Design a tiny control unit for a one-address machine. In your design you must show the Instruction Register (IR) fields (op-code, addr). The op-code is 2 bits and is connected to a decoder. The outputs of the decoder are numbered 0, 1, 2, and 3 and each one of them is associated to a different instructions (0 = LOAD, 1 = ADD, 2 = STORE, and 3 = SUB). A 3- bit ring counter is used to execute the instruction in three clock ticks (T1, T2, and T3). In your design you must show IR, the decoder, and ring counter for the execution of the instruction STORE. Show, (using a box with a label for each computer component), the part of the computer that receives signals T1, T2, and T3.

Write a grading program for a class with the following grading policies: a. there are two quizzes, each graded on the basis of 10 points. b. there is one midterm exam and one final exam, each graded on the basis of 100 points. c. the final exam counts for 50% of the grade, the midterm counts for 25%, and the two quizzes together count for a total of 25%. (do not forget to normalize the quiz scores. they should be converted to a percentage before they are averaged in.) any grade of 90 or more is an a, any grade of 80 or more (but less than 90) is a b, any grade of 70 or more (but less than 80) is a c, any grade of 60 or more (but less than 70) is a d, and any grade below 60 is an f. the program will read in the student’s scores and output the student’s record, which consists of two quiz and two exam scores as well as the student’s average numeric score for the entire course and final letter grade. define and use a structure for the student reco
