RTXcore


The RTXcore is a VHDL clean-room implementation of the Intersil RTX-2000 for FPGAs. It runs the same instruction set, but twice as fast on a Xilinx Spartan. An an on-chip UART as well as the original peripherals are provided. You can download the RTXcore product brief.

The MPE RTXcore System provides all the tools you will need to generate an application for the RTXcore processor. This system is in several parts:

  1. RTXcore EVB (Part No. RTXCOREEVB) includes 40/20MHz RTXcore in a Xilinx Spartan 2E with 512k Flash, 512k SRAM an on-board Forth compiler and the AIDE support shell.
  2. MPE Forth 5 for the RTX (Part No.XCRTX000/51).
  3. VFXC RTX C compiler (Part No. VFXCRTX). This compiler is a Windows hosted tool chain. For further details, see below and download the VFX C manual in PDF form (approx 670kb).

Ports of the RTXcore to other FPGAs such as the Actel/Microsemi devices are available to special order.


VFXC RTX C compiler


A C compiler tool chain for the Intersil RTX2010RH. This compiler was developed to overcome major restrictions in other C compilers for this CPU. VFX C supports the full address range of the CPU and produces good quality code, although because of the CPU architecture the code is not as good as that produced by the MPE Forth 5 compiler.

This compiler is a Windows hosted tool chain. For further details, please download the VFX C manual in PDF form (approx 670kb).


RTX Forth 5 compiler


Supports the RTX2000, RTX2001 and RTX2010RH chips plus the MPE RTXcore for FPGAs. The compiler was the official Intersil development tool for the radiation hardened RTX2010RH processor. See cross compiler page for more details of MPE Forth cross compilers.

The compiler is a 16 bit DOS application. 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.
