Why are there only four registers in the most common CPU (x86)? Wouldn't there be a huge increase in speed if more registers were added? When will more registers be added?

I'm trying to wrap my head around some details about how floating point math is performed on the CPU, trying to better understand what data types to use etc.
I think I have a fairly good understanding of how integer math is performed. If I've understood correctly, and disregarding SIMD, a 32-bit…

Hi all,
I'm interested in knowing how GCC differs from Intel's ICC in terms of the optimization levels and catering to specific processor architecture. I'm using GCC 4.1.2 20070626 and ICC v11.1 for Linux.
How does ICC's optimization levels (O1 to O3) differ from GCC, if they differ at all?

Hello,
I was just wondering what other CPU architectures are available other than INTEL & AMD. So, found List of CPU architectures on Wikipedia.
It categorizes notable CPU architectures into following categories.
Embedded CPU architectures
Microcomputer CPU architectures
Workstation/Server…

Hi !
In Crypto communities it is common to measure algorithm performance in cycles/byte. My question is, which parameters in the CPU architecture are affecting this number? Except the clockspeed ofcourse :)
