The IA$-32$ processors with multi$-$media extensions include $64-$bit MMX registers. The contents of registers MM$2$ and MM$4$ are shown below:

MM$2$ contains $0$x$0$A$1$A$1$ABA$5$A$6$A$7$A$8$A

MM$4$ contains $0$x$1$B$2$B$3$B$4$B$4$B$5$B$6$B$8$B

Use hex to show the $64-$bit pattern produced in register MM$2$ when the following IA$-32$ instruction is executed:

PSUB MM$2,$ MM$4$
