Single-core

A single-core, processor is a microprocessor with a single core on a chip, running a single thread computing thread at any one time. The system of single core consume a lot of time since running a single thread, this become more advanced after the emergence of multi-core processors which have several independent processors on a single chip hence performing a lot of function at a time. Hence serves time,example Intel released a Core 2 Solo and Core 2 duo

Increasing parallel trend

• Single-core – one processor on a die. Since about 2012, even most smartphone CPUs marketed are no longer single-core; Microcontrollers are still single-core, while there are exceptions.
• Multi-core – a 'few' processors on a die, e.g. 2, 4, 8.
• Many-core – a 'large number' of processors on a die, e.g. 10s, 100s, 1000s. Some specialist ASICs/Accelerators and GPUs fall into this category.
