Formal specification of an FPGA based educational microprocessor

The goal of the project Edulent has been to produce specification and design of an educational microcomputer that is simple enough to be implemented on a medium complexity FPGA. In this paper we present formal specification of the Edulent by using Register Transfer Notation (RTN) language. The RTN specification is refined into concrete specification that is the foundation of the Edulent design. We also present some design and implementation details and the features of the final product.
