Mazkur maqolada OpenMP texnologiyasi asosida ko‘p yadroli protsessorlarda signalga raqamli ishlov berish jarayonlarini parallellashtirish masalalari yoritilgan. Tadqiqotda ketma-ket va parallel hisoblash usullari solishtirilib, ularning samaradorlik ko‘rsatkichlari ishlov berish vaqti, speedup, samaradorlik foizi tahlil qilingan. OpenMP texnologiyasining “shared memory” arxitekturasi asosida parallel sikllarni tashkil etish imkoniyatlari ko‘rsatib o‘tildi. Natijalar shuni ko‘rsatadiki, OpenMP yordamida signalga ishlov berish jarayoni 5 martagacha tezlashadi, hisoblash samaradorligi esa 60–95% oralig‘ida bo‘ladi. Bu esa OpenMP texnologiyasi ilmiy va muhandislik hisoblashlarda, xususan tibbiy tasvirlar va raqamli signallarga ishlov berishda samarali yechim ekanini tasdiqlaydi.
