Challenge Problems
Push your limits with advanced challenges
Suppose a CPU has an instruction that multiplies by two faster than a typical multiplication instruction. If your assignment code includes a lot of multiplications by two, how might you adapt your instruction selection to use the specialized instruction instead?
💡 Hint: Consider how you would replace a common operation with a more efficient one.
If a program's addressing mode requires frequent updates to a data structure in memory, how might that impact your choice of addressing mode in instruction selection?
💡 Hint: Think about how often the program needs to access the data and the implications that has.
