    ABSTRACT

    This paper deals with a CMOS standard-cell Application Specific Integrated Circuits (ASIC) implementation of a SoC (System on Chip) based on the OpenRISC processor for Voice over IP (VoIP) application. A hybrid approach was adopted where the design is first prototyped on an FPGA (Fieldprogrammable gate array) platform for functional validation and then implemented as an ASIC using the TSMC 0.18 μm process technology. The architecture of the design is mainly based on the reuse of IPs cores described at the RTL level from Opencores. This RTL code is technology-independent, thus the design can be ported easily from FPGA to ASIC. Results show that the SoC occupied the area of 6.74mm2 and the ASIC power consumption of the design is 18 times less than FPGA power consumption.
