A Prototyping IP Hardware for SOPC with Single Instruction Driving

Embedded systems are most popular applications in computer engineering. SOPC, system on a programmable chip, is a hot point of research and development for embedded systems. A SOPC is to integrates microprocessor and IP cores into one chip. The IP cores can be built for various functions. In order to take better efficiency and performance, an operation had better to be driven by some single instruction in a SOPC. This paper is focused on some customized hardware design technology for SOPC IP cores based on FPGA. An approach of IP design for a reconfigurable SOPC is discussed. As an example, the design is described for an external RAM controller with single instruction driving. Since the SOPC is reconfigurable, a read/write instruction for external RAM is easy to add into instruction rule set of the SOPC microprocessor. Results of simulation and test show that the design is successful
