L5-1 Compare the source code and assembly code for a moderate-size program.

(Most C compilers will provide an assembly language listing with the -s flag.)

Can you trace the high-level language statements in the assembly code? Can

you see any optimizations that can be done on the assembly code?

L5-2 Write C code for an FIR filter. Measure the execution time of the filter, either

using a simulator or by measuring the time on a running microprocessor. Vary

the number of taps in the FIR filter and measure execution time as a function

of the filter size.

L5-3 Generate a trace for a program using software techniques. Use the trace ...
