Plurality (company)
Plurality Ltd. is an Israeli semiconductor company, the developer of the HyperCore technology and the HAL (HyperCore Architecture Line) multi-core processor. The company is a member of the Multicore Association.〔(Multicore Association member list )〕
== HyperCore ==
Plurality develops the HyperCore CPU technology, which is a MIMD 32-bit RISC based multi-processor on a single chip,〔(Massively parallel processors for DSP )〕 and contains from 16 to 256 cores.〔(Breaking Moore's law (Hebrew) )〕 HyperCore technology supports executing both fine-grained and coarse-grain parallelism due to its special hardware Synchronizer/Scheduler, shared memory and task based programming model.
The HyperCore technology's synchronizer/scheduler (patented,〔(Plurality's Hypercore Joins the Multi-Core Fray )
〕 see below also) eliminates the need of repeatedly executing a special kernel program controlling and deciding which task (or thread) to currently assign and execute on a given processor. The ability to synchronize tasks in hardware allows the processor to support fine-grained programs and to achieve almost a linear speedup. Fine grained programs can only be executed when tasks' duration is significantly shorter than the overhead time introduced by the scheduler. The HyperCore's shared memory (patent pending) avoid the coherency problem and keep a single memory space for all cores in the system thus simplifying the programming model significantly.
