An array of programmable logic blocks and a reconfigurable hierarchy are the two primary technologies in the configuration of an FPGA module. Interconnects allow these blocks to be configured in various ways after fabrication. Compared to other chips, FPGA modules modules provide a significant combination of programming and performance. FPGA makes it possible to achieve low latency for real-time inference requests. Asynchronous requests are not required. Batch submission can cause latency because more data needs to be processed. Neural processing unit implementations do not require batch submission.
Reconfiguration of FPGA for different types of machine learning models is easier. This flexibility makes it easier to accelerate applications based on the most optimal numerical accuracy and the memory model being used. Because FPGA is reconfigurable, you can stay up to date with the requirements of rapidly changing AI algorithms.
FPGA Definition and configuration
The Field Programmable Gate Array can be summarized as a computer architecture that combines the flexibility and continuous change of the software with the high performance of the board. Being reprogrammed, the user can use it in a project and reprogram it so that it runs another project that is not dependent on the previous one without interfering with the project to be developed. You can do it by reprogramming its functions in a simple way using Hardware Description Language. Its cost in relation to the ASIC, and the total time spent is lower in relation to a project made using the ASIC technology. Always keep in mind that any error in ASIC module will cost the whole process, as it must be restarted from the start. FPGA would take a few hours/minutes and cost zero.
Primary difference with other modules
Its main difference between commonly known microprocessors is their ability to change their data paths and control flows, enabling and disabling only certain project modules through its configurations. The FPGA is an arrangement of configurable logic blocks and logic cells that are arranged on a single board and in technical definitions. It is mainly composed of three component modules: input and output blocks, configurable logic blocks and interconnects switches.
Input and Output Blocks
They are the modules in which the input data are interconnected as the results of the configurable logic blocks. We can assimilate its definition with the functionalities of a keyboard buffer, in which it transmits data coming from the keyboard, besides sending, could also receive data
Configurable Logical Blocks
They are manufactured in a two-dimensional way creating small function modules of circuits. They are arranged with flip-flop sets with combinational logic. More generally, they behave like a truth table in which it is possible to produce a given output.
These are the tracks that form the connection between the input and output blocks with the configurable logic blocks. Static memory cells are configured by the board’s compiler, determining the logic functions that will be used and the internal connections. Containing a number of thousands of identical logical units, these units can be independently configured and connected from the conductor line array and switches. The FPGA is an array of logical units with a matrix of interconnections that can be configured by the user.
