In computer engineering, an execution unit (E-unit or EU) is a part of a processing unit that performs the operations and calculations forwarded from the instruction unit. [1] It may have its own internal control sequence unit (not to be confused with a CPU's main control unit), some registers, [2] and other internal units such as an arithmetic ...
A modern CPU also tends to include an interrupt controller. It handles interrupt signals from the system bus. The control unit is the part of the computer that responds to the interrupts. There is often a cache controller to cache memory. The cache controller and the associated cache memory is often the largest physical part of a modern, higher ...
