What is numeric processing unit?
The Numeric Processing Unit is a specialized version of a CPU, it can ONLY preform math operations, but does them at a much faster rate than the CPU. Because it is directly controlled by the CPU the NPU does not have ANY address selection ability. Therefore , it has NO connection to the address bus. (Note hte direct connection to the CPU , in modern systems the NPU is physically part of the CPU).
What is a Arithmetic logical unit?
The Arithmetic Logic Unit (ALU) is the heart of a CPU. This is what allows the computer to add, subtract, and to perform basic logical operations.
What is a basic set of commands permanently built into the CPU chip to perform fundamental operations such as comparing or adding two numbers?
CPU's vary For example, a 6502 processor has instructions liks ADC (add with carry), CMP (compare), CPX (Compare A with X) and CPY (Compare A with Y)
Is CPU speed a ratio or interval?
ratio
What performs the arithmetic computation and logic operations in the CPU?
ALU
A CPU executes only?
A CPU does math and accesses memory.
What are the speed of CPU?
The CPU speed, and processor speed is the amount of cycles that a CPU can perform per second.CPU speed is not a good indicator of CPU performance.
Does computer perform multiplications and subtraction.?
Yes. In windows its often located in Start > Programs > Accessories > Calculator. They perform this using a math processor built into the CPU (Central Processing Unit). Older computers had a separate math processor called a Math-CoProcessor
What is the first CPU to include an internal math coprocessor?
486SX
What is a command to the CPU to perform one processing function on one or two data inputs?
An instruction is a command to the CPU to perform one processing function on one or two data inputs.
What is it called when a device requests the CPU to perform a task?
interrupt controller
What is an instruction?
The set of instructions, on the CPU chip, that the computer can perform directly.
What Does hammer use my GPU or CPU?
hammer uses Both- GPU to render the scene in, and your CPU to compile the maps and perform calculations.
What difference between cluster system and multiprocessor system?
in cluster system, different CPU's work together to perform a specific task while in multiprocessor system,different CPU's work to perform their own tasks.
Which part of CPU perform logical function?
ALU-Arithmetic and logic unit.
Which processor first integrated the math coprocessor in the CPU chip?
your mom!intel1883
When a device needs the CPU to perform a task what does it need to do?
The device needs to signal the CPU to get its attention. It typically does this through an interrupt request line (IRQ).
