In today’s globally interconnected world, we notice a proliferation of a vast array of electronic devices and systems in our daily life, from industrial automation, military, aerospace, aviation, medicine, consumer electronics to multimedia and entertainment products. The common thread that binds all these devices is that they involve some kind of a human-computer interface that helps the end-user of these devices interact and control the computational system within each device. Such a human –computer interface typically involves some kind of a Digital Signal Processing (DSP) module whose specific task is to accept as input a real-world analog signal, convert it into a digital signal and process the digital signal by means of extracting useful information through transformation, analysis and synthesis to eventually deliver a result that can help in making a decision. Hence DSP serves as the “interface” between the analog domain of real-life signals and the computational world of digital signals. The most widely used hardware platform for DSP system implementation is the Programmable Digital Signal Processor (PDSP). The PDSPs are general purpose microprocessors designed for embedded DSP applications. They contain special architecture and instructions that support execution of computation - intensive DSP algorithms more efficiently. However, rapid advancements in CMOS technology have widened the options available to a hardware engineer for DSP system implementation. The advent of Field Programmable Gate Arrays (FPGAs) with in-built hardware blocks like DSP multiplier cores, hard and soft IP cores and high-level synthesis tools has given the PDSP a strong competitor. A multitude of factors such as development effort, design time, performance in terms of power consumption and speed, time-to-market, prototyping capabilities, design methodologies and architectural flexibility should be considered for DSP system implementation. This thesis makes a comparative study of the two hardware platforms – PDSP and FPGA – in terms of design methodologies, architectures, design time and effort and impact of high-level synthesis tools. The objective is to help a DSP hardware engineer make an informed decision on the pros and cons of selecting a particular hardware platform.
