Embodiment Construction

[0013] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0014] Such as figure 1 As shown, the whole board has a total of 96 K9WBG08U1M NAND chips (each chip has a storage capacity of 4GB), and each group of 8 chips is a group of 12 groups, which are connected to two groups of NAND controller sub-modules on average; each NAND controller sub-module It is realized by a piece of XC4VLX60FPGA of Xilinx Company, on which 6 groups of NAND controllers are designed to read and write access to 48 pieces of NAND in parallel, such as figure 2 shown. Each NAND controller manages 8 pieces of NAND, and the 6 control signals (CE, ALE, CLE, RE, WE, R / B) of the 8 pieces of NAND are connected together, and the data lines (8bit×8=64bit) are separated independently , so as to achieve parallel access to 8 pieces of NAND (such as image 3 shown). The NAND controller sub-module realizes data exchange with the main cont...

Abstract

The invention relates to an NAND-based memory plate, and belongs to high-speed signal acquisition and storage and related fields thereof. The NAND-based memory plate comprises an NAND memory array, an NAND controller module, a digital signal processing (DSP) module and a main control module, wherein the NAND memory array is connected with the data output port of the NAND controller module; the input port of the NAND controller module is connected with the main control module; and the main control module is connected with the DSP module and a user-defined interface connected to external. The NAND-based memory plate realizes the parallel access and management of a plurality of NANDs through a field programmable gate array (FPGA), and greatly improves memory and read bandwidth by adopting a multilevel parallel access mode, so as to realize the technical indexes of the maximal memory capacity of 768GB of a veneer, the access band width of 1297 MB / s, and the veneer power consumption of 15W; and through real-time control of a DSP chip, the communication between an upper computer and an internal control module of a board is realized so that the board is easy to realize system integration.

Description

technical field [0001] The invention relates to a storage board based on NAND, which belongs to the field of high-speed signal acquisition and storage and related fields. Background technique [0002] High-speed and large-capacity data storage boards are mainly used in embedded applications that require large storage bandwidth and storage capacity in signal acquisition, such as continuous acquisition and storage of broadband signals in radar, electronic countermeasures and other application fields. In these applications, in addition to the need for high-speed data storage bandwidth and large data storage capacity, the volume and power consumption of the device should be as small as possible due to the application situation. At present, most data storage products use hard disks as storage media. The access bandwidth of a single disk body is only tens of megabytes / second, and although the disk array built from this can reach 300-400MB / s in bandwidth, the ensuing increase in vo...
