摘要
以硬件直接实现固定的Flash编程操作是片内及片外Flash控制的常用方法。文中提出的双模式Flash控制器以Flash硬核模型为基础,组合了硬件直接实现硬核的编程操作和软件控制硬核的编程信号两种模式,实现了能以较快速度和较简单驱动控制Flash的逻辑和能以较高灵活性控制Flash的逻辑。两种模式使得Flash控制器具有一定的灵活性和快速实现性,其设计模式能适应更多Flash模型。
It is the common method to implement the fixed programming operations of a flash core in a chip or a flash chip in hardware. Based on the model of a flash core, the dual - mode flash controller combined the control mode that implementing the programming operations of a flash core absolutely in hardware and the control mode that managing the programming signals in software. The combination method made the flash controller work with higher speed and simple driver or work more flexibly. The dual - mode flash is more flexible and can be implemented quickly. Its design method can suit for more flash core models.
