floating point coprocessor

floating point coprocessor
matematinis koprocesorius statusas T sritis informatika apibrėžtis ↑Procesorius, atliekantis aritmetines operacijas su ↑slankiojo kablelio skaičiais. Šios operacijos yra gana sudėtingos. Matematinis koprocesorius būna specialiai joms pritaikytas ir labai paspartina matematinius skaičiavimus, todėl populiarus asmeniniuose kompiuteriuose. Tam, kad matematinis koprocesorius veiktų, reikia numatyti jo panaudojimą programinėje įrangoje. atitikmenys: angl. floating point coprocessor; math coprocessor; numeric coprocessor ryšiai: dar žiūrėkprocesorius dar žiūrėkslankiojo kablelio skaičius
