multicoremultiprocessor
Multicore multiprocessor is a processor that contains two or more processing cores on a single integrated circuit. Each core can execute instructions independently, enabling parallelism for multi-threaded workloads. In most designs, cores share some resources such as caches and memory controllers, while maintaining separate execution pipelines and registers.
Key design features include a shared L2 and/or L3 cache, an on-die interconnect, and a memory subsystem
Performance gains come from increased instruction throughput, but depend on software parallelism and data locality. Amdahl's
Multicore multiprocessors are distinct from multi-processor systems that use multiple CPUs on a motherboard. They can
Common examples include Intel Core, AMD Ryzen, and ARM-based cores used in laptops, desktops, and mobile devices.
