Embodiment Construction
[0036] Compared with the traditional buffer manager, the invention adds a buffer aging module, expands the information recorded by the buffer information recorder, and adds time information of buffer allocation and aging marks. Each record entry of the buffer information recorder is in one-to-one correspondence with a buffer. The buffer information recorder is used to record the relevant information of each buffer, including whether the buffer is idle or being used, the time when the buffer is allocated, and whether the buffer is aged. In order to prevent the buffer from being aged incorrectly, the buffer aging flag is set in the buffer recorder. For example, when the flag is 1, it means that the buffer has just been allocated, and when the flag is in the aging state A value of 0 indicates that the buffer has not been used for a long time. When the aging timing period of the timer set for regularly performing buffer aging detection arrives, the control logic entity scans the ...
