MIT is using Fuzzy Logic to analyze cell function.

C macros are very useful, but a little taxing for both compiler writers and programmers.

I just read Jack's editorial on Embedded.com on the RS08 processor. This is a fun little processor.

We did some work on the instruction set design on this processor, and wrote a C compiler for the RS08. This is a remarkable little processor that, in the end, outperformed many people's expectations (including mine).

Jack Ganssle's latest column in embedded.com reminds us that there is still life in 8-bit architectures.

He mentions the Freescale RS08, which is supported by our C6808 Code Development System.

UPDATE: Jack cites an article on Circuit Cellar by Tom Cantrell, who also talks about RS08.

We've started to get some requests for header file support for ICD3, Microchip's new In-Circuit Debugger. There are some differences between ICD3 and previous generations of ICD. These differences are reflected in the device header files Byte Craft Limited issues for MPC.

If you're using MPC with MPLAB and ICD3, please contact Byte Craft Limited for more information about obtaining updated header files.

We've just posted a new paper that compares IEC 61131 fuzzy logic constructs and Fuzz-C additions to C for embedded systems. If you're moving from programmable logic controllers to C for embedded systems, this paper shows the similarities and differences between the two.

Read the paper here.

There's an active discussion about optimization and debugging going on on comp.programming and comp.compilers.

C Traps and Pitfalls by Andrew Koenig is an interesting compilation of C-isms: quirks of the C language that can impact the programs you write.

This article gives a plain-language way to read type declarations.

This is the start of an interesting discussion on loop unrolling as a compiler optimization. I summed up our thinking on it:

Application code usually was very clear and almost always right
in their timing choice of straight line vs loop implementation. Rolling
up straight line code and unrolling loops more often than not
interfered with a conscience choice a developer made.
