Pages 5 & 6: from quarter 2: instruction set analysis and cpu architecture 15 points in two parts

we need to develop an instruction set, formats, and cpu architecture to support the following operations:

r3 < r1 op r2: 32 instructions

r1 < r1 op r2: 32 instructions

mem < r1: 32 instructions

r2 < r1 op mem: 16 instructions

mem < r1 op r2: 16 instructions

the machine has 8 general purpose registers, each 16 bits in size. memory is accessed by a base plus displacement of 16 bits.

Line joining liquid phase with liquid and solid phase mixture is known as: a) liquidus b) solidus c) tie line d) none of the mentioned

During a steady flow process, the change of energy with respect to time is zero. a)- true b)- false

A3-mm-thick panel of aluminum alloy (k 177 w/m-k, c 875 j/kg-k and ? = 2770 kg/m) is finished on both sides with an epoxy coating that must be cured at or above t,-150°c for at least 5 min. the production line for the curing operation involves two steps: (1) heating in a large oven with air at ts,0-175°c and a convection coefficient of h, 40 w/m2. k, and (2) cooling in a large chamber with air at 25°c and a con- vection coefficient of he 10 w/m2.k. the heating portion of the process is conducted over a time interval te which exceeds the ime required to reach 150°c by 5 min (h = r + 300 s). the coating has an emissivity of ? = 0.8, and the temperatures of the oven and chamber walls are 175 and 25°c, respectively. if the panel is placed in the oven at an initial temperature of 25°c and removed from the chamber at a safe-to-touch tempera ture of 37°c, what is the total elapsed time for the two-step curing operation?
