Abstract
A vector-domain engine configured to perform conditional operations on an operand vector in a programmable logic device is disclosed. The vector-domain engine may receive an instruction from and transmit an output vector to a programmable-logic-device domain. The output vector may be a first or second output vector depending on whether a comparison unit in the engine determines that a bit-field of the operand vector matches a designated pattern. The first output vector may be the operand vector modified by a function unit, and the second output vector may be the operand vector unmodified. A shifter may be employed to shift the bit-field to a desired position in the operand vector. The operand vector may comprise a pattern-defining portion and a data portion. The engine may also be configured to test a predetermined number of sequential operand vectors for the presence of the pattern.
