1. Describe details of the implementation of the rload and rloadx instructions, specifying for each the operation details (such as control signals asserted) at each pipeline stage.
2. Suppose the R-machine bypass logic ignored the n bit and assumed that every instruction word is valid (enabled), Describe a scenario in which this naive variant will give results that differ from those likely to be anticipated by the programmer. Outline a programming discipline that avoids the need for n.
