APU - Accelerated Processing Unit

​ An accelerated processing unit (APU) is a microprocessor that combines the central processing unit (CPU) with the graphics processing unit (GPU) on a single computer chip.

​ AMD created APU (accelerated processing unit) processors in 2011. They refer to AMD CPUs that have integrated graphics. While APU sounds like any normal computer chip, it actually is solely used by AMD like the brand name of the CPU/GPU combo chips they manufacture.

BPU - Brain Processing Unit

​ The BPU(Brain Processing Unit) is an embedded artificial intelligence processor architecture proposed by Horizon Technology.

CPU - Central Processing Unit

​ The Central Processing Unit (CPU) is the primary component of a computer that acts as its “control center.” The CPU, also referred to as the “central” or “main” processor, is a complex set of electronic circuitry that runs the machine’s operating system and apps. The CPU interprets, processes and executes instructions, most often from the hardware and software programs running on the device.

​ The CPU performs arithmetic, logic, and other operations to transform data input into more usable information output. While the CPU must contain at least one processing core, many contain multiple cores. A server with two hexa-core CPUs.

DPU - Deep learning Processing Unit

​ The deep-learning processor unit (DPU) is a programmable engine optimized for deep neural networks.

​ The DPU is released with the Vitis AI specialized instruction set, thus facilitating the efficient implementation of deep learning networks.

EPU

FPU - Floating-point unit

​ In general-purpose computer architectures, one or more FPUs may be integrated as execution units within the central processing unit.

GPU - Graphics Processing Unit

​ A graphics processing unit (GPU) is an electronic circuit designed to process images and accelerate the rendering of 3D computer graphics on consumer devices.

LPU

MPU

NPU - Neural network Processing Unit

​ A neural processing unit (NPU) is a microprocessor that specializes in the acceleration of machine learning algorithms, typically by operating on predictive models such as artificial neural networks (ANNs) or random forests (RFs). It is, also, known as neural processor.

OPU

PPU

QPU - Quantum Processing Unit

​ A quantum processing unit (QPU), also referred to as a quantum chip, is a physical (fabricated) chip that contains a number of interconnected qubits. It is the foundational component of a full quantum computer, which includes the housing environment for the QPU, the control electronics, and many other components.

RPU

SPU

TPU - Tensor Processing Unit

​ Tensor Processing Units are Google's ASIC for machine learning. TPUs are specifically used for deep learning to solve complex matrix and vector operations. TPUs are streamlined to solve matrix and vector operations at ultra-high speeds but must be paired with a CPU to give and execute instructions. TPUs may only be used with Google's TensorFlow or TensorFlow Lite platform, whether through cloud computing or its lite version on local hardware.

UPU

VPU - Vector Processing Unit

​ Vector processing units (VPUs) perform the actual work of computing a SIMD vector operation in parallel.

​ Many of today's server-class Intel processors, including those on Stampede2, are equipped with two VPUs per core.
