Cache Optimization in DSP and Embedded Systems
A cache is an area of high-speed memory linked directly to the embedded CPU. The embedded CPU can access information in the processor cache much more quickly than information stored in main memory. Frequently-used data is stored in the cache.
There are different types of caches but they all serve the same basic purpose. They store recently-used information in a place where it can be accessed very quickly. One common type of cache is a disk cache. This cache model stores information you have recently read from your hard disk in the computer’s RAM, or memory. Accessing RAM is much faster than reading data off the hard disk and therefore this can help you access common files or folders on your hard ...
