Introduction

In this two week laboratory exercise, you will implement a filter to meet a given set of specifications. Unlike previouslabs, you will be graded on the basis of the efficiency of the system that you implement on the DSP. There are two broadways in which you are to optimize your low-pass filter system:

  • We have left the way in which you implement the low-pass filter system completely open and you are free tochoose the method you think will be the most efficient. In filtering techniques , we describe three possibilities:
    • use of an IIR filter
    • overlap-and-add or overlap-and-save using the FFT to perform fast convolution
    • use of multi-rate and multiple filter stages to lower the overall order of the filters required to meetthe specifications.
  • Once you have decided on the overall system for your filter implementation and have verified that it will meetthe given set of filter specifications through simulation, there are many opportunities for optimization in the actualcode that you write for the DSP. You may want to use C in your implementation, but consider the efficiency penaltyincurred from that choice. Use of the various parallel instructions available on the DSP, e.g. ld||mac and st||ld , may yield greater efficiency. Of course, classical optimizations suchas loop-unrolling or the precomputation of data may improve efficiency.

In this lab, you are required to do the following:

  • Choose two techniques described in filtering techniques and answer the prelab questions for those two techniques.
  • Write a complete MATLAB simulation for one filtering technique. You must demonstrate that your simulation meetsthe filter specifications given in the filter specification .
  • Implement the technique that you simulated on the DSP and optimize the system to make it as efficient as possible.You will be graded on the efficiency of your implementation.

A detailed break-down of how you will be graded and the various due-dates can be found in grading .

what is fullerene does it is used to make bukky balls
Devang Reply
are you nano engineer ?
s.
fullerene is a bucky ball aka Carbon 60 molecule. It was name by the architect Fuller. He design the geodesic dome. it resembles a soccer ball.
Tarell
what is the actual application of fullerenes nowadays?
Damian
That is a great question Damian. best way to answer that question is to Google it. there are hundreds of applications for buck minister fullerenes, from medical to aerospace. you can also find plenty of research papers that will give you great detail on the potential applications of fullerenes.

so some one know about replacing silicon atom with phosphorous in semiconductors device?
s. Reply
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.
