T4241 Power calculation

[Har_ika30]

Hi all,

I am using T4241 processor in my design. It has 12 cores, but i will be using only 4 cores.

In datasheet, VID core power mentioned based on 12 cores usage, but i need VID power for only 4 cores usage. I will be putting other cores in power down mode.

Can anyone suggest how to calculate the power for T4241 with 4 cores enabled?

Thankyou

There is T4081 part, this has 4 cores. I guess if you require only 4 cores then this is the part number you should be choosing.

has the link for T4160.pdf
Refer "Table 9. T4081 Power dissipation for rev 2 silicon with Altivec power-gated off1" for power numbers.
