Explanation: there are two types of pld, viz., devices with fixed architecture and devices with a flexible architecture. the main categories of plds are prom, pal and pla.
Explanation: pla refers to programmable logic array. it is a type of pld having programmable and and or gates.
Explanation: the inputs in the pld is given through and gate followed by inverting & non-inverting buffer. plds are programmable logic devices consisting of logic gates, flip-flops and registers connected together on a single chip. thus, it can be categorised into prom, pal and pla.
Explanation: outputs of the and gate in pld is known as output lines.
Explanation: programmable logic array is a type of fixed architecture logic devices with programmable and gates followed by programmable or gates. it is a kind of pld.
Explanation: since, pla is the combination of programmable and and or gates. so, it is used to implement complex combinational circuit.
Explanation: a pla is similar to a rom in concept except that it doesn’t provide full decoding to the variables and doesn’t generate all the minterms as in the rom. programmable logic array is a type of fixed architecture logic devices with programmable and gates followed by programmable or gates. it is a kind of pld.
Explanation: since pal consists of programmable and gates and fixed or gates and also circuitry working is less.
Explanation: the complex programmable logic device contains several pld blocks and a global interconnection matrix by which it communicates through several devices. it is also known as field- programmable gate arrays (fpgas).
Explanation: field-programmable gate arrays (fpgas) are reprogrammable silicon chips. in contrast to processors that you find in your pc, programming an fpga rewires the chip itself to implement your functionality rather than run a software application.
