How to Create Jump Tables via Function Pointer Arrays in C and C++

Jump tables, also called branch tables, are an efficient means of handling similar events in software. Here's a look at the use of arrays of function pointers in C/C++ as jump tables.

How to Choose an C Compiler for Embedded Systems

Let's face it, there's nothing sexy about the topic of cross compilers. Embedded programmers couldn't get the job done without one, but spend very little time thinking about how they work or how they could make our work easier.

Efficient C Code for 8-bit Microcontrollers

The 8051, 68HC11, and Microchip PIC are popular microcontrollers, but they aren't necessarily easy to program. This article shows how the use of ANSI C and compiler-specific constructs can help generate tighter code.

Java Compilers for Embedded Systems

While most software developers have been praising the advantages of Java programming, embedded developers have been sitting idly by, waiting for a Java implementation that would complement their non-standard environments. The wait may soon be over. Java batch compilers and toolsets are starting to emerge, and may make using Java in your next project a more realistic option.

How Reconfigurable Computing Works

Designers of embedded systems face three significant challenges in today's ultra-competitive marketplace. Products must always: do more, cost less, and arrive to market faster. Fortunately, new flexible hardware design techniques are emerging from the study of reconfigurable computing.

How to Design Safer Systems via Better User Interfaces

The information that a user gets from a life-critical system may spell the difference between a slight mishap and a serious accident. This article addresses the issue of safety in the design of a user interface.

Kaffe: A Compact Open Source Java Virtual Machine

Quite a few embedded programmers are considering adopting the Java programming language. But it's not as easy to run Java programs in an embedded environment as you might think.

How to Use Java in Embedded Systems
