Reducing Branch Penalties

Reducing Branch Penalties

Reducing Branch Penalties. We saw in chapter 3 static approaches to deal with branch penalties (assuming taken or not taken branches, using the branch delay slot) Here, we will examine dynamic hardware oriented approaches: branch-prediction buffer two-bit prediction scheme
