Abstract: The parameterized design about the C8051 micro controller IP soft core is studied. Firstly, he design of the instruction system is introduced. Secondly, from the reconfigurable capacitance of emory, parallel input/output port, UART and timer/counter which can be accepted or rejected, and he reconfigurable multiplier, the detailed method for the C8051 micro controller IP soft core about arameterized design is described. Finally, the verification of simulation, the result of synthesis and he delay analysis using different configurable parameters are introduced. The parameterized design ethod enhances the reconfigurable and reusable of IP soft core in the field of System on Chip design.
