Description
1. Assume that, today, a wafer containing 120 processor dies
costs 10000$. The yield decreases by 10% at each year while
the wafer cost also decreases by 20% at each year. Then, what
will be the cost of a single chip manufacturing after 4
years? Show your computations.
2. A compiler designer wants to compare the performance of two
different compilers he designed. The compilers are generating
MIPS machine code from a C program. He compiles the same C
program using the two compilers.
a. According to the tables below, find which compiler is
better and by how many times it is better than the other?
R-type (x106) I-Type (x106) J-Type (x106)
Compiler A 50 10 2
Compiler B 80 5 1
R-type I-Type J-Type
Required Cycles 2 4 3
b. What must be the clock speed of the processor so that the
program compiled with the better compiler executes in
100ms?
