Study on micro controller design and verification methodology

In this paper, we introduce the design and verification methodology of 16 bits microcontroller, which is compatible with 8 bits microcontroller, 8051, widely used in the industrial fields these days. To confirm our design, we verified our design for all instruction sets and various combinational sets of them. Also we propose new idea for verification of various instruction sets. We verified our design through some application programs such as IMA-ADPCM. Finally, we verified our design for all instruction sets and application programs using an application board configured two Xilinx FPGAs (XCV1000-560C). After verification for various cases, we concluded that we can substitute our design for 8051 and also our design can be operated more powerfully than 8051.
