Question

The dynamic branch prediction algorithms use

(a) Branch History Table (BHT)

(b) Branch Target Buffer (BTB)

(c) Branch History Table and Branch Target Buffer

(d) None

I got this question in a national level competition.

This question is from Netburst Microarchitecture For Pentium4 -2,  Instruction Translation Lookaside Buffer (ITLB) and Branch Prediction topic in division Pentium 4 processor of Microprocessor

Answer 1

Right answer is (c) Branch History Table and Branch Target Buffer

To elaborate: The dynamic branch prediction algorithms use two types of tables, namely Branch History Table (BHT) and Branch Target Buffer (BTB).
