This text is intended as a supplementary text and laboratory manual for undergraduate students in a contemporary course in digital logic and embedded systems. Professionals who have not had an exposure to the coarse grained FPGA, the Verilog HDL, an EDA software tool or the new paradigm of the controller and datapath and the FSM will find that this text facilitates an expansive experience with the tenets of digital signal processing, communications and control in embedded design. The References sections at the end of each Chapter contain a list of suitable undergraduate and graduate texts and reference books.
Trends in Embedded Design Using Programmable Gate Arrays describes the analysis and design of modern embedded processing systems using the field programmable gate array (FPGA). The FPGA has traditionally provided support for embedded design by implementing customized peripherals, controller and datapath constructs and finite state machines (FSM). Although microprocessor-based computer systems have usually been used for the design of larger scale embedded systems, the paradigm of the FPGA now challenges that notion of such a fixed architecture especially with the constraints of real-time.
This new paradigm in embedded design utilizes the Verilog hardware description language (HDL) behavioral synthesis of controller and datapath constructs and the FSM for digital signal processing , communications and control with the FPGA, external interface hard core peripherals, custom internal soft core peripherals and the soft core processor. The transition to embedded design with the parallel processing capabilities and coarse grained architecture of the modern FPGA is described by in-part by the translation of C/C++ program segments for real-time processing to a controller and datapath construct or an FSM. However, the availability of the Xilinx 8-bit PicoBlazeTM and 32-bit MicroBlazeTM soft core processors and the emergence of the ARM® hard core processor and AMBA bus for the Xilinx Zynq™ Extensible Processing Platform (EPP) now also challenges the conventional microprocessor with its fixed architecture for embedded design.
Trends in Embedded Design Using Programmable Gate Arrays features the Xilinx Spartan®-6 FPGA on the Digilent NexysTM 3 Board and the AtlysTM Board evaluation hardware, the Xilinx Integrated Synthesis Environment (ISE®) electronic design automation software tool in the Verilog HDL, Xilinx CORE Generator for LogiCORE™ blocks and an introduction to the Xilinx Zynq EPP. The complete Xilinx ISE projects and Verilog HDL modules described in the Chapters are available for download.
The prior text (2008) Embedded Design Using Programmable Gate Arrays features the Xilinx Spartan-3E™ FPGA and the Digilent Basys Board and the Spartan-3E Starter Board and is described here.
