FPGA - Field Programmable Gate Array A field-programmable gate array is a semiconductor device containing programmable logic components called "logic block…s", and programmable interconnects. ( Full Answer )
FPGA Spartan is more efficient than the microcontroller. It is usedto perform operations that cannot be properly done bymicrocontrollers; operations like high parallel or low …latencyoperation. ( Full Answer )
FPGA have less density. Moreover , it is gaining more market share due to it's reasonable NRE (Non Recurrent Engineering) cost and fast time to implement and manufacture in t…he market. ( Full Answer )
It depends on what you need. Basically there are two main parameters: 1. no of IOs 2. complexity of logic you want to synthesize there are other considerations of spee…d, types of IO signalling, development tools etc. And of course cost, that includes cost of the device itself as well as cost of development and manufacturing. I am saying this because most higher end FPGAs are fine-pitch BGAs with hundreds of balls that need multilayer boards and obviously an application that deserves it. If you are a newbie you can start with simpler Xilinx Spartan 3 series devices which have very low cost development boards available and if you intend to make a product they can be easily integrated with regular electronics assembly process.

FPGAs and CPLDs are both programmable logic. However the main difference lies in the architecture of the chips..
CPLDs have several programmable PLDs which are interconne…cted via a programmable connections at the global interconnection matrix..
FPGAs on the other hand have individual logic blocks - each block can be programmed to implement a logic function such as AND, OR, NOT etc. These blocks are then connected via programmable switches to implement complete logic functions..
Compare the FPGA way of programming individual AND, OR, NOT logic functions and then putting them together to implement a complete logic function, to the CPLD way of programming several complete logic functions at once on inividual PLDs and then bringing these PLDs together via programmable connections..

PSoC devices are more user friendly than FPGA, But PSoC are limited in functionalities comparable to FPGA as FPGA can have any digital block but PSoC has some limited Digital …blocks pre defined in the flash memory. FPGA requires VHDL and verilog to be programmed where as PSoC can be easily programmed just like any other ordinary microcontroller. PSoC surpassed the FPGA as PSoC now-a-days are containing almost all blocks that are usually needed and thus makes them more flexible than FPGA chips. ( Full Answer )
A microcontroller is a computer with lots of control over input and output, which can do computations, loops, timing, conditional branching, and all the other things a compute…r can do, UNDER PROGRAM CONTROL. FPGA, Field Programmable Gate Array, is just that , an array of gates that you can configure any way you want. But it is not a computer, just a bunch of gates. ( Full Answer )
Now FPGAs are having builtin processor like PPC and more either inhardcore or softcore. Main difference between processor and FPGA isexecution Processor is sequencial executio…n but FPGAs areconcurrent so speed of FPGA is much higher than a high speedprocessor. ( Full Answer )
There are many boards available in India, check for Xilinxdevelopment boards and digilent's. I have a papilio one board thatcosts rs 3000 which is great for beginners. I have …also bought acouple of add-on board for this board. ( Full Answer )
FPGAs come in a wide range of prices, from under $10 (in ones) for a small, slow FPGA with around 50,000 gates to well over $1000 (in ones) for a large, fast FPGA with over 1,…000,000 gates. ( Full Answer )
1. Both ASIC and FPGA are IC's 2. However ASIC Application Specific IC the functionality is Fixed. 3. In SAME FPGA Field Programmable Gate Arrays various different types of A…pplication can be programmed. And that too in the Field. ( Full Answer )
There are huge differences between the two even though they might do the very exact same job in some projects but the main difference is that in FPGAs we use HDL (hardware des…cription language) on the same piece of hardware while on Embedded Systems you use a programming language(e.g. C) and the hardware you need for your project ( Full Answer )
FPGA is a programmable device you have to interface this with adisplay device and input device to get image. Then you can write alogic to process the image for the very partic…ular device. This islittle tough job so take support from DSP for more complicatedformats. ( Full Answer )
Verilog HDL / VHDL is a hardware description language used to implement a hardware on a computer virtually. It means that we can append all the attributes of a hardware to a c…omputer program and verify as to how it works. But there may be differences in its behavior when it is actually implemented physically. For example, there may be an unexpected time delay. So, it is required to verify the design physically. Hence, we dump this Verilog / VHDL code into an FPGA / CPLD and verify the design physically. In other words, Verilog HDL / VHDL program is used to verify the design on a computer where as FPGA / CPLD implementation is used to verify the design on an IC. ( Full Answer )
The major difference is that, a DSP is a chip which can be programmed based on our requirement, whereas an FPGA can be programmed to design a chip for our own purpose. FPGA ca…n also be reprogrammed based on the changes in our application. ( Full Answer )
fpga and plc are two completely different things. FPGA( field programmable gate arrays) are building blocks of electronic sysytem where as plc are systems. Comparing these two… is like comparing engine with car. ( Full Answer )
Any signal would have four states high indicated by 1, low indicated by 0, high impedance indicated by Z and unknown indicated by X. An unknown signal often occurs when you… have not connected the pin to anything or you are trying to take output from the pin while it is not really giving the proper output ( Full Answer )
