Abstract: A method and apparatus for embedding a microprocessor in a programmable logic device (PLD), where the microprocessor has a logic unit that can operate in two modes. A first mode is a general purpose mode running at least one general purpose process related to the PLD, and a second mode is a fixed function mode emulating a fixed function for use by logic configured into a fabric of the PLD (fabric). A memory unit is coupled to the logic unit and to the fabric, and the fabric is operable for transferring signals with the logic unit in relation to the fixed function.
