial value, and set the flag for indicating acquirement of information of the required scheduling times as invalid.
