Embedded real-time kernel for our proprietary automata

Equivalent to a "Warrior Code" for our "real time embedded kernel" - author Olivier Grimbert - which turns on the HITACHI SH and our electronics cards developed internally. Colorization of the code, automatic indentation, compilation, debug ... all in 4D and 4D Write! Contactez-nous.

This real-time kernel is designed on the principle of the Forth language, but is far from it now, by its remote development tool, all the real time management, and the 32-bit aluminum. Its implementation on a RISC μ-processor, the SH, makes it a very fast language. Our last target is on the Elyn map.

32 bits address space
32 bits for maths and logics
Parameter passing through a stack
reverse polish notation
multitasking, real time clock 1 mS
interrupts management by language
interrupted serial ports, Xon / Xoff
integrated one pass compiler on board
pseudo-code decompiler
SH assembler / disassembler
debugging, trace, step ...
integration of external routines
S1S9 integration in the code
video treatments
development tool for Mac or PC
integrated language documentation

Benchmarks

1000000 0 do loop => 2 µS per loop
nop => 0,4 µS
call => 1 µS
4 5 + drop => 2 µS so 0,5 µS / instruction

Caméra QuickCam, direct DMA access, keyboard, graphics, stepper motors, LCD, loader S1S9, generic recursive menus manager, MIDI, modem, clock, and so one.
Autonomous applications génération : the program is compiled in a cmos ram saved by lithium battery (10 years).
The development tool is written in 4d, manages sources and projects, includes online help and automatically colorizes the syntax.

Here the project window with the input area, and the list of sources.
