### 1.2 Performance Analysis
#### 1.2.1 CPU Usage
For both bare-metal and OS environment, you can measure the CPU Usage with macro `__cpu_usage__()` for a given code segment as long as it is executed repeatedly.
**Syntax**
```c
__cycleof__(<Iteration Count before getting an average result>, [User Code, see ref 1]) {
//! target code segment of measurement
...
}
```
Here, [**ref 1**] is a small user code to read the measurement result via a local variable `__usage__`. This User Code is optional. If you don't put anything here, the measured result will be shown with a `__perf_counter_printf__`.
##### **Example 1: the following code will show 30% of CPU Usage:**
```c
void main(void)
{
...
while (1) {
__cpu_usage__(10) {
delay_us(30000);
}
delay_us(70000);
}
...
}
```
##### Example 2: Read measurement result via `__usage__`
```c
void main(void)
{
...
while (1) {
float fUsage = 0.0f;
__cpu_usage__(10, {
fUsage = __usage__; /*< "__usage__" stores the result */
}) {
delay_us(30000);
}
printf("task 1 cpu usage %3.2f %%\r\n", (double)fUsage);
delay_us(70000);
}
...
}
```
NOTE: The `__usage__` stores the percentage information.
### 1.2 Timestamp
#### 1.2.2 Cycle per Instruction and L1 DCache Miss Rate
For **Armv8.1-m** processors that implement the **PMU**, it is easy to measure the **CPI** (Cycle per Instruction) and **L1 DCache miss rate** with the macro `__cpu_perf__()`.
**Syntax**:
```c
__cpu_perf__(<Description String for the target>, [User Code, see ref 1]) {
//! target code segment of measurement
...
}
```
Here, [**ref 1**] is a small user code to read the measurement result via a local **struct** variable `__PERF_INFO__` . This User Code is optional. If you don't put anything here, the measured result will be shown with a `__perf_counter_printf__`. The prototype of the `__PERF_INFO__` is shown below:
```c
struct {
uint64_t dwNoInstr; /* number of instruction executed */
uint64_t dwNoMemAccess; /* number of memory access */
uint64_t dwNoL1DCacheRefill; /* number of L1 DCache Refill */
int64_t lCycles; /* number of CPU cycles */
uint32_t wInstrCalib;
uint32_t wMemAccessCalib;
float fCPI; /* Cycle per Instruction */
float fDCacheMissRate; /* L1 DCache miss rate in percentage */
} __PERF_INFO__;
```
For example, when insert user code, you can read CPI from `__PERF_INFO__.fCPI`.
**Example 1: measure the Coremark**
```c
void main(void)
{
init_cycle_counter(false);
printf("Run coremark\r\n");
#ifdef __PERF_COUNTER_COREMARK__
__cpu_perf__("Coremark") {
coremark_main();
}
#endif
while(1) {
__NOP();
}
}
```
The result might look like the following:

3. Grant of Patent License. Subject to the terms and conditions of
this License, each Contributor hereby grants to You a perpetual,
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
(except as stated in this section) patent license to make, have made,
use, offer to sell, sell, import, and otherwise transfer the Work,
where such license applies only to those patent claims licensable
by such Contributor that are necessarily infringed by their
Contribution(s) alone or by combination of their Contribution(s)
with the Work to which such Contribution(s) was submitted. If You
institute patent litigation against any entity (including a
cross-claim or counterclaim in a lawsuit) alleging that the Work
or a Contribution incorporated within the Work constitutes direct
or contributory patent infringement, then any patent licenses
granted to You under this License for that Work shall terminate
as of the date such litigation is filed.
4. Redistribution. You may reproduce and distribute copies of the

(a) You must give any other recipients of the Work or
Derivative Works a copy of this License; and
(b) You must cause any modified files to carry prominent notices
stating that You changed the files; and

documentation, if provided along with the Derivative Works; or,
within a display generated by the Derivative Works, if and
wherever such third-party notices normally appear. The contents
of the NOTICE file are for informational purposes only and
do not modify the License. You may add Your own attribution
notices within Derivative Works that You distribute, alongside
or as an addendum to the NOTICE text from the Work, provided
that such additional attribution notices cannot be construed
as modifying the License.
You may add Your own copyright statement to Your modifications and
may provide additional or different license terms and conditions
for use, reproduction, or distribution of Your modifications, or
for any such Derivative Works as a whole, provided Your use,
reproduction, and distribution of the Work otherwise complies with
the conditions stated in this License.
5. Submission of Contributions. Unless You explicitly state otherwise,
any Contribution intentionally submitted for inclusion in the Work
by You to the Licensor shall be under the terms and conditions of
this License, without any additional terms or conditions.

*! to store the higher 32bits. When you are using the prototype from
