Question

I'm using a ARM7 device without any NEON floating point arithmetic hardware capabilities, so for my project I'm having to write in Assembly, I already have a multiplier working, is there any why I could calculate inverses quickly?

Was it helpful?

Solution

Will GCC software floating-point library be good for you? You'll find the assembler routines for floating-point division under libgcc/config/arm.
