Problems solved by technology

Conventional LA (reference model TL2236, reference unit price 8000RMB) system memory is only 72Mbit, and the captured data can only capture 100-200ms. TL3234B+ / LA3036B reference unit price 27000 / 56000RMB) This kind of LA can capture the entire system startup process, but because it contains user data, it needs to classify and identify data during analysis, and the workload is huge

Embodiment Construction

[0015] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0016] Such as figure 1 As shown, the present invention provides a kind of Flash data analysis filter, connects FPGA platelet in series between flash memory and LA (logic analyzer), FPGA is programmed, circuit design is described by VHDL hardware description language, and then through flash memory ALE (address command line) or CLE (flash command line) for triggering.

[0017] Programming the FPGA includes the following steps:

[0018] Step 1: Set filter data and only keep commands;

[0019] Step 2: Set to retain a fixed data length;

[0020] The trigger condition is when the rising edge of ALE or CLE.

[0021] For the discarded data packets that do not meet step 1 and step 2, the data that meets step 1 and step 2 are connected to LA (logic analyzer) through the analysis filter board for manual data analysis. The manual analysis and judgme...

Abstract

The invention relates to the technical field of a flash and in particular to a Flash data analysis filter. The invention provides the Flash data analysis filter. An FPGA (Field Programmable Gate Array) small plate is connected between the flash and an LA (Logic Analyzer) in series; an FPGA is programmed; a circuit design is described through a VHDL (Vhsic Hardware Description Language); and then triggering is performed through an ALE (Address Line) or a CLE (Flash Line). According to the Flash data analysis filter, the workload during analysis of data can be decreased, the use cost is reduced;because a data package which is retained with a specific length can be set, user data is greatly reduced and the structure is simple.

Description

technical field [0001] The invention relates to the technical field of flash memory, in particular to a flash data analysis filter. Background technique [0002] In the flash memory industry, data analysis is required for product problems. The conventional way is to connect flash memory through LA ( figure 2 ), capture data, and then perform data analysis, but LA itself is only a device for data capture, and it cannot distinguish data, so the captured data includes system data (system data includes system operation commands, addresses, and boot data) and user data (user data includes file system partition tables, user storage files). Conventional LA (reference model TL2236, reference unit price 8000RMB) system memory is only 72Mbit, and the captured data can only capture 100-200ms. TL3234B+ / LA3036B reference unit price 27000 / 56000RMB) This kind of LA can capture the entire system startup process, but because it contains user data, it needs to classify and identify data du...
