Abstract
To read out the data in data acquisition system, a program designed for a universal flash reading system has been introduced in this paper. FPGA is used as a main controller to operate on the FLASH, and USB 2.0 interface chip Cy7C68013A is used to achieve communication between the system and the computer. As for invalid blocks in the NAND Flash produced by SAMSUNG, mis paper comes up with a detecting and processing method for invalid block, which proves to be available in large data acquisition system as well.
A significance statement is not available in the OpenAlex record.
A contribution statement is not available in the OpenAlex record.
Method details are not available in the OpenAlex metadata.
Findings are not separately available in the OpenAlex metadata.
Limitations are not available in the OpenAlex metadata.
Application details are not available in the OpenAlex metadata.
