Abstract [en]

In recent years, developers have wanted to design more complex and advanced embedded processors. The feasibility of developed processors must be verified before the actual application. However, the process of verification always needs high costs and time. Quick Emulator (QEMU), a virtual platform emulator, can help in this situation. It can emulate different processors and hardware environments and build a unique platform according to the designers wishes. Many people have used QEMU to emulate advanced Reduced Instruction Set Computing (RISC) processors (like ARM) or the X86 architectures. Still, there is little research on RISC-V processors. Therefore, studying the QEMU to emulate the RISC-V processor is important. This thesis aims to evaluate the performance of the RISC-V processor using QEMU. Ten different benchmarks are designed, and their results are compared to reflect the performance of the RISC-V as well as the simulator. These results provide a reference when these benchmarks are run on the RISC-V processor that is on the actual hardware development board.

Abstract [sv]

De senaste åren har utvecklarna alltid velat utveckla mer komplexa och avancerade funktioner på inbyggda utvecklingskort. Men de nya funktionerna måste verifieras innan man gör kretskortet. Å andra sidan så kostar verifieringsprocessen mycket tid och pengar. Quick Emulator (QEMU), en virtuell plattformsemulator, kan hjälpa till för att lösa detta problem. Den kan emulera olika processorer och hårdvarumiljöer och bygga en unik plattform allt enligt designernas önskemål. Många människor har använt QEMU för att emulera avancerade Reduced Instruction Set Computing (RISC)-processorer (som ARM), eller X86-arkitekturerna, men det finns mycket lite forskning om RISC-V processorer. Därför är det viktigt att studera QEMU för att emulera RISC-V-processorn. Denna avhandling syftar till att utvärdera prestandan för RISC-V processorer genom att använder QEMU. Tio olika benchmarks konstrueras för att användas för att spegla prestandan hos processorn såväl som simulatorn. Dessa resultat kan sedan användas som referens när benchmarken körs på de RISC-V-processorer som finns på det aktuella hårdvaruutvecklingskortet.
