Mallard ECE 290: Computer Engineering I - Spring 2007 - Graded Web... file:///C:/Documents%20and%20Settings/Al/Desktop/Mallard_HW_8/Sh... 1 of 2 3/13/2007 1:08 AM Graded WebQuiz: Shift Registers You have submitted this WebQuiz 1 time (including this time). You may submit this WebQuiz a total of 10 times and receive full credit. Notes for Question #2: 1. The A i values are the flip-flop outputs; FF i has output Ai. The F i values are the flip-flop inputs. 2. The terms "circular" and "rotate" are used interchangeably. Question #1 Suppose R is a 6-bit register whose content is ABCDEF (i.e., each of A,B,C,D,E,F is either 0 or 1). Assume the shifter has the following inputs: serial input for left shift = 1 serial input for right shift = 0 Determine the content of R after each of the following instructions is executed. Note 1: Each part is independent : assume the content of R is ABCDEF prior to the execution of each instruction. Note 2: When arithmetic operations are used, assume the content of R is a number in 2's complement form.
