(25 points) Consider the following ARM program. Trace the values of the registers shown as they change during program execution. Also, trace the writes to memory by the STR instruction There may be unused columns or rows in the tables. If you need to add columns or rows, you may do so. DCD 1 reserves one word of storage and sets it equal to 1. SPACE 3 reserves 3 bytes of memory but does not give those bytes a value. 10.
