perhaps we should have some sort of standard that programs should conform to, to help save our poor batteries juice.

its possible to turn off second cpu right?

so for programs which DON'T utilise the second CPU, how feasable would it be to have these programs turn the second CPU off when they are ran, and back on when they are closed?

for example the NES emu, i dont think it utilises the second CPU, but to help save battery life, when its ran have it turn the second CPU off to keep batteries going ok?

is this a good idea or am i talking garbage?

i think it's the normal way of evolution of programs to turn on and off what they need and set the cpu freq to the minimum by themselves

Now that the code is available im sure devs will be making use of it anyway

​

well from what ive been reading, both processors are constantly on and running at 200mhz or more all the time, which is accounting for the silly battery life.

perhaps a firmware upgrade which turns off the second CPU by DEFAULT, and then programs which use the second CPU to turn it on when needed?

i think that would be better

 

[nik166]

if such a firmware upgrade don't come, someone else will make it someday!

 

[mrsnature]

AFAIK you can't turn off the second processor. And nik166 is right, programs should already turn off anything they don't need, what you are suggesting is more 'useful advice' for programmers, not a 'standard to conform to'

 

[nik166]

AFAIK you can't turn off the second processor.

​

have you tried the overcklocking utility ?

Be careful, you'll get flamed... You don't know what you're talking about, and nothing is more annoying to devs that getting advice from people who do not know about programming

The 940T is turned off by default in the retail firmwares it seems.

Not me, I'm a nice dev. I'm instructive.

But I'm also one of the least knowledgeable.

Knowledge is power, and power corrupts.

​

by the firmware? i thought the video player was using it?

​

Soooo true.

how do you know wether or not i know what im talking about?

 

[nickspoon]

Because people who know what they're talking about use capital letters.

 

[abigsmurf]

Yeah I'm confused. GPH said both CPUs were enabled by default even though the software on it only uses one. As far as I'm aware the magiceyes chipset doesn't have an auto speed-step-type function so unless it's told otherwise there should still be a lot of power running through it.

 

[nik166]

​

you should have used capital letters to say that

EDIT: Whatever, I assumed he meant a capital letter at the beginning of each sentence, but he could have been being sarcastic and saying that PEOPLE WHO TYPE IN ALL CAPS know what they are talking about....

 

[RiX0R]

LOL you just pwnd yourself. It's called the rule where you start each new sentence with a capital letter. Wow, just WOW.

​

I'm guessing he meant "People who [...] use Capital Letters". Or perhaps "CAPITAL LETTERS".

In any case, who cares, and this thread is void.

​

he used ONE capital letter,
like rixor said (perhaps he has a better ability for understand things that you ) i meant CAPITAL LETTERS


but let's go back to the original subject h34r:

 

[Series-8]

shure the 2nd core isn't just running in a NOP loop or getting a HLT instruction all the time.
(on a proper x86 there is a power saving shutdown when the proc. executes certain instructions like that, ARM I think should act even more efficiently)

Err whatever the nmeonic for ARM would be.
