uRT51: An embedded real-time processor implemented on fpga devices

In this paper we describe and evalu- ate the main features of the uRT51 processor. The uRT51 processor was designed for embedded real- time control applications. It is a processor architec- ture that incorporates the specific functions of a real-time system in hardware. It was described using synthesizable VHDL and it was implemented on FPGA devices. We describe how the uRT51 proces- sor supports time, events, task and priorities. The performance of the uRT51 processor is evaluated using a control application as a case study. The ex- periments show that the uRT51 processor schedul- ing features outperform the ones obtained using a traditional RTOS-based real-time system.
