The thermal management in VPU=352MHz for i.MX6Q

[yuuki]

Dear all,

We want to operate VPU at 352MHz.

In this case it is necessary to change the VDD_SOC_IN voltage. (1.35V < VDD_SOC_IN)

We have some following questions

(1)

How much does the heat value at VPU=352MHz increase in comparison at VPU=264MHz?

(2)

If VDD_SOC_IN is set to 1.35V or less and VPU is set to 352MHz, what will happen?

May I have advice?

Best Regards,

Yuuki

Hi Yuuki

1. I am afraid such data is not available, just as rough estimation one

can expect increase by factor 1.7=(352/264)**2, assuming current is

proportinal frequency.

2. vpu will not work as expected, for example produce bad image quality

Best regards

igor
