Problems solved by technology

[0003] As authorized announcement number is the disclosed disk array controller of CN103853498A, although it has realized flexible and convenient to use, safety and reliability are high, but the problem that existing disk controller still exists does not solve: the read-write efficiency of disk controller is relatively low. low, and the anti-interference ability of the disk controller is poor, which affects the service life of the disk controller, so we propose a disk controller

Abstract

The invention discloses a disk controller, which comprises a first mainboard, a second mainboard and a third mainboard, and is characterized in that the first mainboard comprises a command analysis module, a UDMA mode selection module, a dual-clock generator and a clock switching module; the second mainboard comprises a CPU, a main control interface controller, a flash memory controller and a cache module; and the third mainboard comprises an SRAM controller, a data buffer area, a register controller, a configuration and state register, a sub-channel controller, an ECC hardware error correction logic, an inspection module, an out-of-band data processing module and an NAND flash memory interface. According to the disk controller, the first mainboard, the second mainboard and the third mainboard are arranged, the read-write efficiency of the disk controller is effectively improved through division cooperation among the first mainboard, the second mainboard and the third mainboard, the workload of each mainboard is reduced through the arrangement of the first mainboard, the second mainboard and the third mainboard, therefore, the working loss of each mainboard is reduced, and the service life of the disk controller is further prolonged.

Description

technical field [0001] The invention belongs to the technical field of automatic control, and in particular relates to a disk controller. Background technique [0002] The disk is the main storage device on the periphery of the computer system. At present, the read and write control of disk data must rely on the standard peripheral interface of the computer system and the computer operating system. The computer communicates with the disk through a standard peripheral circuit interface connected to its bus. The designer writes a software driver that the computer can execute to configure the disk, and then the computer organizes the storage and reading of disk data by running the driver. There are still various problems with various disk controllers. [0003] As authorized announcement number is the disclosed disk array controller of CN103853498A, although it has realized flexible and convenient to use, safety and reliability are high, but the problem that existing disk contr...
