Tutorial 11: Processor Part 3 and Arithmetic
------------


Question 1
###########
Given the set of instructions below, answer the following:


1. Indentify the data dependencies.
2. Draw a time diagram showing the clock cycles each pipelined stage takes for each instruction (see slide #65 in lecture #6), in the following two scenarios:  

 * The processor has no forward paths.
 * The processor has a forward path from :code:`Rz` to the input of the ALU and another path from :code:`Ry` to the input of the ALU.
