| 针对破片测速系统对数据存储速率快、可靠性高的要求，提出了基于流水线设计的数据快速存储方案和基于FPGA片内建立虚拟存储器来管理FLASH坏块列表的方法。
该方法有效降低存储系统的平均响应时间，将数据流的存储速率提高了近2倍；并且有效地屏蔽FLASH的坏块，保证了破片数据存储的可靠性。
试验表明：该方法使数据存储速率提高到2.4Mbytes/S，为原始速率的3倍。数据存储的可靠性为100%。 |

| Abstract: |
| As the fragment velocity measurement system for high data storage rate and reliability requirements, presents a fast data storage scheme based on pipeline design and establishes a virtual memory to manage the FLASH bad block list based on FPGA chip.
This method reduces the average response time and makes the data storage rate 2 times faster. Meanwhile, the virtual memory can manage the Flash bad block list easily and block bad blocks effectively, then ensure the reliability of the fragment data storage.
Test shows that the method improves the data storage rate raised to 2.4 Mbytes/S which is 3 times as original rate. The reliability of data storage is 100%. |
