Cache configuration and NoC tracing

[Otávio Alcântara]

Hello,

   I would like to know how to setup the cache parameters. I've searched the files but I didn't find the cache device implementation.

   Besides that, I'm wondering if it is possible to trace the NoC activity. I mean to register the content of each transmitted message and its transmission and reception timestamps.

Best regards,

Otávio Alcântara

Hello Otávio,

You can setup cache parameters in <proc>_block.ac or <proc>_nonblock.ac (depending if you are using blocking or nonblocking interfaces). 

For instance: 

File: mips_block.ac declares instruction and data caches using the following commands:

ac_icache   IC("2w", 64, 8, "wt", "random");

ac_dcache   DC("2w", 64, 8, "wt", "random");

Parameters: Associativicy, number of blocks, words per block, write policy, replacement policy

The globlal_report.txt file generated after simulation contains some information about NoC statistics (requests, hops, packets per port, etc). But if you want 

to trace NoC activities, you can set the NOC_DEBUG flag at defines.h file. If can also add new printfs at the tlm_node.cpp, tlm_noc.cpp or wrappers_noc.cpp files. 

Liana.
