The gates have fixed relationships designed to accomplish fixed functions. These gates write data onto buses, into latches and registers, out ports, and across channels. Nothing new here.Д¬ompiling The process of compiling a program for the microprocessor combines the edited files and builds a logically correct sequence of bits that are used to control the sequencing of logical gates. Architectural issues could fill a book therefore we'll focus on development issues.Д«ecause you understand editing, compiling, assembling, linking, and loading in microprocessor programming, you can relate this to editing, compiling, synthesizing, placing, routing, and loading in FPGA programming.Д®diting Not only is Verilog syntax C-like, but, since it's 100% ASCII, you can use any editor to prepare fpga.v files. Thus the ability to express yourself in C is a good start in learning Verilog. I describe my first FPGA architectural design in a pseudo-C language then translate it to Verilog for an FPGA. Although people will argue design philosophies, it's not unusual to perform a 'first cut' at programming in a pseudo-language that can be translated into and refined as a specific language, say assembly, C++, or JAVA. TTF)ДЄrchitectural design The architectural-design phase is surprisingly similar. Table 1: Step-by-step design process for microprocessors and FPGAs Microprocessor This side-by-side comparison lets you quickly assess the two processes and see how similar they are. Similarities Table 1 shows the steps involved in designing embedded systems with a microprocessor and an FPGA.

We'll use the similarities to understand the basics, then discuss the differences and how to think about them. The development process for FPGAs is similar enough that you'll have no problem understanding it but sufficiently different that you'll have to think differently to use it well. This article will show the programming process used for FPGA design.ДЄs an embedded systems programmer, you're aware of the development processes used with microprocessors. Unlike microprocessors, not only the memory bits, but also the logical gates are under your control as the programmer.

Powerful tools exist to program these powerful chips. Figure 1 compares one of these microprocessors with an FPGA.ДЇigure 1: Comparison of first microprocessors to current FPGAs Today, field programmable gate arrays (FPGAs) provide single chips approaching 10 million gates of logic and 10 million bits of memory. The first single-chip microprocessors contained approximately 10,000 gates of logic and 10,000 bits of memory. Small processors are, by far, the largest selling class of computers and form the basis of many embedded systems. Here's a primer on how to program an FPGA and some reasons why you'd want to. FPGA programming step by step By Ed Klingman, Courtesy of Embedded Systems Programming (14:00 PM) URL: ДЇPGAs and microprocessors are more similar than you may think.
