Embedded System Design Using FPGAs Module F 1 -1

What is an Embedded System It is not a PC! Most computers in the world do not have a keyboard and screen. The vast majority of computers in the world are small chips that are hidden inside all kinds of products.

Embedded System Design Microprocessors Programming languages • Assembly language • C, C++, JAVA, ADA • Forth, WHYP ASICs and FPGAs Schematic capture Hardware Description Languages (HDLs) • VHDL • Verilog

Embedded System Design FPGA MPU FPGA ASIC

Embedded System Design MPU FPGA

Microprocessor Unit (MPU) Simple – not much area of FPGA Probably not a 32 -bit RISC Maybe an 8 -bit or 16 -bit stack-based design Fast Single clock cycle instructions where possible Easy to program Probably not C or C++ Maybe FORTH or WHYP

Embedded System Design FPGA MPU FPGA ASIC Goal: Design entire embedded system as a single FPGA. Use VHDL to design all hardware including the MPU. Write the MPU software in WHYP and compile to VHDL.

Potential Advantages Minimize overall system cost Minimize development time Minimize per unit cost Implement only the hardware and software needed for a particular design
