Problems solved by technology

However, the existing non-ARM core SoC application verification board cannot carry out application verification for LSoCAM0201 due to limited design functions and low performance. The functional block diagram of the non-ARM core SoC application verification board is as follows figure 1 shown

First of all, the main frequency of non-ARM core SoC design is not high, generally below 200MHz, and the corresponding memory interface such as SDRAM only has an operating frequency of 100MHz or below, so only low-frequency parallel memory can be used, and it can only be designed with it in application verification. Corresponding low-speed storage implementation; secondly, although non-ARM core SoC also integrates some common interfaces, but limited by the operating frequency, the integrated peripheral interfaces are generally low-speed interfaces, and only low-speed interface applications can be designed in application verification; Finally, the integrated interface functions of non-ARM core SoCs are relatively single, and cannot be compatible with different operating modes or different operating frequencies. The corresponding application verification design is also relatively simple, and cannot be compatible with different operating modes.
