What is the difference between a CPLD and an FPGA?

FPGA contains up to 100,000 of tiny logic blocks while CPLD contains only a few blocks of logic that reaches up to a few thousands. FPGAs are made up of tiny logic blocks while CPLDs are made of larger blocks. 5. FPGA is a RAM-based digital logic chip while CPLD is EEPROM-based.

Why is CPLD used?

Applications of CPLD CPLD is used for loading the configuration data of a field programmable gate array from non-volatile memory. CPLDs are frequently used many applications like in cost sensitive, battery operated portable devices due to its low size and usage of low power.

What is the use of CPLD?

Applications of CPLD CPLDs can be used as bootloaders for FPGAs and other programmable systems. CPLDs are often used as address decoders and custom state machines in digital systems. Due to their small size and low power consumption, CPLDs are ideal for use in portable and handheld digital devices.

What is CPLD in VLSI?

Complex Programmable Logic Device (CPLD) is programmable logic device and can be programmed by using VHDL. CPLDs are based on EPROM or EEPROM technology. CPLDs are having extended density than the SPLDs. The concept of CPLDs is to have a few macrocells on a single chip with simple logic paths.

Which of the PLDS is costliest and complex?

In PLA the connections to both AND and OR arrays are programmable. PLA is considered more expensive and complex as compared to the PAL. The two different manufacturing techniques can be used for PLA to increase the ease of programming.

What is difference between PAL and PLD?

The programmable logic device or PLD is one kind of chip used to implement the logic circuit. It includes a set of logic circuit elements that can be modified in several ways….Difference between PAL and PLA.

What is CPLD in Verilog?

CPLD: Complex Programmable Logic Device, design independent integrated circuit. Advantages: users can design more complicated circuit systems in a more time and cost efficient manner. Verilog: standardized and vendor independent hardware description language used to write code for circuit synthesis and simulation.
