Difference Between CPLD and FPGA

The primary differences between CPLD and FPGA are architectural. A CPLD has a restrictive structure which results in less flexibility. The FPGA architecture is dominated by interconnects, which makes them not only far more flexible but also far more complex to design.

What is CPLD used for?

CPLD is used for loading the configuration data of a field programmable gate array from non-volatile memory. CPLDs are frequently used many applications like in cost sensitive, battery operated portable devices due to its low size and usage of low power.

What does CPLD stand for?

A complex programmable logic device (CPLD) is a programmable logic device with complexity between that of PALs and FPGAs, and architectural features of both. The main building block of the CPLD is a macrocell, which contains logic implementing disjunctive normal form expressions and more specialized logic operations.

Is FPGA a PLD?

The latest Electronics Weekly product news on FPGA (field-programmable gate array) and PLD (programmable logic device) devices to be (re)configured by a user after manufacturing.

What is the difference between FPGA and ASIC?

ASIC means Application Specific Integrated Circuit. It is a device that is created for a specific purpose or functionality. The difference in case of ASIC is that the resultant circuit is permanently drawn into silicon whereas in FPGA the circuit is made by connecting a number of configurable blocks. ...

Is FPGA a microprocessor?

A Field Programmable Gate Array or FPGA is an integrated circuit that could contain millions of logic gates that can be electrically configured to perform a certain task. ... Microprocessor vs FPGA: A microprocessor is a simplified CPU or Central Processing Unit.

Why FPGA is faster than CPU?

So, Why can an FPGA be faster than an CPU? In essence it's because the FPGA uses far fewer abstractions than a CPU, which means the designer works closer to the silicon. ... FPGAs have fewer abstractions and so they can be faster and more power efficient but difficult to program for.

What FPGA means?

It is an acronym for field programmable gate array.

Which type of device FPGA are?

Which type of device FPGA are? Explanation: Field-Programmable Gate Arrays (FPGAs) are reprogrammable silicon chips. In contrast to processors that you find in your PC, programming an FPGA rewires the chip itself to implement your functionality rather than run a software application. Thus, FPGAs are PLD devices.

Why Antifuses are implemented in a PLD?

13. Why antifuses are implemented in a PLD? Explanation: Programmable Logic Devices is a collection of a large number of gates, flip-flops, registers that are interconnected on the chip. Programming is accomplished by using antifuses in a PLD and it is fabricated at the cross points of the gates.

Does FPGA have memory?

The FPGA fabric includes embedded memory elements that can be used as random-access memory (RAM), read-only memory (ROM), or shift registers. These elements are block RAMs (BRAMs), LUTs, and shift registers. ... The data of the ROM is written as part of the FPGA configuration and cannot be modified in any way.

Where is FPGA used?

FPGAs are particularly useful for prototyping application-specific integrated circuits (ASICs) or processors. An FPGA can be reprogrammed until the ASIC or processor design is final and bug-free and the actual manufacturing of the final ASIC begins. Intel itself uses FPGAs to prototype new chips.

How many times can you reprogram an FPGA?

Altera guarantees you can reprogram windowed EPROM-based devices at least 25 times. Altera does not specify the number of times you can reprogram or reconfigure FPGA devices because these devices are SRAM-based. An SRAM-based device can be reconfigured as often as a design requires; there is no specific limit.
