Efficient controllers and implementations for elastic buffers

摘要

Systems and methods relating to an elastic buffer for dynamically adjusting depth of a data-path implemented on an integrated circuit device. The device includes a first flip-flop, a second flip-flop, a multiplexer, and a controller. The first and second flip-flops are arranged in a cascade configuration with the multiplexer interposed therebetween. In certain embodiments, the multiplexer is capable of selecting between input received upstream and the output of the first flip-flop. The controller utilizes control logic to drive the first and second flip-flops and the multiplexer. The first and second flip-flops, and the multiplexer may represent an elastic buffer subunit corresponding to a single bit within a larger elastic buffer, in which a plurality of elastic buffer subunits are cascaded to form the elastic buffer along with a single shared controller.
