Message processing method and device of flash memory channel controller, equipment and readable medium

Abstract

The invention discloses a message processing method of a flash memory channel controller, which comprises the following steps of: receiving a read request message, and sending a memory address application message to a cache controller based on the read request message; executing a read operation based on the read request message, and judging whether a memory address is successfully applied to the cache controller or not; and in response to successful application of the memory address to the cache controller, executing a data transmission operation based on the memory address. The invention further discloses a message processing device of the flash channel controller, computer equipment and a readable storage medium. According to the method, a mode of applying for the memory address in advance is adopted, judgment on whether the memory address is successfully applied or not is added before data transmission, parallel processing of a read command and memory address application is achieved, memory address application time is saved, read time is shortened, and product performance is improved.

Description

technical field [0001] The present invention relates to the technical field of data transmission, and in particular, to a message processing method, apparatus, device and readable medium of a flash memory channel controller. Background technique [0002] The existing FCC (Flash channel controller, flash channel controller) process for implementing a command includes: [0003] The message is received and parsed by the LUN (Logical Unit Number), and the context is initialized according to the content of the message; [0004] If the flash channel controller needs to apply for a memory address (buffer) by itself, send a content address application request (request) to the cache controller (BM, Buffer Manager); [0005] The cache controller applies for a memory address and returns the applied memory address to the flash channel controller; [0006] The flash channel controller continues to execute the corresponding command according to the message content; [0007] After the e...

Problems solved by technology

This greatly increases the total time spent on processing requests by the flash channel controller, which has a greater impact on the clock cycle (Latency) required for the flash channel controller to fully execute an instruction, thereby affecting other key performance indicators of the product, such as IOPS (Input / OutputOperations Per Second, the number of read and write operations per second), bandwidth, etc.
