You have been asked to participate in developing the requirements for an RFID-based identification card for students, faculty, and affiliates at a university. First, list 5 to 10 different uses of the card. Second, from that list of uses, detail what data the card needs to broadcast to receivers that will accomplish those uses. Third, identify uses that could be made of that data by rogue

receivers surreptitiously planted around the university campus. Which rogue accesses threaten personal privacy? In what ways? What is the degree of harm? What will be an ideal response?

A pipelined computer has a four?stage pipeline: fetch/decode, operand fetch, execute, writeback. All operations except load and branch do not introduce stalls. A load introduces one stall cycle. A non?taken branch introduces not stalls and a taken branch introduces two stall cycles. Consider the following loop.

for (j=1023; j > 0; j--) {x[j]=x[j]+2;} a. Express this code in an ARM?like assembly language (assume that you cannot use autoindexed addressing and that the only addressing mode is register indirect of the form [r0]). b. Show a single trip round the loop and indicate how many clock cycles are required. c. How many cycles will it take to execute this code in total? d. How can you modify the code to reduce the number of cycles?
