from what i know all PICs, AVRs and 8051 derivatives are 8-bit microcontrollers. right??? but then the Microchip Midrange reference manual states that PICs are grouped by the size of their instruction word which are Base Line---12-bit instruction word, Midrange---14-bit instruction word, High End---16-bit instruction word. now what does that mean? should 8-bit microcontrollers have 8-bit instruction words?
i remember the term "instruction word" in the VLIW (very long instruction word) does this have something to do with that.
i remember that i read somewhere that there are CISC processors with a complex instruction set and then there are RISC processors with a reduced instruction set and then there are VLIW processors which have very long instruction words.
so are PICs actually VLIW based microcontrollers or am i just babbling about things i dont know :lol:
