Abstract

The invention relates to the technical field of mixed memory, and provides a heterogeneous mixed memory fast access optimization method and system. The method comprises the steps: optimizing the command processing overhead of the NVMe protocol; after optimizing the command processing overhead of NVMe protocol, Endpoint is applied to poll the command queue when the command is started; and the tracking bit content in the polling receiving buffer is applied to test arrival of the DRAM load and the change of the tracking bit indicates completion of the read command so as to solve the problem of speed mismatch between NVM memory access and DRAM memory access, fast access to the NVM memory on the heterogeneous mixed memory platform based on the NVM extended system memory, improve the overall memory access performance of the system and improve the performance of the heterogeneous mixed memory platform.

Description

technical field [0001] The invention belongs to the technical field of hybrid memory, and in particular relates to a fast access optimization method and system for heterogeneous hybrid memory. Background technique [0002] With the development and use of big data and memory computing applications, the demand for memory capacity and performance is increasing, but the high cost of Dynamic Random Access Memory (DRAM) is one of the factors that affects memory capacity expansion. important factor. As a new type of media, non-volatile memory (Non-volatile Memory, NVM) has a faster access speed than mechanical hard disks, and its non-volatile characteristics have attracted more and more attention from the market. NVM Express is a scalable host control chip interface standard developed for enterprise and general client systems using PCI Express SSDs. NVMe provides a set of relatively complex data structures and transaction processing methods. Command distribution and processing a...
