We are working on a new processor, techium 5, which is going to replace the
old Techium 4. Techium 5 has new ISA with more registers, which
1. Reduces the number of memory instructions by 50 %
2. While increasing the number of simple ALU instructions by 10%
Additionally, Techium 4 has a clock frequency of 2GHzm while Techium 5 uses
3GHz.
The two processors have the same average CPI for each type of instruction—
1 CPI for simple ALU, 3 CPI for memory
2 CPI for all other instructions
A professor mostly runs a project grading script grading script on this
laptop. A run of this script, with the Techium 4 processor, resulting in
executing 50 billion simple ALU instructions, 10 billion memory instructions
, and 40 billion other instructions.
How long does this script run on Techium 4?
How long does this script run on Techium 5
