Abstract :
This paper presents a micro-architectural feature in a processor´s datapath to support the C language´s runtime environment. A hardware accelerator for C function calls was embedded in a processor core and its impact on area and performance was evaluated. Results show that the accelerator offers a performance improvement in several different processor configurations. The performance gain depends on the utilized processor configuration, especially on memory access contention.
