all except the multiply (2 clock cycles) and the JMP (2 cock cycles) are
single cycle instructions.. you also have Harvard architecture for memory,
so you have EEPROM, FLASH and SRAM all seperate.. hardware USART, SPI and
bunch of other things.

You can get 16bit micros (hitachi do some interesting looking ones) which
I'm tempted to play with.
