基于高速图像数据Flash存储阵列无效块管理

Invalid block management based on high- speed mass image data flash storage array

针对高速图像数据FPGA大容量存储的需求,提出了两种基于高速并行化Flash大容量数据存储结构的无效块管理策略,并对比了在不同应用环境下,基于超级块地址映射的无效块管理及基于位索引的无效块管理的优缺点,列出了两种方式的数据无效块列表资源占用情况和存储容量损耗。通过多个工程项目的验证,这两种无效快管理策略各有所长,满足高速并行化存储Flash阵列的不同应用环境。

According to the need of the high - speed mass image data storage base on FPGA,it is proposed that two kinds of invalid fast management strategy of the structure based on high - speed parallel Flash high - capacity data storage, and compares the ad- vantages and disadvantages of the invalid block management based on the super block address mapping and based on an index of in- valid block management in different application environment, lists the two ways of invalid data block list resource utilization and storage capacity loss. Through multiple validation of the project, the two kinds of invalid fast management strategy strengths and meet the high - speed parallel Flash storage array of different applications.
