An apparatus, method, device and medium for memory management

By setting up memory management modules on both the master and slave sides of the SDIO bus, the remaining memory capacity can be obtained and updated, thus solving the buffer blockage problem of the SDIO-wifi module when the network is not smooth. This ensures the reliability and determinism of data transmission and avoids adverse effects on the business layer.

AI Technical Summary

Technical Problem

When the network is unstable, the SDIO-wifi module cannot send data packets in time, which leads to the buffer being full and the failure of data transmission tasks in the business layer. This situation occurs frequently, especially in low-memory embedded devices, and affects the normal business communication of the business layer.

Method used

Recording and transceiver modules are set up on the master and slave sides of the SDIO bus, respectively. By acquiring and recording the remaining memory capacity of the slave side during the initialization phase, the data packet is sent only when the data size is not greater than the remaining memory capacity, and the remaining memory capacity is updated after each transmission. The master side can also start a query task to update the remaining memory capacity according to preset conditions.

Benefits of technology

Even in situations with poor network connectivity, host-side memory management ensures the determinism and reliability of data transmission, avoiding adverse effects of network issues on the business layer and reducing the probability of data transmission failure.

Abstract

Embodiments of the present application provide a memory management device, method, electronic equipment and computer readable storage medium, and relate to the field of embedded. Including the device applicable to the host end and the slave end of the SDIO bus, wherein the device of the host end includes a recording module and a transceiver module: the recording module is used for obtaining and recording the remaining memory capacity, the remaining memory capacity is the remaining capacity of the memory space in the slave end for caching the first data packet; the transceiver module is used for receiving the transmission instruction carrying the first data packet sent by the service layer of the host end, and is also used for sending the first data packet to the slave end if the data amount of the first data packet is not greater than the recorded remaining memory capacity, and the recording module is also used for updating the recorded remaining memory capacity. Therefore, even in the environment of not smooth network, the host end can still ensure the determinacy and reliability of the transmission data process through the device, thereby avoiding the adverse effects caused by the not smooth network on the service layer.
