In Chapter 6, real life problems will be handled using Digital System Design based on VHDL. In Introduction we give som of the recent advances in FPGA architecture and we implement BCD-to-Seven Segment Decoder to drive a Seven-Segment Display.

DSD_Chapter 6_Mighty Spartans in Action_Introduction.

Spartan2 and Spartan3 is the name assigned to FPGA developed by the company Xilinx. This name has come from the name Sparta of a City State in Greece in 1000BC. At that time there were two City States Sparta and Athens. Sparta had Oligarchy form of government whereas Athens had Democratic form of government.

Sparta was unique in the ancient times for its social system and constitution, which completely focused on military training and excellence and it dominated Greece peninsula up to 300BC. Subsequently by 100BC it was conquered by Romans. Its inhabitants were classified as Spartan citizens, who enjoyed full rights, non-Spartan free men raised as Spartans, freedmen and state-owned serfs (enslaved non-Spartan local population). Spartans underwent rigorous military training and education regimen, and Spartan soldiers were widely considered to be among the best in battle. Spartan women enjoyed considerably more rights and equality to men than elsewhere in the classical world. Spartans remained a city state which fascinated the people of all cultures and of all times. Thus we have FPGA named Spartan2 and Spartna3.

The following excerpts have been taken from EE Times:

“Since their introduction in the mid-80s, FPGAs have managed to wedge themselves as a fixture into the electronics design landscape. Sitting somewhere between off-the-shelf (OTS) logic, ASICs, OTS processors, and ASSPs, they continue to enjoy growth predictions beyond those of the rest of the semiconductor industry”.

An application specific standard product or ASSP is an Integrated Circuit that implements a specific function that appeals to a wide market. As opposed to ASIC that combines a collection of functions and designed by or for one customer, ASSPs are available as off-the-shelf components. ASSPs are used in all industries, from automotive to communications.

Examples of ASSPs are integrated circuits that perform video and/or audio encoding and/or decoding.

“The latest high-end devices: 28 nm silicon, more metallization layers than ever before, and equivalent gate counts that would see any self-respecting ASIC proud. Historically, these leading edge devices have found the greatest use in networking, DSP, and military/aerospace applications. These are domains where raw performance requirements exceed those available from software-only solutions, but whose volumes cannot always justify the costs of custom silicon development. These devices are more than capable of hosting a full 32-bit soft processor core running at around 50 to 100 MHz as well as several soft peripherals such as a video display driver, UART, Ethernet controller, or IDE controller”.

“Field-programmable gate arrays (FPGAs) have become incredibly capable with respect to handling large amounts of logic, memory, digital-signal-processor (DSP), fast I/O, and a plethora of other intellectual property (IP)”.“At 28-nm, FPGAs deliver the equivalent of a 20- to 30-million gate application-specific integrated circuit (ASIC). At this size, FPGA design tools, which have traditionally been used by just one or two engineers on a project, begin to break down. It is no longer practical for a single engineer, or even a very small design team, to design and verify these devices in a reasonable amount of time”.“Due to recent technological developments, high-performance floating-point signal processing can, for the first time, be easily achieved using FPGAs. To date, virtually all FPGA-based signal processing has been implemented using fixed-point operations. This white paper describes how floating-point technology on FPGAs is not only practical now, but that processing rates of one trillion floating-point operations per second (teraFLOPS) are feasible—and on a single FPGA die. Medical imaging equipment is taking on an increasingly critical role in healthcare as the industry strives to lower patient costs and achieve earlier disease prediction using noninvasive means. To provide the functionality needed to meet these industry goals, equipment developers are turning to programmable logic devices such as Altera's FPGAs”.

Maira Reply
There are lots of products of nano chemistry... Like nano coatings.....carbon fiber.. And lots of others..
Even nanotechnology is pretty much all about chemistry... Its the chemistry on quantum or atomic level
no nanotechnology is also a part of physics and maths it requires angle formulas and some pressure regarding concepts

what about nanotechnology for water purification
RAW Reply
please someone correct me if I'm wrong but I think one can use nanoparticles, specially silver nanoparticles for water treatment.
yes that's correct
I think
Nasa has use it in the 60's, copper as water purification in the moon travel.
