When it comes to understanding the difference between FPGA vs CPLD, it is important to know that they are both integrated circuits. FPGA stands for Field Programmable Gate Array and CPLD stands for Complex Programmable Logic Device.
They are both used to create custom hardware designs, but there are some key differences between the two. FPGAs are more suited for larger projects with more complex designs, while CPLDs are better for smaller projects with less complex designs.
So, which is better? It really depends on the project you are working on. Keep reading to learn more about the key differences between FPGA vs CPLD!
What is FPGA?
FPGA stands for Field Programmable Gate Array, which is an integrated circuit that can be programmed to do a specific task. It is similar to an ASIC in that they both use the same “processing engine”.
What sets FPGAs apart from ASICs are their flexibility and ability to change in order to do new tasks.
As it is an integrated circuit (IC), it that can be configured by a customer or designer after manufacturing to perform certain functions.
FPGAs are used in an array of applications due to their flexibility and performance. They are widely used in high-performance computing systems, data centers, embedded systems and video processing systems.
What is CPLD?
CPLD stands for Complex Programmable Logic Device. It is a chip of silicon that can be programmed to perform certain functions like a computer chip. The CPLD has no RAM, and can only store one program which is coded on it by the programmer.
As Complex Programmable Logic Device (CPLD) is a logic chip that can be programmed to perform complex combinational functions.
CPLDs are often used to speed up the design process of digital circuits and they are now becoming more common in modern electronics.
There are two types of CPLDs: the programmable variety, which is designed for customization, and semi-customized chips, which offer a smaller amount of flexibility and have pre-programmed functions.
FPGA vs. CPLD – Which One is Right for Your Design
FPGA and CPLD are two digital logic integrated circuits. They both have many similarities, but they also have a few differences.
Both FPGA and CPLD are programmable, but FPGA is also reconfigurable. That is to say, you can change the way it’s partitioned through configuration data. This means that certain operations will only be done in that partition – such as when the data from one partition needs to be moved to another partition for processing.
CPLDs can only be configured on power-up once and cannot be reconfigured afterwards outside of unsoldering and replacing them with a new chip.
Conclusion:
In conclusion, there are a few key differences between FPGAs and CPLDs. FPGAs are better suited for applications that require high levels of flexibility and customization, while CPLDs are better suited for applications that require low levels of flexibility and customization. Ultimately, the best choice for a particular application depends on the specific requirements of that application.
