Write an ARM assembly program to convert temperatures from Celsius to Fahrenheit or from Fahrenheit to Celsius. Here are the two formulas for your reference. Use variable to read and store values, you can initialize any integer value into the variables (Do not expect decimal results we are only doing integer operations). C = 5 × (F − 32) / 9 F = (9 × C / 5) + 32 Name the file TempConvert.s add the below commenting statements in the program ;Name: ;Date: ;Give which expression you use Please use LDR/STR
Suppose we have three processes P0, P1, and P2. Process P0 executes statement S0 and process P1 executes statement S1 and process P2 executes statement S2. Use wait and signal to ensure the following: S2 is always executed before S1 and S1 is always executed before S0S0.
P and Q are two processes that share a set of variables that is common. The variable includes: seq, tA and tB: Before either process starts to execute, variable seg initially has the value 10. State the possible sets of different values of seg when both processes have finished executing. Provide an order of execution of statements from processes P and Q that would produce each of the values you give. Justify your answer in detail. ...
