Example: Vector Dot Product

• Prologue

  • Initialize pointers: ar2 for a(n) and ar3 for x(n)
  • Set accumulator (A) to zero

• Inner loop

  • Multiply and accumulate a(n) and x(n)

• Epilogue

  • Store the result into Y

; Initialize pointers ar2 and ar3 (not shown)

rptz a,#39 ; zero accumulator a ; repeat next instruction 40 times

mac *ar2+,*ar3+,a ; a += a(n) * x(n)sth a,#Y ; store result in Y
