One example of such “shmooing” is the procedure for optimising the two operating variables of the Read Only Storage (ROS) in the IBM S/360 Model 65 Central Processing Unit (CPU). While the CPU is running a diagnostic test program the ROS bias voltage and time delay are varied and the points where the ROS generates errors are manually ...
A CPU cache [71] is a hardware cache used by the central processing unit (CPU) of a computer to reduce the average cost (time or energy) to access data from the main memory. A cache is a smaller, faster memory, closer to a processor core, which stores copies of the data from frequently used main memory locations.
CoreMark is a benchmark that measures the performance of central processing units (CPU) used in embedded systems.It was developed in 2009 [1] by Shay Gal-On at EEMBC and is intended to become an industry standard, replacing the Dhrystone benchmark. [2]
Minimal instruction set computer (MISC) is a central processing unit (CPU) architecture, usually in the form of a microprocessor, with a very small number of basic operations and corresponding opcodes, together forming an instruction set. Such sets are commonly stack-based rather than register-based to reduce the size of operand specifiers.
In computer science, an instruction set architecture (ISA) is an abstract model that generally defines how software controls the CPU in a computer or a family of computers. [1] A device or program that executes instructions described by that ISA, such as a central processing unit (CPU), is called an implementation of that ISA.
The Synergistic Processing Element or Unit (SPE or SPU) is a component in the Cell microprocessor. Processors based on different circuit technology have been developed. One example is quantum processors , which use quantum physics to enable algorithms that are impossible on classical computers (those using traditional circuitry).
The control unit (CU) is a component of a computer's central processing unit (CPU) that directs the operation of the processor. A CU typically uses a binary decoder to convert coded instructions into timing and control signals that direct the operation of the other units (memory, arithmetic logic unit and input and output devices, etc.).
In computer architecture, multithreading is the ability of a central processing unit (CPU) (or a single core in a multi-core processor) to provide multiple threads of execution. Overview [ edit ]
