A programmable logic array (PLA) is a kind of programmable logic device used to implement combinational logic circuits. The PLA has a set of programmable AND gate planes, which link to a set of programmable OR gate planes, which can then be conditionally complemented to produce an output. It has 2ᴺ AND Gates for N input variables, and for M outputs from PLA, there should be M OR Gates, each with programmable inputs from all of the AND gates. This layout allows for many logic functions to be synthesized in the sum of products canonical forms.

Control system for a vibroseis

This application discloses a control system for a controllable vibration source, belonging to the field of controllable vibration sources. This control system achieves precise control of the controllable vibration source through a host computer and a system-on-a-chip (SoC) integrating a processor and a programmable logic array (PLA). The host computer transmits configuration information to the PCA, where the processor generates a reference scan signal based on the configuration information. The processor then controls the vibrator of the controllable vibration source to perform vibration operations based on the reference scan signal. Furthermore, to ensure that the vibration signal generated by the vibrator meets requirements, a control algorithm can be executed through the PCA to generate control signals. These control signals can then be used to precisely adjust the vibration signal generated by the vibrator, thus achieving precise control of the controllable vibration source.
