Advanced Topic 37 of 51 Computer Architecture & Logic
Multicore Processors
Chips with several independent processing cores.
How it works
Several cores on one chip run threads in parallel, sharing some caches and memory. Single-thread speed gains slowed, so performance now comes from parallelism.
Where it is used
Servers, phones, laptops.
Common pitfall
Software must be parallelized; Amdahl's law limits speedup.
Where it fits in the course
Multicore Processors is topic 37 of 51 in Computer Architecture & Logic, rated Advanced. It follows Speculative Execution. The next topic is Cache Coherence.
