Implementing APL concepts in Forth - Bob
Armstrong
While Forth implements an extensible dictionary, APL provides
arguably the most expressive vocabulary for implementing complex algorithms.
4th.CoSy is
working to implement a concise APL-informed vocabulary acting on dynamic
recursive list structures in Reva
Forth.

Gforth for eCOS - John E. Harbold
John will
give a give an update on his effort to port Gforth to the
eCos platform. eCos is an
embedded configurable operating system which is open source, POSIX-compliant,
real-time, and multi-threaded with a choice of scheduler.

Cortex-M4 SwiftX - Leon Wagner
We'll learn
about flash-resident SwiftX programming on the Atmel SAM4S series. Establishing
a fast coding and testing development cycle on an embedded microcontroller with
a flash-resident program requires an optimized flash loader. Leon showed the
difference between the traditional Atmel Studio approach and the Forth
approach.

64-bit Standalone Forth System - Stefan Mauerhofer
(from Switzerland)
FLOS is a 64-bit Forth project that runs directly on the
PC without an operating system. It takes advantage of the 64-bit capabilities
of modern Intel-based microprocessors and employs indirect threaded code for
the inner interpreter with a polyForth-like tasking model. Careful use of the
memory management unit allows efficient stack and heap management. In this
project, Forth is used more as a philosophy rather than a standard. The
language is extended with namespaces, a graphical user interface, and
object-oriented programming to support large software projects. The
presentation gave a brief introduction to the language and the system. The
project is still in its infancy, but a running prototype was presented.

Green Arrays - Multiple Presenters
The
afternoon session was devoted entirely to Green Arrays and their parallel
processing Forth chips. They began with a short briefing on the progress of
Green Arrays in the past year and then provided a glimpse of their plans for
the company's future. Green Arrays' engineers and partners discussed the chips
and their applications, presented high-level strategies for choreographing the
work of teams of computers in a variety of applications, as well as some
insight into lessons learned while implementing them.
