FEATURES

“Real-Time Conflicts”
by Jonathan Bromley.
With all the talk about MIPS and MFLOPS, you'd think that high-performance designs would simply be a matter of choosing a fast enough RISC chip. Despite the hype and hoopla experienced developers know that “very fast” and “real time” are rarely synonymous. The choice of a processor should depend on your software's demands; some RISC processors will fit better than others.

“Inside a Real-Time Kernel”
by Tom Barrett and Mike Wood.
A real-time executive or kernel can save you a lot of development time—if you know how to use what you've got. Here's an overview of the architecture and functions of MCX-11, Motorola's freeware real-time executive for the 68HC11.

“Forth Machines”
by Jack Woehr.
Forth's most visible success these days seems to be in hardware; a number of companies have recently launched microprocessors designed with a stack architecture. These new chips share the characteristics of being simple in design and fast in execution. Outside of the normal academic and RISC channels, the developers of these new processors have stories and architectures as unusual as you'll find in embedded systems.
