    A field programmable gate array (FPGA) utilizes an array of logic blocks, which can be configured by the user. The term “field programmable” implies that the device is programmable outside the factory where it is produced. The internal architecture of a FPGA device has three main parts, namely: The figure below illustrates the architecture of…

    Programmable array logic (PAL) architecture has a programmable AND array at the input and a fixed OR array at the output. The programmable AND array of a PAL device is similar to that of a programmable logic array (PLA) device. In other words, the number of programmable AND gates is usually smaller than the number…

    A programmable logic array (PLA) device has a programmable AND array at the input and a programmable OR array at the output, which makes it one of the most versatile programmable logic devices. The figure below, shows the internal architecture of a PLA device with four input lines, a programmable array of eight AND gates…
