Abstract:
A time-domain RS (Reed-Solomon) encoder was studied in this paper. Firstly analyzed coding theory of RS codes under the finite field, and focuses on the implementations of constant coefficients parallel multiplier under regular basis. On this basis, designed the encoder of RS (255,223) symmetrical structure in the Quartus7.0 build environment using the symmetry of polynomial coefficients, and use Matlab to prepare RS encoder debug and procedures verification, finally, obtained simulation results with the ModelSim5.8. The results show that the encoder is in good condition, and speed and occupancy characteristics of the hardware resources are limited compared with the existing type design.

I. Introduction
RS code is short for Reed-Solomon encoder, which is a kind of non-binary BCH codes, and is particularly applicable in correcting burst errors. Since I.S. Reed and G. Solomn proposed RS code in the paper determining constant research and improvement of their algorithm, with the purpose to increase throughput and reduce hardware resources and identify suitable VLSI implementation structure.

Using Incisive/NCSIM you can write models the way you suggested, using SystemC
constructs at the boundary and coding the functionality in C or C++. You can
load objects dynamically. You can use STL provided that you are using a
version of Incisive/NCSIM in which the SystemC library was compiled using
STL--older versions did not and you may have trouble if you mix old and new
styles. SystemC uses QT (I assume that means QuickThreads) internally--I don't
know what happens if you link in another QT implementation on top of it. The
graphics library should work fine--our DAC demo used X and the graphics worked
in both NCSIM and OSCI.

Abstract
Data encryption has become a crucial need for almost all data transaction application due to the large diversity of the remote information exchange. A huge value of sensitive data is transferred daily via different channels such as e-commerce, electronic banking and even over simple email applications. Advanced Encryption Standard (AES) algorithm has become the optimum choice for various security services in numerous applications. Therefore, many researches get focused on that algorithm in order to improve its efficiency and performance. This paper presents a survey about the cutting edge research conducted for the AES algorithm issues and aspects in terms of developments, implementations and evaluations. The contribution of this paper is targeted toward building a base for future development and implementation of the AES algorithm. It also opens door for implementing the AES algorithm using some machine learning techniques.

My Modelsim libraries are compiled.I have the
unisim,simprim,XilinxCorelib libraries compiled and they are under the
directory

C:\modeltech5.7g\xilinx_libs\unisim
C:\modeltech5.7g\xilinx_libs\simprim
C:\modeltech5.7g\xilinx_libs\XilinxCoreLib

Earlier the libraries were pointing to Xilinx Libraries and hence I
was seeing those errors.Now I see new errors like...

# ** Error: inrom_translate.vhd(641): Unknown identifier: init.
###### inrom_translate.vhd(653): INIT => '0'
# ** Error: inrom_translate.vhd(653): Unknown identifier: init.

Hi Vikram,

This is my second message...I figured out the error and thought I
would reply here just in case some one else encountered the same issue

"Component is not bound/unbound" warnings come (as you said) when
Modelsim cant find the simprimlibraries.I had the libraries compiled
as I said but I was pointing to the wrong ones.

I needed to point to the one under C:\Xilinx6\vhdl\mti_se\simprim
instead of C:\Modelsim5.7g\xilinx_libs\simprim..

As soon as I fixed this, I got results as expected...Thanks for the
guidance.Now I can proceed with my design!!

Best Regards,
Sridhar

PROJECTS:
1. SIMULTANEOUS DATA TRANSFER OVER PERIPHERAL BUS USING CDMA TECHNIQUE
Description:
This project is mainly developed for increasing the speed of chiplevel data
transmission.So I used CDMA technique in chiplevel data transmission to
reduce the time consumption of data transmission. CDMA (code division
multiple access) coding was developed using Verilog HDL (VHDL) according to
the architeture of CDMA. Modeled design has been synthesized and
implemented on FPGA family of Spartan 3E (XC3S500E) using Xilinx ISE.

