There was a time when the clock speed of a CPU was the only thing people were talking about. Back at the turn of the century, Intel and AMD locked horns in a race to release the first 1GHz desktop CPU ...

A new LLVM patch has added V_FMA_F32, a 3-operand fused multiply-add (FMA instruction) and introduced the VOPD3 instruction ...

The fundamental sequence of steps that a CPU performs. Also known as the "fetch-execute cycle," it is the process whereby a single instruction is executed. The first half of the cycle transfers the ...

How to validate an application on a RISC-V processor with custom instructions, analyze the application execution, and optimize the custom instruction implementation and its documentation. A RISC-V ...

The processor we will be considering in this tutorial is the MIPS processor. The MIPS processor, designed in 1984 by researchers at Stanford University, is a RISC (Reduced Instruction Set Computer) ...

For more than three decades, modern CPUs have relied on speculative execution to keep pipelines full. When it emerged in the 1990s, speculation was hailed as a breakthrough — just as pipelining and ...

Designing a µP isn't very difficult. Designing a µP that executes the same instruction set as an existing device, but doesn't copy that device's circuitry or microcode, is far trickier. It's still ...
