What's the schematic of the 4-bit multiplier that has
two 4-bit inputs and an 8-bit output

with pure combinational logic? Can you draw the circuit?

I have impleted the 4 bit multiplier by using the 4 bit full adder and AND gates which are purely combinational. In this implementation we are giving partial product terms as inputs to 4 bit adder at each state and final product is nothing but sum of all four partial products obtained during multiplication of (A3 A2 A1 A0) *(B3 B2 B1 B0). thank you..

Design and test a 4-bit rotator that has two inputs: A and
rotamt, and two outputs Yleft and Yright using (System) Verilog.
The rotation amount (number of bits to be rotated) is given in
rotamt and the output of left and right rotation will be in Yleft
and Yright, respectively.

3. The lecture notes show a 4-bit by 4-bit multiplier. If the
same approach is used to make an 8-bit by 8-bit multiplier:
a) How many AND gates are required?
b) If each AND gate has 1 ns of delay and each adder has 5 ns of
delay, what is the total delay for the 8-bit by 8-bit
multiplier?
c) Can you think of a better way to array the adders to reduce
the delay?

Design a 4-bit multiplier by using 4 bit full adder and write a
verilog code.

design a 4 bit comparator that compares
two numbers of 4 bits. the output should be < > or =. however
you're only limited to using multiplexers or full adders. any help
on how to draw this will be appreciated

Write the code to compare two 8-bit buses, a and b. The output
signal is agrb for “a greater than b.”

Using JK flipflopDesign a multisim schematic for a 4 bit
synchronous counter that counts numbers in Gray code. 4 bit Gray
code is as follows: 0000 0001 0011 0010 0110 0111 0101 0100 1100
1101 1111 1110 1010 1001 1000

VHDL Code: Design a 16-bit 4-to-1 multiplexer using data-flow
implementation style. Data inputs and output should be 16-bit
vectors. In your test bench, you should include enough number of
test cases to show the correctness of your design.

2. A sequential circuit has two pulse inputs, x1 and x2. The
output of the circuit becomes 1 whenever the pulse sequence
x1x1x2x2x2x1 is detected. The output then remains 1 for all
subsequent x1 pulses until an x2 pulse occurs.
(a) Derive a minimal state table describing the circuit
operation. (Here you need to define the states and then perform
state reduction).
(b) Synthesize the circuit using SR latches in the master rank.
(Here, you need to make state assignment,...

Write a MATLAB function named myaccel that
accepts three inputs and has a single output.
Inputs:
a list of time values
a list of position values
a single time value.
Output:
a single number which is obtained by numerically
differentiating position with respect to time twice
(forward difference method) and then interpolating
the results based on the third input.
Example:
time=0:10;
position=time.^3;
myaccel(time,position,2.8) % should return 22.8

Write a program whose inputs are two integers, and whose output
is the smallest of the two values.
Ex: If the input is: 7 15
output is: 7
passed through command line
