Properties of different architectures

Software architectures are the blueprint of a software system. They consist of all components involved in a system, relations between various components, the environment of operation, and the principle used in designing the software. In other words, software architecture shows the organization of different software structures and helps understand their behavior.

Question

Derive and simplify the boolean expression for bit 0
of the next state.

Up Counter Finite State Machine
Construct the Finite State Machine repressentation
for an up counter with a cycle length of 4 - i.e. a
circuit that counts 0 – 1– 2 – 3 (output as a binary
value, obviously) with successive clock pulses, and
then starts over.
The external output is the 2-bit count. The only
external input is R, a reset pulse: when R = 1 it
resets the next count to 1 (not zero, as in the
practice exam), no matter what the current state;
when R = 0 it keeps counting (i.e. the system
transitions to the next state in sequence).

Consider a circuit designed as follows: • one 1-bit register (like those discussed in class), with an attached clock • one not gate • wire A connects the register's ouput and the not's input • wire B connects the not's output and the register's input If we put a 1 onto wire B: A. wire A gets a 0 immediately B. wire A gets a 0 after the short delay it takes the gates in the register to finish work C. wire A gets a 0 after the next clock tick D. wire A gets a 1 immediately E. wire A gets a 1 after the short delay it takes the gates in the register to finish work O F. wire A gets a 1 after the next clock tick
Design a Moore FSM for a Sequence Derector that detects five consecutive bits of "zero" in the input stream of bits, labeled x. The output z equals 1 if, during five consecutive clock cycles, the input x was equal to "zero". Once the sequence is detected, the FSM returns to the initial state S0. Add an asynchronous reset, active low, to the FSM.
Design a finite state machine (FSM) with one input A and two outputs S and L. The FSM should detect whether a short or a long pulse appears on input A and assert output S in case of a short pulse and assert output L in case of a long pulse. A short pulse is defined as a pulse that lasts up to a single state duration and a long pulse is defined as a pulse that lasts for more than one state transition. Draw the algorithmic state machine (ASM) chart of your FSM design.
A digital counter is a device that generates binary numbers in a specified count sequence. The counter progresses through the specified sequence of numbers when triggered by an incoming clock waveform, and it advances from one number to the next only during the occurrence of a clock pulse. The counter cycles through the same sequence of numbers continuously so long as there is an incoming clock pulse.

Suppose we wish to design a car security system that operates as follows: • There are only two states: "siren off" and "siren on" • There is one combinational output: 0 - lights not flashing or 1 - lights flashing. • There are three combinational inputs: M(master), D(door), and V(vibration). Use the names M, D, and V for these inputs in the given order MDV. • M: 0 - off, 1 - on • D: 0 - door closed, 1 - door opened • V:0 - no vibration detected, 1 - vibration detected The circuit works as follows: • If the siren is currently off, it is turned on and the lights flash when the master is on and either the door is opened or vibration is detected. (This is a regular or, not an exclusive or). • If the siren is currently off, it will remain off and the lights will not flash when either the master remains off or if the master is on but neither the door is open not vibration is detected. • If the siren is currently on, it will remain on and the lights will flash as long as the master is on. •…
One way to think of logic gate types is to consider what input states guarantee a certain output state. For example, we could describe the function of an AND gate as “Any low input guarantees a low output.” Identify what type of gate is represented by the following phrase: “Any low input guarantees a high output.”
I believe this problem is from computer systems/architecture. PLEASE TRY YOUR BEST. I NEED TO UNDERSTAND THIS PROBLEM I need you to design a digital logic circuit as a read only memory (ROM) [Decoder + OR gates]. A ROM accepts a three–bit number (x2 x1 x0) and generates an output binary number equal to the input squared + 2. Here is the equation: A = x2 + 2, with input (x) : 0 ≤ (x) ≤ 7 (a) Try to set–up the truth–table [Binary inputs: (x); Binary outputs: ..., A2, A1, A0] (b) What is the size of the initial (unsimplified) ROM ? (c) What is the size of the final (simplified) ROM ?
Implement a 32-bit shifter. Input: x (32 bits), c (5 bits), and op (2 bits). Output: y. This shifter should shift the input number x by c bits according to the shift operations indicated by op: op = 0 left logical shift, op = 1 right logical shift, op = 2 right arithmetic shift, and 3 op = 3 left circular shift. For example, if x=0x80000001 and c=4, the value of y should be 0x00000010 if op=0, 0x08000000 if op=1, 0xF8000000 if op=2, and 0x00000018 if op=3. NEED VERILOG CODE! Please answer the Right question.
