3.1.1 RL2-Flash Cache

OptiFlash supports a Remote L2 controller (RL2) for caching that is customized for flash and application characteristics for optimized system performance. It can reduce external Flash access by up to 65-95% based on application profile(RL2 size allocated in the application). It acts as a Level 2 cache controller as it provides additional caching, specific to Flash storage, beyond CPU Core’s L1 caching. The cache is remote, that is, the actual cache memory can be part of any system memory. For example, on-chip memory (remote cache data storage memory), instead of a dedicated cache storage within the controller. User has flexibility to specify the size of cache based on target application needs.
