  1. Complex Programmable Logic Device (CPLD) Architecture and Its Applications

  2. Complex Programmable Logic Device (CPLD) Architecture and Its Applications Introduction: • A CPLD (complex programmable logic device) chip includes several circuit blocks on a single chip with inside wiring resources to attach the circuit blocks. Each circuit block is comparable to a PLA or a PAL. These chips are inadequate to fairly modest sizes, normally supporting a mutual number of inputs and outputs of not more than 32. For designing of these circuits that need more inputs and outputs, either numerous PLAs/ PALs can be employed or else a more classy type of chip can be used called a CPLD http://www.elprocus.com/

  3. Complex Programmable Logic Device (CPLD) Architecture and Its Applications What is a Complex Programmable Logic Device? • The acronym of the CPLD is “Complex programmable logic devices. • it is a one kind of integrated circuit that application designers design to implement digital hardware like mobile phones.  • These can handle knowingly higher designs than SPLDs (simple programmable logic devices). • But It offer less logic than FPGAs (field programmable gate arrays). • CPLDs include numerous logic blocks. http://www.elprocus.com/

  4. Complex Programmable Logic Device (CPLD) Architecture and Its Applications What is a Complex Programmable Logic Device? • Each of the blocks includes 8-16 macrocells. • Every logic block executes a specific function. • All of the macrocells in a logic block are fully connected. • Depending upon the use, these blocks may or may not be connected to one another. • Most CPLDs have macrocells with a sum of logic function and an elective flip-flop. http://www.elprocus.com/

  5. Complex Programmable Logic Device (CPLD) Architecture and Its Applications What is a Complex Programmable Logic Device? • Depending on the chip, the combinatorial logic function supports from 4 to 16 product terms http://www.elprocus.com/

  6. Complex Programmable Logic Device (CPLD) Architecture and Its Applications What is a Complex Programmable Logic Device? • CPLDs also differ in terms of shift registers and logic gates. • Due to this reason, CPLDs with a huge number of logic gates may be used instead of FPGAs.  • Another CPLD specification signifies the number of product terms that a macrocell can accomplish. •  Product terms are the product of digital signals that execute a specific logic function. • CPLDs are available in several IC package forms and logic families.  http://www.elprocus.com/
