Tool / method for Cache Performance Analysis
>> Unfortunately, We don’t have any tools to specifically benchmark the cache.
The ADSP-21569 hardware does, however, have performance monitors that can count the number of cache hits and misses that occur. You could use these to find out how often instruction cache (I-cache) misses occur in your application when code is placed in external memory.
Please find the attached example that shows how the performance monitors can be used to count cache hits and misses in the various caches. To count Instruction Cache hits and misses, check codes from line number 252. We can use this technique in our sample code to see how the instruction cache is performing in application.
