Prompt: excellent, given i've read a bit of the book, and started the basics.
i've found documentation on the ISA used in the processor, though having yet found good information about the memory map alas.
i've decided to take this path this week, i'd like to simulation first, hardware second, have a working basic ISA compatible subset CPU with instructions needed to write a LED blinker. the LED can be memory/register mapped for simplicity, whatever you feel is simpler.
so it'll need the absolute basic amount of instructions to count up till a number is reached, and when the count is reached change the state of the led, so, we'll probably need a basic ALU, PC, and branching, please write the .asm that you think we'll need to execute given the ISA spec i've included, and explain each of the instructions and what they do.
please while your at it try to find out if there is a working 'assembler' ( as in, translator from .asm to actual machine code ) that i'll be able to use to generate the instruction stream.
