What is a Core Processor?

If you thought about collaborating with Phison for your SSD project, you may have heard the term “core processor.” But what exactly is a core processor? And what does it do?

For a Phison SSD, the core processor is one part of the SSD controller.

During a data read/write workflow, data passes through the data buffer, core processor, flash controller, security engine, and ECC engine. The core processor plays a vital role in optimizing data allocation during command processing and is crucial to ensuring an efficient and fast read and write performance.

The core processor’s primary function is to arrange the priority of command tasks, so the SSD performance is as good as possible.

The core processor manages a series of read and write commands for the SSD. For example, when the host issues a read command, this command needs to temporarily assume a higher priority than other commands. The core processor briefly runs other processes in the background or suspends them. After implementing the read command thoroughly, the core processor will return to do the previous string of issued commands. This is how Phison’s developers use the core processor to ensure that your SSD performs at its best.
