*a central processing unit (CPU) is the ‘electronic circuitry’ within a computer that carries out the instructions of a ‘computer program’ by performing the (‘basic arithmetic’ / ‘logic’ / ‘controlling’ / ‘input – output (I/O) operations) specified by the ‘instructions’*
.
(input/output (I/O) operations specified by the ‘instructions’)
.
(the computer industry has used the term “central processing unit” at least since the ‘early 1960s’)
(traditionally, the term “CPU” refers to a ‘processor’, more specifically to its ‘processing unit’ + ‘control unit’ (CU), distinguishing these ‘core elements’ of a computer from external components such as ‘main memory’ + ‘I/O circuitry’)
(the (‘form’ / ‘design’ / ‘implementation’) of CPUs have changed over the course of their history, but their fundamental operation remains almost unchanged)
.
(principal components of a CPU include…)
(the ‘arithmetic logic unit’ (ALU) that performs ‘arithmetic’ + ‘logic’ operations)
.
*’processor registers’ that supply ‘operands’ to the ‘ALU’ + store the results of ‘ALU operations’ and a ‘control unit’ that orchestrates the ‘fetching’ (from ‘memory’)*
.
*the execution of instructions by directing the ‘coordinated operations’ of the (‘ALU’ / ‘registers’ / ‘other components’)*
.
(most modern CPUs are ‘micro-processors’, meaning they are contained on a ‘single integrated circuit’ (IC) chip)
.
(an ‘IC’ that contains a ‘CPU’ may also contain…)
‘memory’
‘peripheral interfaces’
*other components of a computer*
.
(such integrated devices are variously called ‘micro-controllers’ or systems on a chip (SoC))
(some computers employ a ‘multi-core processor’, which is a ‘single chip’ containing 2 or more CPUs called “cores”)
(in that context, one can speak of such single chips as “sockets”)
(‘array processors’ (or ‘vector processors’) have multiple processors that operate ‘in parallel’, with no unit considered ‘central’)
.
(there also exists the concept of ‘virtual CPUs’ which are an ‘abstraction’ of ‘dynamical aggregated computational resources’)
