2. (40 POINTS) Assume a 16-word direct mapped cache with b=1 word is given. Also assume that a program running on a computer with this cache memory executes a repeating sequence of lw instructions involving the following memory addresses in the exact sequence is given: 0x74 0xA0 0x78 0x38C 0xAC 0x84 0x88 0x8C 0x7C 0x34 0x38 0x13C 0x388 0x18C 2 2.A.) (30 POINTS) Show the placement of the given instruction addresses in this cache. 2.B.) (10 POINTS) Calculate the miss rate of this cache for the given list of instruction addresses. Please show your work. It is ok to use hand-drawing. If so, make sure

Which of the following is a difference between the systems development life cycle (sdlc) and extreme programming (xp)? the sdlc model has a separate planning and analysis phase, whereas xp combines both the phases into one phase.in the sdlc model, changes cannot be made to a system once it is delivered to the user, whereas the xp method delivers the system to the users and then make changes suggested by the user.the sdlc model develops an entire system at once, whereas xp uses incremental steps to improve an information system's qualitydevelopers following the sdlc model cannot go on to the next phase until the current phase is finished, whereas in xp, developers can move to any phase from the current phase.
