That is one that I can definitely help with :-) You can find the ARM architecture reference manual that includes all ASM instructions for the ARM7 and other ARM cores. Now, if you really want to torture yourself and program an ARM7 like the lpc2378 in ASM, this 1138 page manual should provide all the info

hey... can anyone tell me how to interface any ARM processor to the network card?I am currently working on ARM 7(lpc2378)processor.I want to use the ethernet port of the same. thanks...
The Olimex board is used by IAR. If you install IAR Embedded Workbench for ARM you will find many examples of USB with the lpc2378-STK.
you can use lpc2378 from NXP - it has MMC driver and ethernet. check MCB2370 Evaluation Board from Keil
Buy an mb2300 board from keil. After that examine the arm architecture and the datasheet of lpc2378 (NXP chip) ROUGHLY. Dont waste time by diving in deeply. And begin to examine sample programs. After that put a project infront of yourself for TRADING PURPOSE (for manufacturing. and for selling). Life is not so long, go on with a serious project. D
Use AVR atmega series ,they are perfect choice in any view that you see. I recomment you look at ARM7 32 bit micros Like as philips LPC2364,lpc2378 for better and higher needs.
