一种缓存访问方法、装置、设备及存储介质
By using arbitration logic to determine the update field of the target data and directly update it when accessing the QPC cache through the RDMA network card, the problem of low efficiency in reading target information from the QPC cache is solved, and efficient cache access and data consistency are achieved.

AI Technical Summary
Technical Problem
When reading target information from the context cache (QPC cache) in the RDMA network card access queue, two request operations are required, resulting in low cache access efficiency.
Method used
By receiving read requests and update signals from the RDMA network card, the arbitration logic of the QPC cache is used to determine the update field of the target data, and the update is performed directly when the QPC cache is hit, avoiding additional write request operations.
Benefits of technology
It improves the efficiency of cache access, reduces latency, avoids data conflicts, and maintains the consistency of QPC cache.

Abstract
本公开提供一种缓存访问方法、装置、设备及存储介质，该方法应用于QPC cache，包括：接收由RDMA网卡发送的读请求和第一更新信号；第一更新信号用于指示QPC cache对目标数据进行的更新操作的操作类型；目标数据为读请求所请求的数据；在命中QPC cache的情况下，响应于读请求向RDMA网卡发送目标数据，并基于预设的仲裁逻辑确定目标数据中进行更新的目标字段；根据操作类型和目标字段，对目标数据进行更新。通过本公开，可以提高缓存访问的工作效率。
