Arm7 or PC104 or something else

Started by Robert Gush September 24, 2004
Hi,

We have to tackle a new job that is going to use VOIP. I am wondering
whether the ARM7 series from Philips would be up to the job or if it
would be better to go the PC-104 route.

The plus points on a PC-104 system are:

a) Ethernet interface
b) OS such as linux available
c) Mass storage (Comapct Flash etc) available

The plus points for the ARM:
a) A lot of fun writing the code...

Can you give any further insight please?

Regards

Robert

You can use something like the following: http://www.arcom.com/pc104-xscale-viper.htm a ARM based PC 104 SBC, then you have both. PC 104 is basically the ISA bus in a different form factor. One can concievably use almost any CPU on the PC104 bus. Using an ARM7 based MCU with a built in ethernet controller will probably be a better choice than using the Philips ARM. You probably will be able to get VOIP code for the ARM in the form of a reference design based on an ARM + Ethernet MCU. Regards Anton Erasmus

you could check EP9301 from Cirrus, it has build in Ethernet and it's more capable than LPC, the development board comes with prebuild Linux and WinCE on CD Best regards Tsvetan --- PCB prototypes for $26 at http://run.to/pcb (http://www.olimex.com/pcb) PCB any volume assembly (http://www.olimex.com/pcb/protoa.html) Development boards for ARM, AVR, PIC, and MSP430 (http://www.olimex.com/dev)
Have a look at Freescale 56800 series.
These processors called hybrid DSP.
A lot of code included in their free compiler with IDE and code wizard.
