Study Notes
Multicore Systems
- Contain two or more cores that share some resources.
- Can execute instructions from multiple threads concurrently.
Simultaneous Multithreading
- One core (CPU) executes instructions from multiple threads.
- Designed to better exploit functional units in hardware.
Symmetric Multiprocessor (SMP)
- Consists of two or more full processors.
- Can be combined with multicore and/or simultaneous multithreading.
- Often used to speed up processing of complex applications.
- Can be combined with accelerators to further enhance performance.
