Consider the use of multi-level hot-cold bits in implementing a replacement algorithm for a set-associative cache with 2p ways and S sets. This is an approximation of the LRU policy that marks the most recently assessed way as hot, and the other one as cold (for a 2-way set-associative cache). This mechanism can be extended to more than two ways by providing multiple levels of hot-cold bits. For example, for a 4-way cache the victim is determined as the cold way of the cold pair. Required:
a. What is the total number of hot-cold bits for each set in this cache?
b. What is the total number of hot-cold bits in the cache?
c. At the end of the fifth access in this sequence (to Way 1), what are the settings of the hot-cold bit?

You need to design a circuit that implements the functions in the following table: s0 s1 function0 0 a + 10 1 a – b1 0 a + b1 1 a – 1s0 and s1 are 1-bit control inputs to select the function of the circuit. inputs a and b are 4-bitnumbers in 2s complement form. the output is also a 4-bit number in 2s complement form.you are allowed to use only one ttl 7483 4-bit adder to implement all the functions. but anynumber of other components (except the adder) can be used.hint: design a combinational logic circuit to modify the input b and the “carry input” of theadder depending on the control inputs s0 and s1.important: lab grade will depend on the working of the circuit & will be checked of by your labinstructor.1. is the output valid for the following input combinations: a. s0 = 0, s1 = 0, a = 7, b = 3? b. s0 = 0, s1 = 1, a = 7, b = 3? c. s0 = 1, s1 = 0, a = -4, b = -5? d. s0 = 1, s1 = 1, a = -8, b = 6? 2. what is the range of inputs (for both a and b) that will produce the valid output for all the functions?
