FPGA offers users a wide range of applications by enabling manufacturers to implement systems that can be updated when necessary.
FREMONT, CA: FPGAs consist of many configurable logic blocks, which can be programmed based on what functions the designer requires them to perform. An FPGA contains a programmable interconnect matrix along with the logic blocks, allowing the designer to configure the FPGA's internal wiring. The confirmable logic blocks and the interconnect matrix make the FPGA a flexible and powerful technology. FPGA offers numerous advantages, making it an attractive option in various applications.
Performance is the primary advantage of FPGA. A general CPU cannot perform parallel processing, giving FPGAs control as they can perform processing and calculations in parallel at a faster rate. A carefully designed FPGA can implement any function quicker than a CPU, which is sequentially running software code. FPGAs have additional gates and wiring, making them flexible and programmable. This overhead comes at a cost, making FPGAs run slower than ASICs.
One of the most significant advantages of FPGAs is their re-programmability. Even after designing and implementing the circuit, FPGAs can still be modified, updated, and completely changed in functionality to perform a completely different task than before. Reprogrammability reduces the effort and cost required for long-term chip maintenance. It eliminates the need to invest in replacing or redesigning new hardware when the old one becomes obsolete. One can simply update its code and programme it in the field with new functionalities.
Since FPGAs are often reprogrammable, they are extremely cost-effective in the long run, even though they may pose higher unit costs. This is a significant advantage as it reduces the need to cover recurring bug-related costs that make individuals pay if they opt for an ASIC. ASICs also have huge non-recurring expenses skipped altogether. FPGAs, however, do not require the use of any expensive tools to design or configure FPGA chips.
Parallel Task Performance
Chips sequentially performing data processing are not used in time-critical applications. FPGAs can be designed to integrate multiple blocks processing data in parallel. This offers greater scalability as compared to other processors like ASICs and MCUs and time-critical data processing.
As already discussed, one of the key advantages of FPGAs is re-programmability and reusability. These functions make them the perfect choice for prototyping purposes, especially for ASIC validation purposes. Before reviewing an ASIC, it is important to determine if the ASIC design is functioning and successfully achieves the purpose it has been designed for. ASICs are difficult and expensive to manufacture, requiring a considerable time, investment and money to redesign the ASIC when the chip needs modification.
FPGs’ re-programmability feature allows users to perform test runs by manipulating the programming and determining the ideal configuration on one chip only. After completing prototyping and determining the optimal solution, FPGAs can be translated into a permanent ASIC and deployed for use.
