Loop:

addi X$9,$ X$9,\backslash (1\backslash$quad $//\backslash )$ increment loop index: k $=$ k $+1$

sub X$14,$ X$13,$ X$9//$ test loop index: if limit $>$ k then X$14!=0$

addi X$10,$ X$10,4//$ compute loop body: $\backslash (\backslash$mathrm$\{$x$\}=\backslash$mathrm$\{$x$\}+4\backslash )$

sub X$11,$ X$10,$ X$9//$ compute loop body: $\backslash (\backslash$mathrm$\{$y$\}=\backslash$mathrm$\{$x$\}-\backslash$mathrm$\{$k$\}\backslash )$

CBNZ X$14$ Loop $//$ loop$-$body is done; goto loopback point

Exit:

For a loop like this, which type of branch predictor would be more accurate?

Assume X $9$ starts at $0$ and X $13$ contains $20.$ What is the accuracy of this predictor?