the architecture. Simulated the design using ModelSim. Analyzed the results
wheather it met required results or not. Language Used:
VHDL
Tools Required:
. Simulation: Model Sim-6.2.
. Synthesis: Xilinx ISE 9.1i.
2. A FRAMEWORK FOR CORRECTION OF MULTI-BIT SOFT
ERRORS
Description:
This project is mainly developed for multi-bit error detection by using
simple error detection codes and correct the error using data redundancy in
the memory hierarchy. This project is mainly used to reduce the power
consumption. With the continuous decrease in the minimum feature size and
increase in the chip density due to technology scaling, on-chip L2 caches
are becoming increasingly susceptible to multi-bit soft errors. The
increase in multi-bit errors could lead to higher risk of data corruption
and potentially result in the crashing of application programs.
Traditionally, the L2 caches have been protected from soft errors using
techniques such as: 1) error detection/correction codes; 2) physical
interleaving of cache bit lines to convert multi-bit errors into single-bit
errors; and 3) cache scrubbing. In this paper, we investigate in detail the
multi-bit soft error rates in large L2 caches and propose a framework of
solutions for their correction based on the amount of redundancy present in
the memory hierarchy. We investigate several new techniques for reducing
multi-bit errors in large L2 caches, in which, the multi-bit errors are
detected using simple error detection codes and corrected using the data
redundancy in the memory hierarchy.

Responsibilities:
Analyzed the architecture area consumed by the architecture and power
consumption becomes less. And the multi-bit errors are detected using
simple error detection codes and corrected using the data redundancy.

and video. We put forward design and development of a novel, low complexity
processor in memory (PIM) architecture for image and video compression. By
integrative a Novel processing element with SRAM, bandwidth is improved and
latency is greatly reduced. Through this paper we present PIM design
techniques for reduced power, area, and complexity for rapid deployment and
reduced cost. A design methodology is presented and followed by an analysis
of the processing element performance and capabilities. The architecture
executes a discrete cosine and wavelet transforms achieving higher output
and area consumption is very less.

4. LOW POWER FLIP-FLOP USING CMOS DEEP SUBMICRON TECHNOLOGY;
Description:
1.This paper enumerates low power, high speed design of flip-flop having
less number of transistors and only one transistor being clocked by short
pulse train which is true single phase clocking (TSPC) flip-flop.
2. Compared to Conventional flip-flop, it has 5 Transistors and one
transistor clocked, thus has lesser size and lesser power consumption. It
can be used in various applications like digital VLSI clocking system,
buffers, registers, microprocessors etc.
The analysis for various flip flops and latches for power dissipation and
propagation delays at 0.13 m and 0.35 m technologies is carried out.
The leakage power increases as technology is scaled down.
3.The leakage power is reduced by using best technique among all run time
techniques viz- MTCMOS. Thereby comparison of different conventional flip-
flops, latches and TSPC flip-flop in terms of power consumption,
propagation delays and product of power dissipation and propagation delay
with SPICE simulation results is presented.

Regarding coding the functionality in non-SystemC C/C++: The SystemC
objects (sc_signal, sc_in, ...) are visible in the NCSIM GUI/Tcl user
interface, just like Verilog or VHDL objects. The native C/C++ objects
generally are not, but they can be made available to the GUI/Tcl interface
through a class ncsc_viewable (not supported by OSCI) that we added.

a new library and a logical mapping to it”
c.In the Library Name field you may specify a name or simply leave it as‘work’d.In the Library Physical Name field insert the path to the directory youcreated in 3, ex. /nmnt/work1/ece412/kkielty2/testSime.Repeat this procedure for a library that you will call ‘unisim’. (path may besomething like /nmnt/work1/ece412/kkielty2/unisim)6.Compile the unisim librariesa.First you will need to move them to your Linux machine so that ModelSimcan see them. The files you want to move over are in the local Windowshard drive in the lab.i.C:\Xilinx\vhdl\src\unisims1.unisim_SMODEL.vhd2.unisim_VCOMP.vhd3.unisim_
VITAL.vhd4.unisim_VPKG.vhdii.C:\Xilinx\verilog\src\ise\1.unisim_comp.v b.Next you will need to compile them. In ModelSim click
“Compile->compile”
c.Select ‘unisim’ as the libraryd.Using CTRL select the 4 files you just copied and hit “
Compile”
. This maygive you errors. If you see these then simply compiles the files in this order:VCOMP, VPKG, VITAL, SMODELi.You probably don’t need SMODEL – disk space may be an issueii.Also compile in the verilog file. This is vitally important!
