Grass Mix Wrigley Pasture Mix Requirements No more than 50% tall fescue At least 20% mustang fescue At least 30% bluegrass At least 30% mustang fescue No more that 20% tall fescue DuroTurf At least 50% but no more than 70% tall fescue At least 10% bluegrass Ed's Feed and Seed creates three custom grass mixes it sells in their retail stores. These mixes are made from three types of seed they purchase from a supplier: tall fescue, mustang fescue, and bluegrass. Requirements for the custom mixes are in the table at the left. Ed's want to produce 1200 lbs of the Wrigley Mix, 900 lbs of the Pasture Mix, and 2400 lbs of the DuroTurf Mix for the coming growing season. Ed's costs for the purchased seeds are $1.70/lb for tall fescue, $2.80/lb for mustang fescue, and $3.25 for bluegrass. Ed wants to know how many pounds of each seed type to purchase to minimize cost. Create a spreadsheet model and use Solver to determine how much seed of each type to purchase. The objective function, decision variables, and constraints should be clearly documented in the spreadsheet model. Write a sentence to summarize the solution. hint: minimum cost is $10,124

QUESTION 2 Which of the following choices justifies the need for Direct Memory Access (DMA)? More Interrupts, better performance Increases CPU clockspeed Less CPU involvement Less memory waste QUESTION 3 Generally speaking, a microkernel Operating System is more stable than a monolithic kernel. True False QUESTION 4 Choose the correct answer: One disadvantage of the layered kernel design is its maintainability. Generally a kernel with a built-in driver running is less reliable than the same kernel loading the driver as a module. The modular approach to kernel design requires an object oriented programming language. Generally the overhead of message passing inside a monolithic kernel is higher than a microkernel. QUESTION 5 Choose all the correct answers: ? A. If there is no entry in the kernel process table for a parent process, but the child is still running, that child becomes an orphan process. ? B. All the processes in a system become become zombies at some point. ? C. There is no entry for a zombie process in the kernel process table. ? D. If a child process is still running, but the parent process exits without calling wait(), the child becomes a zombie process.

Design a sequential circuit with a 2-bit unsigned binary integer input N (represented as input bits $N_1$ and $N_0$) and a 1-bit output Z. The circuit compares the current input to the previous input. If the current value of N is greater than the previous value of N, then Z=1. If the current value of N is less than or equal to the previous value of N, then Z=0. The circuit utilizes two D-Flip-Flops with outputs we will refer to as $P_1$ and $P_0$. (Hint: States are used to remember inputs) a. Draw the state diagram, derive the state table, and determine the D-Flip-Flop input equations and output equations. b. Implement the circuit using two D-Flip-Flops and required logic gates to implement the input and output equations, assume the complements of the inputs are available. You may use AND/OR logic, as NAND logic is not required. c. Is this a Mealy Model Circuit or a Moore Model Circuit?
