A microprogrammable-processor teaching tool and its FPGA implementation

摘要

In this paper a microprogrammable-processor teaching tool and its FPGA implementation are presented. The processor is based on a classical Am2900 architecture and is implemented in the popular Xilinx Foundation~(TM) environment. The tool helps electrical and computer engineering students to become familiar with microprogramming through development of their own instruction sets and experiments with signal flow within a processor. In addition to simulation, the complete configuration can be run on a Xilinx 4010XL FPGA. In the paper a short description of the tool is provided.
