A single-core processor is a microprocessor with a single CPU on its die. [1] It performs the fetch-decode-execute cycle one at a time, as it only runs on one thread . A computer using a single core CPU is generally slower than a multi-core system.

M·CORE processors, like 68000 family processors, have a user mode and a supervisor mode, and in user mode both see a 32 bit PC and 16 registers, each 32 bits. The M·CORE instruction set is very different from the 68k instruction set—in particular, M·CORE is a pure load-store machine and all M·CORE instructions are 16 bit, while 68k ...
The ARM Cortex-A9 MPCore is a 32-bit multi-core processor that provides up to 4 cache-coherent cores, each implementing the ARM v7 architecture instruction set. [1] It was introduced in 2007. [ 2 ]
POWER8, 64-bit, hex or twelve core, 8 way SMT/core, 5.0 GHz, follows the Power ISA 2.07. Introduced in 2014. POWER9, 64-bit, PowerNV 24 cores of 4 way SMT/core, PowerVM 12 cores of 8 way SMT/core, follows the Power ISA 3.0. Introduced in 2016. Power10, 64-bit, 15 SMT8 or 30 SMT4 cores, will follow the Power ISA 3.1. Introduced in 2021.
Bulldozer is the first major redesign of AMD’s processor architecture since 2003, when the firm launched its K8 processors, and also features two 128-bit FMA-capable FPUs which can be combined into one 256-bit FPU. This design is accompanied by two integer clusters, each with 4 pipelines (the fetch/decode stage is shared).
The 32-bit microprocessor dominated the consumer market in the 1990s. Processor clock speeds increased by more than tenfold between 1990 and 1999, and 64-bit processors began to emerge later in the decade. In the 1990s, microprocessors no longer used the same clock speed for the processor and the RAM.
