5. Assume a 4-bit arithmatic pipeline which performs 4-bit fix point (integer) addition, realizing 1- bit of addition in each stage of pipeline process. Explain and show how this pipeline system can be modified to perform multiple of 4-bit computations (like 8-bit, 12-bit, etc.) without increasing the stage (dept) of the pipeline. 5.
