Hi! As an interesting exercise I'm going to recreate a little computer, whose design has been published on pages https://sites.google.com/site/retroelec/home
There is a statement: "An ATMega microcontroller is a Harvard architecture machine. So to be able to load and run arbitrary code without reprogramming the flash memory the code has to be interpreted. Therefore the ATMega emulates a 6502 processor (-> von Neumann architecture)." The 6502 emulation the author created is pretty interesting thing, but I would to use his design under Forth control, if possible - although I'm aware, there'll be a need to add video routines etc. on my own, and I hope to create all this exactly using Forth, not Atmel's assembler. So my question is: is it possible for AmForth to use the entire external SRAM area for both data and my own new words? You know, what I'm after: to have "basic" Forth system burned into FlashRAM, and then - as usual - to interactively develop the software for the little machine using that 128 KB SRAM the guy selected for his design. Will it work the way I described? -- Z. ------------------------------------------------------------------------------ Dive into the World of Parallel Programming.
