DIOS Forth
(c) 2012 Luboš Pěkný
  DIOS Forth 1.0 is first, simple, version 32-bit Forth for PIC32mx795, module Duinomite mini.
Words can be compiled to RAM or flash. RAM for testing or often changed words, flash for embedded applications. Words are from Forth-83, ANS Forth, not all implemented, writed in C MPLAB.

  DIOS is low level layer (Device Input Output Services), interrupt buffered routines for service devices, pheripheries on chip PIC32. EMIT call directly UART TX, but is posible call DEFER or DIOS services. Now are supported devices: timer1, uarts, I/O pins, AD converter, PWM.

  Maximal speed Forth virtual machine for 80MHz PIC32 is 4 Mps (as 4 millions forth words per second), empty DO LOOP is 2.3 Mps (millions cycles per second). For comparison with other systems to see benchmark tests in directory \bench.

  Used memory: 16kB Duinomite boot, 43kB flash, 48kB RAM (12kB uarts, 16kB dictionary, 16kB RAM).
  Free memory: about 440 kB flash, 80kB RAM (PIC32mx795).

  Compiled with C MPLAB 8.83, C32 2.02, gcc 4.5.1. Tested with DUINOMITE-MINI (PIC32MX795F512H 80MHz), uart2 115200 Bd, windows terminal Forfiter.exe 1.6 .
