- Abstract:
- High-definition (HD) video signal storage module is the core of electronic endoscope video storage. Herein a HD electronic endoscope video storage is designed based on serial advanced technology attachment (SATA 2.0) protocol, and cyclic redundancy check-32 (CRC-32) algorithm for error checking is used in the physical layer and link layer of high-speed data transmission protocol, aiming to avoid various of interferences and errors during the data transmission in the channels. Finally, Verilog logic is programmed to achieve CRC-32 codec for simulation test, and the verification test is performed on Kintex-7 development board platform. With the bit error rate less than 10-12 at the speed up to 250 MB/s, the designed HD video signal storage module based on FPGA which has a good market prospect meets the requirement for high real-time, high bandwidth and low bit error rate.
