FPGA stands for Field Programmable Gate Arrays. These were once simple blocks of gates that can be arranged by the user to employ the logic that they want. In contrast, a microprocessor is a streamlined CPU or Central Processing Unit that implements a program that encompasses a specific set of instructions. The main difference between the two is intricacy.
Microprocessors tend to be more complicated than FPGA’s. Microprocessors already encompass a fixed set of instructions, which the programmers need to learn to establish the appropriate working program. Each of these instructions has its corresponding block that is already hardwired into the microprocessor. An FPGA does not have any hardwired logic blocks because it would defeat the programmable field aspect. An FPGA is set out like a net with each junction, including a switch the user can make or break.
This switch affects how the logic of each block is determined. Programming an FPGA involves learning HDL (Hard Description Language). The microprocessor can handle the common tasks while custom FPGA blocks give you the capacity to integrate unique blocks, and you can also take an FPGA and get it to work as a single logic gate.
Some simple blocks of gates that the user can configure to implement the logic he or she desires is the FPGA, which fully means Field Programmable Gate Arrays. On the other hand, a microprocessor just a form of CPU or Central Processing Unit that is made in a simplified manner. A major function it carries out is to execute a program containing a certain set of instructions. Due to the various processes that have been implemented in the microprocessor, it makes it a bit more complex than the FPGA, and this forms the major difference between them. The issue about microprocessors is that you have to learn some sets of instructions with some hardwired logic blocks. This might seem a bit of a task for the user to do. These hardwired logic blocks are not present in the FPGA. You can actually make use of one for the other if you have good knowledge about them.
The microprocessor is considered to be the one that is in charge of handling different tasks. If you would like to incorporate unique blocks, that is the time when you would need to use FPGA blocks. If you would like to know the difference in their complexity, the microprocessor is considered to be more complex.
Microprocessors will come with fixed instructions. FPGAs, on the other hand, may come with different instructions to ensure that it will be able to work properly. Take note that FPGAs and microprocessors often have to work well together to ensure that they are placed in just one package. The more that they work together, the better that they can work properly.
FPGA, which means Field Programmable Gate Arrays used to refer to simple blocks of gates that a user can use to implement his or her desirable logic by configuration. On the other hand, a microprocessor refers to a simplified Central Processing Unit (CPU) that can be used to carry out a program with defined inputted data or instructions.
The microprocessor has several processes implemented in it, which makes it seem more complex than FPGAs. Microprocessors have a set of instructions that are fixed already, while FPGAs do not. All the programmer needs to do is to learn the set of instructions and create his or her desirable program.
Each of the instructions already has its own equivalent block that is hardwired into the processor. This is not so for FPGA, where you will need to learn Hardware Description Language (HDL) in order to make or break a switch that is contained in each junction of the FPGA layout.
