Field programmable gate array (FPGA)-based serial advanced technology attachment (SATA) master controller

Abstract

The invention provides a field programmable gate array (FPGA)-based serial advance technology attachment (SATA) master controller, and aims to realize the read-and-write control of an SATA interface hard disk by utilizing an FPGA device efficiently and conveniently. The FPGA-based SATA master controller comprises an SATA physical layer implementation module, an SATA link layer implementation module, an SATA transmission layer implementation layer, an SATA application layer implementation module and the like. Compared with the conventional design, a higher level of logic encapsulation is realized; a simpler operation interface is provided for a user; and the read-and-write control of the SATA interface hard disk can be realized by operating simple interfaces in the forms such as first-in first-out (FIFO), a static random access memory (SRAM), a register provided by the invention by the user.

Description

technical field [0001] The invention belongs to the field of electronic information, and relates to computer peripheral equipment and key components, in particular to a controller for a safe storage device used in products such as computers. The present invention uses a Field Programmable Gate Array (FPGA, Field Programmable Gate Array) chip as an implementation platform, constructs logic through a hardware description language (HDL, Hardware Description Language), and realizes storage devices ( Such as SATA interface hard disk) read and write control. Background technique [0002] With the development of high-speed serial data transmission technology in recent years, the interconnection form of various peripheral devices inside the computer has gradually transitioned from parallel bus form to serial interconnection. For example, the PCI bus was gradually replaced by PCI Express. Disks, including traditional mechanical disks and solid-state disks (SSDs), which have develop...

Problems solved by technology

[0004] The existing FPGA-based SATA protocol main controller IP core models are limited, and generally only implement the transport layer of the SATA protocol. The user interface left to the user is still relatively complicated, and the user needs to understand the SATA protocol and disk-related technical specifications. It can be used effectively after a certain amount of learning, which is not conducive to the rapid use of FPGA by ordinary users to realize the read and write control of the disk
