cycle count / CW10.6 for S12Z

[hiroyoshisuzuki]

Hi,

I'm sensor FAE but supporting about customer's question about CW10.6, now.

Customer would like to check a performance of S12Z CPU by CW10.6. I mean, cpu time.

Easy way is to count clock cycle by assembler list file. Is there any feature which can count the cycle counts?

I know, there is a disassembler function by right click the source file. But, the cycle count is always zero.

Do you know the way to show the cycle number?

25:		u64Test++;
00000058 08E030	[0]	LEA	X,(48,S)
0000005B 09E020	[0]	LEA	Y,(32,S)
0000005E 1F4050	[0]	MOV.L	(0,X),(0,Y)
00000061 1F4454	[0]	MOV.L	(4,X),(4,Y)
00000064 BB000000	[0]	JSR	0

And, It is good if there is calculation function of sum of specific code.

Best regardfs.

Hi Hiroyoshi-san,

Now, the Update 6 has been released.

To install it you need to launch Eclipse and click on Help + Install New Software ...

Select the generic:

    FSL MCU Eclipse Update Site - http://freescale.com/lgfiles/updates/Eclipse/MCU10_6_4/com.freescale.mcu.updatesite

to be sure you can run it 2 times.

After that you can launch the Help + Check for Updates too.

Under the installation, at then end you will see release notes under \CW MCU v10.6.4\MCU.

for instance:

Have a great day,
Pascal

Hi,

I'm using CW for MCU v10.6.4 + patch V10.6.5.

With this version I've created a project based on mc9s12zvml128.

In the project properties for the S12Z Disassembler you can select the Output options:

    Show Cycle Count for Each Instruction.

On my side it seems to be working.
