摘要

实现了一种基于电缆调制解调器的闪存存储系统。硬件方面，采用缓存和队列技术设计了flash控制器，通过设置简单的关联缓存实现对flash的突发读取，并通过FIFO队列实现对flash的异步写入。在软件方面，我们修改了MTD上的CFI，使闪存访问进程以中断的方式而不是连续查询的方式进行调度。性能分析和测试结果表明，该系统提高了闪存的访问效率和CPU的吞吐量，具有较高的稳定性和灵活的可配置性。该系统已应用于基于Godson-I CPU的电缆调制解调器。具有通用性，可用于相关的嵌入式系统。

A High Efficient Flash Storage System for Two-Way Cable Modem

A flash storage system based on cable modem is implemented. On the hardware hand, a flash controller is designed using cache and queue technology, and realizes burst read from flash by a simple set associative cache, and implements asynchronous write to flash by FIFO queue. On the software hand, we revise CFI on MTD so that flash access processes are scheduled by the way of interrupt instead of continuous queries. Performance analysis and test result show that the system improves access efficiency of flash and throughput of CPU, with a high stability and flexible configurability. The system has been used for cable modem based on Godson-I CPU. With generality, it can be used for correlative embedded systems.
