Quick Start Guide for the CMCC driver

This is the quick start guide for the CMCC - Cortex M Cache Controller module, with step-by-step instructions on how to configure and use the driver for a specific use case.The code examples can be copied into e.g the main application loop or any other function that will need to control the CMCC module.

Use cases

• CMCC basic usage

CMCC basic usage

This use case will demonstrate how to initialize the CMCC module.

Setup steps

Code

Add this to the main loop or a setup function:

struct cmcc_config   g_cmcc_cfg;
cmcc_get_config_defaults(&g_cmcc_cfg);
cmcc_init(CMCC, &g_cmcc_cfg);
cmcc_enable(CMCC);

Workflow

1. Enable the CMCC module

   cmcc_enable(CMCC); 

2. Initialize the CMCC to Data hit counter mode

   g_cmcc_cfg->cmcc_mcfg_mode = CMCC_DHIT_COUNT_MODE;
   cmcc_set_config(CMCC,&g_cmcc_cfg);
   cmcc_enable_monitor(CMCC);

Usage steps

Code

We can then get the count of Cache Monitor Event by

cmcc_get_monitor_cnt(CMCC);
