IDE接口时序和最全的接口定义，通过它可以实现硬盘的扇区读写-IDE interface timing and the most comprehensive interface definition, it can be achieved by sector hard disk read and write

用verilog hdl写的Norflash控制器，可实现单字节读写，扇区擦除。-Norflash controller edit by Verilog hdl,it can read or write by Byte,or erase the sector.

sdhc卡spi扇区读verilog例程。包含sdhc卡初始化模块及一个扇区读模块，扇区读完数据放在一个fifo中缓存，为之后的工作做准备，可以集成到自己的项目中。已经在闪迪8Gsdhc卡上亲测成功-sdhc card sector read spi verilog routine. Initialization module and a read module contains sdhc card sector, the sector read data in a cache fifo in
