SCARTS Processor for Embedded Systems with Real-time Requirements

The SCARTS processor is small and flexible processor, which has been specifically designed for embedded systems with real-time requirements. The deterministic architecture (all instructions execute in a single cycle) and the support of conditional instructions significantly simplify the task of WCET analysis. For SW development there is a toolchain based on the GNU Binutils/GCC/GDB. Furthermore there is a port of the Red Hat Newlib, a C standard library for embedded systems.
