High-speed serial bus storage device provided with multiple high-speed interfaces

Abstract

The invention discloses a high-speed serial bus storage device provided with multiple high-speed interfaces. The high-speed serial bus storage device is designed to solve the problem that data acquired at a high speed cannot be stored timely, a 10-gigabit Ethernet, a gigabit Ethernet and an RAPIDIO interface are provided in the design, and accordingly, interface butt joint with other data acquisition boards is facilitated. By means of the advantage of rich resources of FPGA (field programmable gate array) chip pins, read-write operation is performed on 16 eMMC (embedded multimedia card) chips in parallel, and the read-write speed of a whole board is increased. The eMMC chips are selected as the storage chips, and the reliability of data of the whole board is guaranteed by means of the high-reliability characteristic of the eMMC chips. The eMMC chips follow uniform interface standards, and upgrading of the capacity and the speed of storage equipment can be easily completed under the condition that other hardware is not changed with the development of an eMMC technology.

Description

technical field [0001] The invention belongs to the technical field of digital signal processing, in particular to realizing a high-speed memory board based on an eMMC memory chip by using FPGA. Background technique [0002] With the rapid development of information science and technology, in the field of modern real-time signal processing, in order to obtain more accurate and effective information, it is necessary to obtain a large amount of data for processing, and the former high-speed data acquisition system has been used in radar, sonar, image processing, voice It is widely used in identification, communication, transient signal testing and other fields. A large amount of data is generated when the sensor array works, and the parallelism of the data is very real-time, so high-speed storage devices are needed to store the data. [0003] At present, most data storage systems are traditional disk array RAID. Since the invention of disk array RAID, its storage capacity and...

Problems solved by technology

[0003] At present, most data storage systems are traditional disk array RAID. Since the invention of disk array RAID, its storage capacity and reliability have been continuously improved. However, this disk array RAID itself has some disadvantages: slow read and write speed : The traditional disk array RAID adopts the high-speed rotating head of the disk as the data reading method, so the addressing time is long and the reading and writing speed is slow; the stability is low: the mechanical structure of the traditional disk array RAID causes the wear of the magnetic head and the deformation of the cantilever, and When the disk array is subjected to vibration, its working performance will be unstable, and it is not applicable under harsh environmental conditions: high power consumption: the mechanical rotation of the disk and the radial movement of the magnetic head in the traditional disk array RAID will be to a large extent The power consumption of the disk array increases

However, since NANDFLASH chips do not have a unified interface specification standard, issues such as ECC verification, bad block management, and load balancing must be considered when using them. To achieve stable and reliable data storage, there are many disadvantages in terms of complexity and resource consumption.
