Consider the following MIPS code segment that is executed on a 5-stage pipeline architecture that does not implement forwarding or stalling in hardware. (1) add $4, $1, $1 (2) add $7, $4, $9 (3) lw $2, 40($8) (4) sub $8, $1, $2 (5) sw $8, 80($2) (6) sub $2, $8, $4 (7) lw $8, 2($1) (8) add $8, $4, $2 a. [6 marks] Identify the data dependences that cause hazards. You are to use the following format to inform each dependency reported: instruction (y) depends on instruction (z) caused by register $ b. [8 marks] If the hazards identified in (a.) are to be prevented by the compiler through no-op insertions but without reordering the instructions, indicate where would the compiler add no-ops. You are to use the following format to inform each dependency reported: insert x no-ops between instructions (y) and (z). c. [6 marks] Now assume a more intelligent compiler that can move instructions in the code. Can such a compiler reduce the number of added no-ops?

Creating "smart interfaces" in all sectors of industry, government, and the public arena is one of the fastest growing hct areas. these interfaces model, interpret, and analyze such human characteristics as speech, gesture, and vision. the field of biometrics, in which humans authenticate themselves to machines, is an area of considerable interest to hct practitioners. fingerprint scans are one of the most frequently used biometric options, and this article, biometric student identification: practical solutions for accountability & security in schools, makes a case for the implementation of fingerprint scans in schools. critique the article, and answer the following questions: according to the author, what are the main benefits of adopting fingerprint scans in schools for student identification? according to the author, what are the main drawbacks of adopting fingerprint scans in schools for student identification? do you agree with the author's assessment of the pl

Auser is given read permission to a file stored on an ntfs-formatted volume. the file is then copied to a folder on the same ntfs-formatted volume where the user has been given full control permission for that folder. when the user logs on to the computer holding the file and accesses its new location via a drive letter, what is the user's effective permission to the file? a. read b. full control c. no access d. modify e. none of the above
