1.2. Feature Description
The Nios II flash accelerator provides a small fully-associate cache where both its line and cache sizes are user-configurable. The cache is constructed from registers. Standard Nios II cache management instructions such as flushi and initi can be used to flush or initialize the flash accelerator cache. The flash accelerator supports sequential instruction pre-fetch to improve performance over sequential instruction execution.
