founded 2004 1 headquarters israel products multi core website plurality.com 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 . 2 contents 1 hypercore 2 patents 2.1 synchronizer scheduler 3 see also 4 references 5 external links hypercore edit plurality develops the hypercore cpu technology which is a mimd 32 bit risc based multi processor on a single chip 3 and contains from 16 to 256 cores . 4 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 5 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 . patents edit synchronizer scheduler edit dr. nimrod bayer and dr. ran ginosar two of plurality s founders received united states patent 5202987 a high flow rate synchronizer scheduler for multiprocessors for the company s core technology on april 13 1993 . the patent has been cited by more than 30 subsequent patents . the patent abstract is as follows a high flow rate synchronizer scheduler apparatus for a multiprocessor system during program run time comprises a connection matrix for monitoring and detecting computational tasks which are allowed for execution containing a task map and a network of nodes for distributing to the processors information or computational tasks detected to be enabled by the connection matrix . the network of nodes possesses the capability of decomposing information on a pack of allocated computational tasks into messages of finer sub packs to be sent towards the processors as well as the capability of unifying packs of information on termination of computational tasks into a more comprehensive pack . a method of performing the synchronization scheduling in the multiprocessor system of this apparatus is also described . see also edit parallel computing parallel programming model speedup task parallelism references edit plurality s profile multicore association member list massively parallel processors for dsp breaking moore s law hebrew plurality s hypercore joins the multi core fray external links edit wikimedia commons has media related to plurality . plurality s website plurality s hal kicking ass on core street retrieved from https en.wikipedia.org w index.php title plurality company & oldid 647093649 categories companies established in 2004fabless semiconductor companieshidden categories commons category without a link on wikidata navigation menu personal tools not logged intalkcontributionscreate accountlog in namespaces article talk variants views read edit view history more search navigation main pagecontentsfeatured contentcurrent eventsrandom articledonate to wikipediawikipedia store interaction helpabout wikipediacommunity portalrecent changescontact page tools what links hererelated changesupload filespecial pagespermanent linkpage informationwikidata itemcite this page print export create a bookdownload as pdfprintable version languages add links this page was last modified on 14 february 2015 at 12 43 . text is available under the creative commons attribution sharealike license ; additional terms may apply . by using this site you agree to the terms of use and privacy policy . wikipedia is a registered trademark of the wikimedia foundation inc. a non profit organization . privacy policy about wikipedia disclaimers contact wikipedia developers cookie statement mobile view
