When asked about how a central processing unit works, you might say it’s the brain of the computer. It does all the calculations on math and makes logical decisions based on certain outcomes. However, ...

This paper presents an instruction set simulator of a 32-bit CPU and explains its use in embedded software development. Interaction of the ISS with transaction level model of a complex peripheral ...

For an old CPU, finding all the valid instructions wasn’t very hard. You simply tried them all. Sure, really old CPUs might make it hard to tell what the instruction did, but once CPUs got illegal ...

You've probably heard the acronym CPU lots of times when you went out hunting for a laptop or desktop computer to buy. Quite often, the type of CPU in the device will be mentioned as part of the specs ...

This paper presents an instruction set simulator of an 8-bit, MCS-51 compatible CPU core, and shows how to use it in embedded software development process; Method to control and debug CPU using ...

Instruction Level Parallelism means executing multiple instructions or pieces of instructions at the same time to make the computer run faster. Computers have hit the parallelism wall. This paper will ...

Continuing his reverse-engineering of the Intel 8087, [Ken Shirriff] covers the conditional tests that are implemented in the microcode of this floating point processing unit (FPU). This microcode ...
