Shift register lookup table

Shift register lookup table.

A shift register lookup table, also shift register LUT or SRL, refers to a component in digital circuitry. It is essentially a shift register of variable length. The length of SRL is set by driving address pins high or low and can be changed dynamically, if necessary.[1]

The SRL component is used in FPGA devices. The SRL can be used as a programmable delay element.
