Answer: A complex programmable logic device (CPLD) is a programmable logic device with complexity between that of PALs and FPGAs, and architectural features of both. The main building block of the CPLD is a macrocell, which contains logic implementing disjunctive normal form expressions and more specialized logic operations.
Answer: 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.
Answer: Macrocells are the main building blocks of a CPLD, which contain complex logic operations and logic for implementing disjunctive normal form expressions. ... Macrocells can also be defined as functional blocks responsible for performing sequential or combinatorial logic.
Answer: CPLD is ROM base. FPGAs are \u201cfine-grain\u201d devices. That means that they contain a lot (up to 100000) of tiny blocks of logic with flip-flops. CPLDs are \u201ccoarse-grain\u201d devices. They contain relatively few (a few 100's max) large blocks of logic with flip-flops.
