OMAP L138 power spreadsheet: "baseline" and "activity" definition

Hi,

I would like to ask some questions with L138 power consumption.

CLKIN < 24MHz

In OMAP L138 power consumption spreadsheet CLKIN is fixed at 24MHz.

On page 208 of SPRUH77, OMAP-L138 C6-Integra DSP+ARM Processor Technical Reference Manual

, §10.2, P_dynamic is shown to be proportional with frequency:

P_dynamic = C × U² × Frequency

Therefore, although the spreadsheet doesn't allow entering lower CLKIN values such as 12 or 16MHz, can we just use simple division (/2 when CLKIN=12M, /1.5 when CLKIN=16M) to obtain power consumption when a lowering CLKIN is used?

Activity VS Baseline

In power consumption spreadsheet we see "Activity" and "Baseline" rows.

In §10.2 Power Consumption Overview of SPRUH77, OMAP-L138 C6-Integra DSP+ARM Processor Technical Reference Manual we see P_total consists of P_dynamic and P_static.

Does there exist a correspondence such that:

Activity ↔ P_dynamic

Baseline ↔ P_static

?

However, there are also evidences disagreeing with this. When the button "Typical 300MHz" is pressed, the baseline power rises from "standby" button values:

CVDD: 16.6(standby) ↑ 98.2(300MHz)

Total:   35.3(standby) ↑ 116.9(300MHz)

According to definition P_static = f(leakage), if leakage is unchanged, p_static is also unchanged. If baseline = P_static, then baseline is also unchanged. I have no knowledge on whether ↑ CPU frequency to 300MHz also ↑ leakage so I cannot infer which has caused baseline ↑. However, if ↑CPU frequency  does not cause ↑leakage, then from the increase of baseline from standby mode to 300MHz mode, we could conclude that baseline ≠ P_static.

Could anyone clarify on the definition of "baseline" and "activity"?
