Abstract

The present invention relates to the technical field of hybrid memory, and provides a heterogeneous hybrid memory fast access optimization method and system. The method includes: optimizing the command processing overhead of the NVMe protocol; after optimizing the command processing overhead of the NVMe protocol, when the command When starting up, use the Endpoint to poll the command queue; use the tracking bit content in the polling receiving buffer to test whether the DRAM load has arrived or not. The change of the tracking bit indicates the completion of the read command, thereby solving the NVM memory access problem. The problem of mismatching the speed of DRAM memory access can quickly access NVM memory on the heterogeneous hybrid memory platform based on NVM extended system memory, improve the overall memory access performance of the system, and thus improve the performance of the heterogeneous hybrid 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...
