Increasing Microblaze Cache Size to 128kB

[20801700]

Hi everyone

Is it possible to increase Cache size to 128kB or even higher(256kB) in Microblaze? If it is possible, how?

Note: I know it seems like a basic question but I failed to find any answers or even find anyone else asking this question, If this is discussed before, please just give me a link to the referred discussion.

If you double click the microblaze in ipi you can config the cache size here

Cache size options are limited to 64kB in IP core generation settings, are there any ways to increase this size to 128kB?

Hi,

There is currently no possibility to increase the cache size beyond 64kbyte.

You could look at SystemCache IP for having a L2 cache (32kbyte-512kbyte) which could help if your external memory accesses are too slow.
