Legacy target CPUs


Because embedded projects can have very long lifetimes, we do not abandon compilers that are no longer under active development. Instead, they are made available with full source code at reduced price. The technical support level will depend on whether we can remember anything about this particular target and still have hardware for it. Consultancy is always available.


Forth 7 Windows compilers

ARM7/ARM9/
StrongARM/Xscale
Current devices have amazing performance at insanely low prices. Target code is provided for CPUs from many suppliers including NXP/Philips, Atmel, Analog Devices, ST, Intel, Sharp, Samsung, Oxford Semi and Crystal. The compiler supports both big and little endian code, 26-bit PC mode, and devices without the LDRH/STRH instructions. XCARM/70

Forth 6 Windows compilers

CPU family Comments Order code
68xxx/683xx Excellent code, a perennial favourite. XC68K/62
80x86/88 A fast 32 bit system for real-mode x86 systems. Best of class for real-mode x86 Forth systems considering speed/size trade-offs. XC3216/59
Intel 80C196 Good 16 bit workhorse. XC196/60
68HC11 Goes on and on XC68HC11/60
Z80/Z180/84Cxx Excellent 8 bit performance; easy to expand memory, interesting EZ80 cores XC180/60
H8/500 Ideal for TDS2020 target boards that have run out of memory or speed. XCH8500/60
M37700 Excellent peripheral mix. XC37700/60
Mitsubishi M74xx/38xxx For all Mitsubishi, Rockwell, and other derivatives of the 6502 core. XC6502/60
6502/C02 For all 6502 and 65C02 compatible cores XC6502/60

Forth 5 DOS compilers

Although current PCs provide no direct support for 16 bit DOS programs, these compilers can be run under DOS emulators such as DOSbox for Windows and many other operating systems.

68HC16 Good performance. XC68HC16/51
RTX2010RH
RTX2000
RTX2001
RTXcore
Supports the Harris/Intersil RTX2000, 2001 and 2010RH chips and the RTXcore for FPGAs. The compiler was the official Intersil development tool for this radiation hardened processor, and now the RTXcore VHDL clone for FPGAs is available with twice the performance. XCRTX20xx/51
TMS320C3x/4x A highly efficient DSP family XCTMS3x/51

Forth 4 DOS compilers

Although current PCs provide no direct support for 16 bit DOS programs, these compilers can be run under DOS emulators such as DOSbox for Windows and many other operating systems.
