ALU on CPU and GPU: Types, Features and How They Work
WEBJun 17, 2021 · The ALU or known in Spanish as a logicoarithmetic unit are the units within a CPU or a GPU that are literally in charge of crunching numbers and therefore are responsible for all the mathematical calculations that are performed several billions of times per second in our PCs But how do they work, what types.
Arithmetic logic unit - Wikipedia
WEBIn computing, an arithmetic logic unit (ALU) is a combinational digital circuit that performs arithmetic and bitwise operations on integer binary numbers. [1] [2] This is in contrast to a floating-point unit (FPU), which operates on floating point numbers.

cpu - VPU vs FPU vs GPU vs ALU - Stack Overflow
WEBMar 4, 2018 · A GPU is a large collection of cores (each typically containing an ALU and an FPU) and some special units (used for graphics processing) that do not exist in VPUs and general-purpose CPUs. Most if not all real GPUs, however, are not VPUs because they do not support such powerful vector instructions.
