3.1.2 FLC - Fast Local Copy (Image Download Acceleration)

OptiFlash supports a Fast Local Copy (FLC) engine for image download acceleration, during startup or run time, to enable code download along with CPU execution in parallel. It redirects the CPU access to Flash when the copy is in progress and redirecting the access to SRAM when the content is in valid in SRAM, as shown in Figure 3-2. This enables CPU to execute immediately without waiting for the copy to complete. The operation is transparent to CPU, and results in reduced startup time, in order to meet startup time goals similar to an embedded flash and also provide dynamic overlay for run time performance.
