Abstract

The embodiment of the invention discloses an asynchronous RAM (Random Access Memory) read-write method and device, terminal equipment and a readable storage medium. Therefore, the asynchronous RAM can ensure that the read operation of the asynchronous RAM is paused (namely, the position of a read pointer Rdr is kept unchanged) under different read-write frequencies under the conditions that the write address at the current moment minus the read address at the current moment is less than a first threshold value and equal to or greater than 0, and the full-write mark of the asynchronous RAM indicates that the asynchronous RAM is not full, the write operation of the asynchronous RAM is kept normal (namely, the write pointer Wdr moves normally). According to the method and the device, the data is ensured to be normally written into the address with empty data, and the distance between the write pointer Wdr and the read pointer Rdr is increased to avoid read-write conflicts, so that the asynchronous RAM can stably read and write the data, and the stability of the storage process is ensured.

Description

technical field

[0001] The invention relates to the field of memory, in particular to an asynchronous RAM reading and writing method, device, terminal equipment and readable storage medium. Background technique

[0002] According to different sampling clocks, random access memory (Random Access Memory, RAM) can be divided into synchronous RAM and asynchronous RAM. Synchronous RAM means that the same clock is used for reading and writing. For RAM, since the frequency of the write clock is different from that of the read clock, it may cause conflicts between reading and writing of RAM data, thereby affecting effective writing and reading of RAM data. Contents of the invention

[0003] In view of the above problems, the present application proposes an asynchronous RAM reading and writing method, device, terminal equipment and readable storage medium.

[0004] The present application proposes an asynchronous RAM reading and writing method, the method comprising:

[0005] Obt...
