Combinational logic circuits are circuits whose outputs depend only on the present value of their inputs. The lecture on “Combinational Logic Design” introduced you to some of the common combinational logic circuits.
For your second project, you are required to Design, Implement, and Test an 8-bit Arithmetic Logic Unit or ALU. By using VHDL (Use block diagram shown below
Recommended Design Procedure:
1. Find the number of input variables and the number of required output variables. Assign them meaningful names.
2. Create a truth table that defines a relationship between inputs and outputs.
3. List the operations (Choose any Five Arithmetic and Logic Functions, in which Shifting and Comparator should be included) that you will be implementing – the more the better 4. Draw the logic diagram.
5. Implement your design using VHDL
6. Test your design by creating a test bench
Give a brief discussion of the theory of operation, including schematics and equation used, etc. This is of importance for the design oriented labs and mini-projects. You should also explain the schematics involved in your design.
4. Experimental results: (70 pts including the section on “Theory of Operation”) • Brief description of the lab experiment.
• Schematics of the circuit (from Xilinx schematic entry tool). Put your name and date on each page.
• Simulated waveform.
• Discussion of the results indicating that the circuit functions properly. It is not good enough to just give the simulated waveform. It is up to you to show that this waveform corresponds to what you expect (do not say “the simulation shows that the circuit works properly”). You need to make it clear to the reader that the circuit works properly! One convenient way is to use some of the entries in the truth table in your test bench, indicating that for each entry/input the corresponding values/outputs given by the logic simulator correspond to what is displayed in the table.
The noteworthy bookkeeping approaches characterized by FASB for the uses of bookkeeping standards and techniques have an extensive variety of general depiction. Conversely of that, basic bookkeeping strategies and evaluations that proposed by SEC just gauge a portion of the generously unverifiable and material bookkeeping approaches. FASB indicates the divulgence of huge bookkeeping arrangements ought to recognize the bookkeeping standards and the techniques that will physically influence the budgetary position, and results in various tasks, or income. They incorporate judgments, regardless of whether rule proper amongst income and resource cost amid present or future period (Codification, 235-10-50-3). In this paper, I utilized Apple yearly report for instance. In the Form 10-K/An of Apple Inc. (recorded in Jan 25, 2010) incorporate introduction and arrangement, reasonable esteem estimations, money related instruments, inventories, property plant and hardware, resource retirement commitments, altruism, remote cash interpretation and remeasurement, income acknowledgment, shipping costs, remittance for far fetched account, guarantee cost, programming advancement cost, wage charges, stock-based remuneration, publicizing costs, profit per normal offer, thorough pay, section data. For instance, Apple unveiled inventories thing at (LCM) bring down the of cost, or market, figured with FIFO (first-in, first-out) strategy. In acknowledgment thing, the Company perceives income when conveyance has happened or any powerful proof of an assention exists. In addition, in income acknowledgment thing, for various component plans which may incorporate unmistakable items that contain programming that is fundamental to the substantial item's usefulness and undelivered programming components that identify with the substantial item's basic programming, the Company allots income to all expectations in light of their offering costs (Form 10K/A, 2009). Before application, there are necessities that the basic bookkeeping assessments should meet: at the set aside a few minutes of bookkeeping gauges, the dubious supposition; another is, any sorts of evaluations utilized amid current period and changes made in the gauge should affect the money related condition really. There three components that are engaged with the bookkeeping estimation: the first is to comprehend the bookkeeping gauges; the second is to give a clearer fathoming to the monetary condition for typical financial specialists; the third is to reveal administration talked about improvement (SEC, 2002). Besides, the basic bookkeeping arrangements and assessments ought to be as the supplements of notes of budgetary proclamations, however not copy any related data that as of now exhibited. The basic bookkeeping polices revelation ought to give importance data profoundly (SEC, 2003). From the sec's goal, bookkeepers should assume unequivocally liability for the danger of assessments and changes. Additionally, bookkeepers ought to have the capacity to clarify how they turned out with the outcomes and assessments. On the off chance that last year a bank made a considerable measure of relative new advances, so the report would look great. Be that as it may, if huge numbers of those borrowers later neglected to pay, at that point the current year's report would look terrible. So for the following year, the bank administration will be required to assess what number of borrowers would neglect to pay, possibly a rate, and place it in the notes of MD&A. >GET ANSWER
