Apstrakt
U ovom radu je modelovan podsistem skrivene (keš, eng. cache) memorije za RISC-V procesor. Model je pisan u VHDL jeziku te je ciljan za soft-core primenu na FPGA uređajima. Model se sastoji iz dva nivoa keš hijerarhije: prvi nivo je direktno preslikan i razdeljen, dok je drugi N-smerno set asocijativan i unificiran. Model je parametrizovan, te korisnik ima mogućnost da bira kapacitet memorija kao i asocijativnost. Sistem je zajedno sa jednostavnim RISC-V procesorom prvo simuliran pomoću Vivado alata a zatim upakovan u IP jezgro, implementiran i testiran na Zybo razvojnoj ploči.
