LDUR is instruction with the longest latency on the CPU from Section 4.4 (page 271-283). If we modified LDUR and STUR so that there was no offset (i.e., the address to be loaded from/stored to must be calculated and placed in Rd before calling LDUR/ STUR), then no instruction would use both the ALU and Data memory. This would allow us to reduce the clock cycle time. However, it would also increase the number of instructions, because many LDUR and STUR instructions would need to be replaced with LDUR/ADD or STUR/ADD combinations.
What would the new clock cycle time be?
