Parallel Processor Addressing Modes

• Scaled indexing

  • Allows for data-independent indices
  • Useful for lookup table implementation

; a2-pointer to first element of a lookup table

; Data may be of any type (here it is word)

d6 = w *(a2+[1]) ; Second element is loaded into d6

• Relative addressing
  • Allows for code independent of parallel processor

; dba automatically contains address of local PP RAM

d6 = w *(dba +[1]) ; Second element in PP RAM -> d6
