Due to the ever increasing number of microprocessors which can be integrated in very large systems on chip the need for robust, easily modifiable microprocessors has emerged. Within this paper a light-weight cycle compatible implementation of the MicroBlaze architecture called MB-LITE is presented in an attempt to fill the gap in quality between commercial and open source processors. Experimental results showed that MBLITE obtains very high performance compared with other open source processors while using very few hardware resources. The microprocessor can be easily extended with existing IP thanks to an easily configurable data memory bus and a wishbone bus adapter.
