In high-speed real-time or non real-time signal processing systems, the use of mass memory for data cache is an indispensable part. It is also one of the focus and the difficulties in the realization of the system. Using the traditional method, the simulation will consume a lot of time, which would greatly reduce the efficiency of software design. To save time and resources, a simplified simulation model is put forward. Based on this module, a number of control signals are added to make the design more flexible. The paper is based on the overall idea of the design and taking a FLASH device as an example, the paper fully describes this idea. The design has proved that this is a more efficient method. The idea reflected can be widely used in the large-scale embedded system.
