1.7. About Performance¶

CPU¶
Central Processing Unit¶: A central processing unit (CPU), also called a central processor, main processor or just processor, is the electronic circuitry within a computer that executes instructions that make up a computer program. [1]
GPU¶
Graphics Processing Unit¶: A graphics processing unit (GPU) is a specialized electronic circuit designed to rapidly manipulate and alter memory to accelerate the creation of images in a frame buffer intended for output to a display device. [2]
ALU¶
Arithmetic Logic Unit¶: An arithmetic logic unit (ALU) is a combinational digital electronic circuit that performs arithmetic and bitwise operations on integer binary numbers. [3]
FPU¶
Floating-Point Unit¶: A floating-point unit (FPU, colloquially a math coprocessor) is a part of a computer system specially designed to carry out operations on floating-point numbers. [4]
TPU¶
Tensor Processing Unit¶: A tensor processing unit (TPU) is an AI accelerator application-specific integrated circuit (ASIC) developed by Google specifically for neural network machine learning, particularly using Google's own TensorFlow software. [5]
