compiler C $1$ : arithmetic: $40\%,$ Memory : $30\%,$ control : $20\%.$ CPU cycle count: arithmetic: $4,$memory : $3,$ control : $2.$ clock rate : $4$ GHz $.$A different compiler C$2$ generates code that replaces some arithmetic with lookup table accesses. Specifically, it can replace $10$ arithmetic instructions with one memory access, and it can do this on $10\%$ of arithmetic instructions. For benchmark B$,$ which compiler is faster and by how much?
