The 6502 has a stack that's stuck on Page 0 and only has 256 bytes.
Stack is page 1, zero page is its own special thing and many instructions can operate on it, resulting in fewer bytes per instruction.
Oops, yes sorry.
I think the Microchip PIC32s are bringing multicore to the embedded world so I might see more 'weirdness' now. Of course I'm seeing more high level languages in my embedded stuff (MicroPython, Lua, etc.)
PIC32s are MIPS 32, pretty cool! I've got a Fubarino dev board for PIC32, but haven't gotten around to hacking on it. Someone's got 2.11BSD running on them.
A friend of mine worked on the Arduino port to the PIC32 and it works well (I just hate the Arduino env). The port has support for parallel functions (nice). -- Linux Home Automation Neil Cherry ncherry@linuxha.com http://www.linuxha.com/ Main site http://linuxha.blogspot.com/ My HA Blog Author of: Linux Smart Homes For Dummies
