| Historically designers created computing systems by combining Integrated Circuits (ICs) on Printed Circuit Boards (PCBs), whereas now they are able to form complete Systems-on-Chip (SoCs). For the purpose of this study, SoCs are defined as a collection of functional units on one chip that interact to perform a desired operation. These modules are typically of a coarse granularity to promote reuse of previously designed Intellectual Property (IP). The decreasing size of process technologies enables designers to implement increasingly complex SoCs using both Application Specific Integrated Circuits (ASICs) and Field Programmable Gate Arrays (FPGAs). The impact of increasing design complexity is increased design time and costs for electronics. Therefore, this research investigates methods to facilitate the design of SoCs through both architecture and CAD tools.;This thesis has two main contributions. The first is an architectural framework for SoCs, wherein they are modelled as Systems Integrating Modules with Predefined Physical Links (SIMPPL). The strength of the model is the Computing Element (CE) abstraction that separates the module's datapath from system-level control and communications to facilitate design reuse. Although SIMPPL can be used to build SoCs for ASICs or FPGAs, using an FPGA provides designers with a reprogrammable implementation platform. Thus, our second contribution is to develop a design infrastructure that leverages the advantages of reconfigurability. |
