How about a set of standard VPs for the compiler, much like the Javilin does.

SEROUT, SERIN, PULSOUT, PULSIN, ANALOGIN, RCTIME, FREQOUT, etc. 

Something like:

INTERRUPT 200000
  VPSERIN SInPin, "T2400", array_buffer, byte_head, byte_tail, byte_bitCnt
  VPFREQOUT SFreqPin, 1000, byte_progress
RETURNINT


Start:
 IF byte_head <> byte_tail THEN
   char = array_buffer[byte_tail]
   INC byte_tail
   byte_tail = byte_tail AND $0F
   ' Do something with "char"
 ENDIF

I guess each VP would have to take the same number of cycles no matter what to keep everything sync'd.
