Question
The Cortex MO Thumb assembly subroutine below, named Exp, is used to compute the expression A power of where A and are two integer values which are allocated to registers and respectively and the result is stored in register
Note; As a reminder, all Cortex Mo instructions take one clock cycle, except unconditionat Branch instructions and conditional branch instruction if they are TRUE which take two clock cycles
Questions:
Marks How many CPU clock cycles would it take for the subroutine to be executed to compute the expression
show steps
Total number of clock cycles Cycles
Marks Same question as above in order to compute the maximal value of without causing an overflow.
show steps
Note: First, you need to find the value of A before determining the number of clock cycles.
