Just picked up one of these ARM Cortex-M3 LPC1768 mini boards from eBay. It\'s basically a breakout board.
Is there any difference between the following instruction (besides flags affection)? 开发者_运维知识库ADDR6, SP, #0xDC
If I understand it correctly, because ARM instructions are 32 bits long they can only hold so many bits of immediate value. What I\'m trying to do is vmov.f32 s0, #0.0, and I get \"immediate out of ra
I\'m writing ARM assembly code that at some point has to set a single bit of a register to 1. This is best done of course via \"register-or-bitmask\" method. However, according to ARM documentation, t
Quoting from the ARM MRC documentation, MRC{2}<c><q> <coproc>, #<opc1>, <Rt>, <CRn>, <CRm>{, #<opc2>}
I\'m trying to optimize an image format conversion on iOS using the NEON vector instruction set. I assumed this would map well to that because it processes a bunch of similar data.

I am looking to create a native build of GCC for an ARM system and I am running into some trouble. The build machine is i686-linux. Every tutorial I see tells me how to set up the actual cross c开发者
It is possible to re-express: i % m as: i & (m-1) where, i is an unsigned integer m is a power of 2 My question is: is the AND operation any faster? Don\'t modern CPUs support integer
