What are the hardware components of an FPGA? 10

The structure inside the FPGA is made up of LUTs, IOs, Slice, etc.

Some external peripherals are equipped with crystal oscillators, power control circuits, JTAGs, etc.

FPGA stands for Field Programmable

The abbreviation of Gatearray, that is, Field Programmable Gate Array, is the product of further development on the basis of programmable devices such as PAL, GAL, CPLD, etc. It appears as a semi-customized circuit in the field of application-specific integrated circuits (ASIC), which not only solves the shortcomings of custom circuits, but also overcomes the shortcomings of the limited number of gates of the original programmable devices.

Power supply, configuration circuitry, user IO

FPGAs are generally used in embedded systems, especially as dedicated signal processors or IO for embedded systems, and are rarely used as separate CPUs

Ahh I won't. He came to cheat the points. Hee-hee.

Excuse me, what do you need?

It consists of six deferred preparation parts:

Programmable input-output unit (IO).

Basic programmable logic units (look-up tables and registers).

Complete clock management unit (DCM, PLL).

Embedded spring into the block RAM

Abundant wiring resources.

Embedded low-level functional units and embedded dedicated hardware modules (DSP, Serdes).

The main thing is logic circuit design.

Algorithm implementation, embedded system design.

For example, a system has its own bus system, including 8-bit data lines, 8-bit address lines, some control lines, etc. This kind of application requires a chip with many pins and can decode quickly, and this is the strength of FPGA CPLD. And because of its parallel characteristics, it can achieve ideal results when reading and writing RAM or doing a large number of IO processing (such as an IO card with a 10-channel input).

At the same time, according to the current trend, when the NIOS system (equivalent to ARM or microcontroller) is becoming more and more mature and faster, we can incorporate a complex system into FPGA, that is, only one FPGA is used to achieve most of the functions, the so-called SOPC. This can greatly save PCB area and cost.

And with a more professional one:

Logic control, signal processing, image processing, etc.

The advantages of FPGAs are that they are fast, fast, and can be processed in parallel.

It is widely used in the fields of national defense, aerospace, industry, medical and other fields, and is also widely used in the process of scientific research and development because of its flexibility.

1.The realm of logical interfaces, i.e., the traditional realm.

2.algorithm, which is implemented with HDL.

3.On-chip programmable system, control.
