Question

Branch predictors can have different configurations as follows: 1. GAg: 1 global history register and 1 global prediction table 2 2. GAp: 1 global history register and 8 per-address prediction tables 3. PAg: 8 per-address history registers and 1 global prediction table 4. PAp: 8 per-address history registers and 8 per-address prediction tables We will use the following format for the configurations. -bpred:2lev <l1size> <l2size> <histsize> Configurations: N, M, W N # entries in first level M # entries in 2nd level (# of shift register(s)) (# of counters, or other FSM) W width of shift register(s) (# of bits in each shift register) Sample predictors: GAg: 1, M, W where M = 2$^W$ GAp: 1, M, W where M = C$\times$ 2$^W$, C is # of per-address prediction tables PAg: N, M, W where M = 2$^W$ PAP: N, M, W where M = N$\times$ 2$^W$ Requirements: Show the configurations for the above 4 branch predictors using N, M, W and write in the report. Assume for each branch predictor, the number of predictors (saturation counters) is 512. (No simulation is required for Part B)

          Branch predictors can have different configurations as follows:
1. GAg: 1 global history register and 1 global prediction table

2. GAp: 1 global history register and 8 per-address prediction tables
3. PAg: 8 per-address history registers and 1 global prediction table
4. PAp: 8 per-address history registers and 8 per-address prediction tables
We will use the following format for the configurations.
-bpred:2lev <l1size> <l2size> <histsize>
Configurations: N, M, W
N # entries in first level
M # entries in 2nd level
(# of shift register(s))
(# of counters, or other FSM)
W width of shift register(s) (# of bits in each shift register)
Sample predictors:
GAg: 1, M, W where M = 2$^W$
GAp: 1, M, W where M = C$\times$ 2$^W$, C is # of per-address prediction tables
PAg: N, M, W where M = 2$^W$
PAP: N, M, W where M = N$\times$ 2$^W$
Requirements: Show the configurations for the above 4 branch predictors using N, M, W and
write in the report. Assume for each branch predictor, the number of predictors (saturation counters)
is 512. (No simulation is required for Part B)
