1. 解释为什么需要启用指令缓存(icache) 指令缓存(I-Cache)是CPU内部的一种高速缓存,用于存储最近被CPU读取过的指令。启用指令缓存可以显著提高程序的执行效率,因为它减少了CPU从较慢的存储器(如Flash或RAM)中读取指令的次数。对于性能要求较高的应用,如实时控制系统、嵌入式系统等,启用指令缓存是优化系统性能的重要...

The cache must be invalidated before being enabled. The method for this is implementation-defined. In some cases, invalidation is performed by hardware, whereas in other cases it is a requirement of the boot code. CMSIS- has added a specific instruction cache API to support these operations ...

Yes, I think !RISCV_ISA_EXT_ZICBOM didn't suffice enought, at less, in the case of Andes cores, there is a situation where only Data Cache (D cache) CMO is supported, and Instruction Cache (I cache) CMO is not supported. I need to update my perspective. I believe that CBOM_{I...
I don't think I explained myself very well, I'm assuming that the readouts are correct and there are zero cache misses however I want each iteration to be comparable on the number of data and instruct...
When adding any item to a cache configured to use a database as a backing store, the item's type must be serializable. The class implementing the ICacheItemRefreshAction interface must be serializable when using a database as the backing store. For more information about serialization, see ...
The class to be executed is the first top-level class found in the source file. It must contain a declaration of the standardpublic static void main(String[])method. The compiled classes are loaded by a custom class loader, that delegates to the application class loader. This implies that ...
