CPU

(Central Processing Unit) The computing part of the computer. Also called the "processor," it is made up of the control unit and ALU. Today, the CPUs of almost all computers are contained on a single microprocessor chip. In fact, multiple processing units on one chip are commonplace (see multicore). See microprocessor, control unit and ALU.

Computer Vs. Computer System
Technically, the CPU, clock and main memory make up a computer. A complete computer system requires the addition of peripheral control units, input, output and storage devices and an operating system. In practice, the terms "computer" and "computer system" are synonymous.

From the Old Mainframer's Viewpoint
Years ago, computer professionals involved with mainframes referred to the whole computer as the CPU, in which case, CPU referred to the processor, memory (RAM) and input/output channels.


Central Processing Units
Years ago, a CPU was the processor, memory and everything inside the cabinet. Today, a CPU is generally nothing more than a microprocessor.

One new tactic being taken is to implement multiple servers (usually between 3 to 10) in order to improve performance and scalability, with the goal of introducing parallelism into the NAS file-serving process by having lots of CPUs working together on the problem.
In the very near future, many of today's production-level servers will not only be virtualized but will be configured for and capable of performing internal performance audits or "automated health checks" (from I/O processing needs at the CPU and memory level to page and buffer credit settings at the kernel level).
D-Tek paid careful attention to the manufacturability of the FuZion CPU block, exerting exceptional quality control - including leak-testing each part and ensuring consistent manufacturing from one block to the next.
Hardware-based modems consume the least amount of CPU resources during operation.

In this model, the CPU hardware is responsible for fetching instructions from memory, decoding them into micro-operations, and then reordering them so they can be executed in parallel by the processor.
Combining CPU Tech's experience and IP with IBM's PowerPC technology will provide customers a programmable, high performance, SoC solution capable of helping customers modernize legacy systems into leading edge systems," said Ron Martino, Director of PowerPC Standard Products, IBM Technology Collaboration Solutions.
It is no longer possible to use a CPU for this task and designing custom XOR generating hardware becomes increasingly more complex and difficult.
CPU TECH began providing Bradley Position Interface Box two years ago with a modern System on Chip (SoC)-based PIB that is smaller, lighter, more reliable and lower cost than earlier systems.
The HyperTransport Consortium has also released the HyperTransport HTX(TM) connector specification which enables system designers to link high-performance peripheral subsystems directly to the system's CPU or CPUs via low-latency HyperTransport links.
ARC's patented configurable CPU technology assists customers in the development of next generation digital media, consumer and communications devices, resulting in lower cost, higher performance SoC products.
According to the latest study released by Semico, the use of Configurable 32-bit CPU cores is going to be the next major driver in several of the sub-families in the ASIC market, such as the System-on-a-Chip (SoC), the Structured ASIC, the Application Specific Standard Product (ASSPs) and Field Programmable Gate Arrays (FPGAs).
