Select the statement that best describes DRAM.

A state transition table for a finite state machine is given. The clock input is 100 MHz. Suppose the FSM is currently in state S0 and the inputs are AB = 10.  What will the state be after the next clock edge?  What will the output be?

Given:  The size of a memory array is 256 x 32.  How many bits does the address line have?

Given: 0100.1010 is a Q4.4 fixed-point binary number.  What is its value in decimal (ex: “3.25”, “-4.125”)? Note: 1/16 = 0.0625; 2/16 = 0.125; 3/16 = 0.1875; 4/16 = 0.25; 5/16 = 0.3125; 6/16 = 0.375; 7/16 = 0.4375; 8/16 = 0.5; 9/16 = 0.5625; 10/16 = 0.625; 11/16 = 0.6875; 12/16 = 0.75; 13/16 = 0.8125; 14/16 = 0.875; 15/16 = 0.9375

Select the answer that best completes this sentence: The amount of time that the input to a flip-flop must be stable before the clock edge to ensure proper operation is called the _______________.

A timing diagram is given for a 3-bit counter. What is the value of the count (Q2:0) at time = 145 ns?  Assume the delay from inputs changing to outputs changing is negligible.  Give your answer in decimal (ex: “2”, “7”)

Q6-C-8 points In a certain state, all license plates consist of from 4 to 6 symbols chosen from the 26 letters together with the ten digits (0-9) a) How many license plates are possible, repetition allowed? b) How many license plates are possible, repetition is not allowed?  

Given: A finite state machine has 8 states.  What is the minimum number of flip-flops required if binary encoding is used to encode the state?

Q7-C-8 points A group of 12 students is available. A team of 6 students is to be selected and then arranged in a line for a photo. In how many ways can this be done?

Convert 6.562510 to a Q4.4 fixed-point binary number.  Show all 8 bits and the binary point (ex: “0001.1000”). Note: 1/16 = 0.0625; 2/16 = 0.125; 3/16 = 0.1875; 4/16 = 0.25; 5/16 = 0.3125; 6/16 = 0.375; 7/16 = 0.4375; 8/16 = 0.5; 9/16 = 0.5625; 10/16 = 0.625; 11/16 = 0.6875; 12/16 = 0.75; 13/16 = 0.8125; 14/16 = 0.875; 15/16 = 0.9375
