What is FPGA?
What is FPGA?
FPGA stands for Field Programmable Gate Array,
which means a chip that can be programmed on-site.
FPGA is essentially a chip,
not a tool or a device, and certainly not software.
It is a type of chip.
FPGA can change the internal circuit structure of the chip through programming,
to meet the application needs of different hardware products.
Programming an FPGA is fundamentally different from software programming.
Programming a CPU or microcontroller often involves changing the configuration of the registers on it,
but does not change the logical functions of that chip.
What is the essential difference between FPGA programming and software programming?
For example, you cannot program a graphics processing chip to become a communication chip through software programming,
but FPGA can.
The programmability of FPGA is called hardware programmability.
This allows FPGA to be programmed from a logic gate array,
thus enabling FPGA to change at the logical circuit level.
Why is FPGA called ‘Field Programmable’?
FPGA can be programmed in the field,
without needing to remove the chip,
or send it back to the manufacturer for programming.
It can be programmed in real-time, either remotely or locally.
What advantages does FPGA have?
FPGA can implement any circuit combination,
we can think of FPGA as a collection of Legos,
which can be assembled into very simple models,
or combined into very complex models as needed.
This gives FPGA a high degree of flexibility.
What advantages does FPGA have?
Because FPGA implements functions through logical circuits,
its computation is very strong,
and it has very low power consumption,
therefore many people call it the ‘King of Chips’.
It is widely used in many industries.
