Today is the first day of a 3-day training on an embedded CPU from Texas Instrument. In class I asked a lot of questions as usual, and in fact, that processor is pretty slick and loaded with tonnes of interesting features.
Quite thrilled because this skill can be used in Singapore also. Ha! :P

What processor is that? MSP series? What's the power consumption like? Datasheet?
OMAP 1710, a RISC processing platform because it contains an ARM9 and a C55XX DSP chip. The power consumption is quite amazing: 0.1uA/MHz and can get 0.6mA during sleep mode @ 1.3V. IXP don't think can make it so low. :P
Are you sure about the figures? Sounds really great. If I use it at 8MHz, then power consumption at 1.3V is just 1.04uW. Unbelievable. :)
Do you have the datasheet? Please send it to me if it's not confidential stuff.
Thanks. :)

Ok, correction:
This processor can switch off modules/clocks that you don't need, so the power consumption rates are quoted according to modules:
Clock module @1.3V 31uA/MHz
Traffic controller @1.3V 91uA/MHz
ARM 300uA/MHz @ 1.5V (DSP idle)
ARM idle, DSP 300 uA/MHz @ 1.3V
So roughly when in full use it can be somewhere like 600-700 uA/MHz if you use both cores
In Sleep modes:
Deep sleep (all clocks off except one 32KHz power management module clock) 200 uA
These figures are from TI, so should be right. I have the datasheet, but it is huge, 12MB, you have ftp server open so that I can upload it? Or you can try to download it from TI website.
Did you find it on their website? I couldn't find the link.
Otherwise, just send it to my gmail account. You know where that is. :)
FTP seems to have been blocked by the school or something. People can't seem to upload files.
Check your email. ;)
