CSE 260 – Digital Computers: Organization and Logical Design Midterm Jon Turner 2/28/2008 1. (10 points). The figure below shows a simulation of the washu-1 processor, with some items blanked out. Fill in the blanks below with the correct value from the corresponding labeled blank in the simulation output. The instruction set appears at the bottom of the page.

(8 points) Draw a transistor-level diagram (using n-FETs and p-FETs) of a NAND gate with 3 inputs, A, B and C. Suppose all three inputs are high initially and then A goes low, causing the output of the NAND gate to go from low to high. Let tLH be the time for this high to low transition. Now, suppose that input A..
