Microprocessor Computer processor contained on an integrated-circuit chip

A microprocessor is a computer processor where the data processing logic and control is included on a single integrated circuit, or a small number of integrated circuits. The microprocessor is a multipurpose, clock-driven, register-based, digital integrated circuit that accepts binary data as input, processes it according to instructions stored in its memory, and provides results as output. Microprocessors contain both combinational logic and sequential digital logic. Microprocessors operate on numbers and symbols represented in the binary number system.

PowerPC RISC instruction set architecture by AIM alliance

PowerPC is a reduced instruction set computer (RISC) instruction set architecture (ISA) created by the 1991 Apple–IBM–Motorola alliance, known as AIM. PowerPC, as an evolving instruction set, has since 2006 been named Power ISA, while the old name lives on as a trademark for some implementations of Power Architecture–based processors.

Reduced instruction set computer Processor executing one instruction in minimal clock cycles

A reduced instruction set computer, or RISC, is a computer with a small, highly optimized set of instructions, rather than the more specialized set often found in other types of architecture, such as in a complex instruction set computer (CISC). The main distinguishing feature of RISC architecture is that the instruction set is optimized with a large number of registers and a highly regular instruction pipeline, allowing a low number of clock cycles per instruction (CPI). Core features of a RISC philosophy are a load/store architecture, in which memory is accessed through specific instructions rather than as a part of most instructions in the set, and requiring only single-cycle instructions.

Nvidia American technology company

Nvidia Corporation is an American multinational technology company incorporated in Delaware and based in Santa Clara, California. It designs graphics processing units (GPUs) for the gaming and professional markets, as well as system on a chip units (SoCs) for the mobile computing and automotive market. Its primary GPU line, labeled "GeForce", is in direct competition with the GPUs of the "Radeon" brand by Advanced Micro Devices (AMD). Nvidia expanded its presence in the gaming industry with its handheld game consoles Shield Portable, Shield Tablet, and Shield Android TV and its cloud gaming service GeForce Now.

ARM is a family of reduced instruction set computing (RISC) architectures for computer processors, configured for various environments. Arm Ltd. develops the architecture and licenses it to other companies, who design their own products that implement one of those architectures‍—‌including systems-on-chips (SoC) and systems-on-modules (SoM) that incorporate different components such as memory, interfaces, and radios. It also designs cores that implement this instruction set and licenses these designs to a number of companies that incorporate those core designs into their own products.

The AIM alliance was formed on October 2, 1991, between Apple, IBM, and Motorola to create a new, grandly unified, computing standard based on the POWER instruction set architecture. It was further intended to cope with Microsoft's monopoly and the Wintel duopoly. The alliance yielded the launch of Taligent, Kaleida Labs, the highly successful PowerPC CPU family, the Common Hardware Reference Platform (CHRP) hardware platform standard, and Apple's highly successful Power Macintosh computer line.

OpenRISC is a project to develop a series of open-source hardware based central processing units (CPUs) on established reduced instruction set computer (RISC) principles. It includes an instruction set architecture (ISA) using an open-source license. It is the original flagship project of the OpenCores community.

In electronic design, a semiconductor intellectual property core, IP core, or IP block is a reusable unit of logic, cell, or integrated circuit layout design that is the intellectual property of one party. IP cores can be licensed to another party or owned and used by a single party. The term comes from the licensing of the patent or source code copyright that exists in the design. Designers of application-specific integrated circuits (ASIC) and systems of field-programmable gate array (FPGA) logic can use IP cores as building blocks.

Transistor count Number of transistors in a device

The transistor count is the number of transistors in an electronic device. It typically refers to the number of MOSFETs on an integrated circuit (IC) chip, as all modern ICs use MOSFETs. It is the most common measure of IC complexity. The rate at which MOS transistor counts have increased generally follows Moore's law, which observed that the transistor count doubles approximately every two years.

Tegra System on a chip by Nvidia

Tegra is a system on a chip (SoC) series developed by Nvidia for mobile devices such as smartphones, personal digital assistants, and mobile Internet devices. The Tegra integrates an ARM architecture central processing unit (CPU), graphics processing unit (GPU), northbridge, southbridge, and memory controller onto one package. Early Tegra SoCs are designed as efficient multimedia processors, while more recent models emphasize performance for gaming and machine learning applications, without sacrificing power efficiency.
