An idea of the so-called quasi-maximum accuracy computations for improvement of precision of the floating-point digital signal processing with graphic processing units (GPUs) is presented in this paper. In the presented approach, the increase of the precision of computations does not need any increase of the length of the data words. Special attention has been paid to efficiency and precision of computations...
W artykule zaprezentowano ideę wykorzystania modelu dwóch akumulatorów w celu poprawy precyzji obliczeń dokonywanych na procesorach graficznych (GPU). Zastosowanie dwóch akumulatorów zmiennoprzecinkowych pozwala na zwiększenie precyzji obliczeń bez wydłużania słów danych. Jest to szczególnie istotnie w przypadkach ograniczeń sprzętowych co do precyzji obliczeń, jakie mają miejsce w procesorach graficznych...
