A processor comprises a plurality of processor units arranged to operate concurrently and in cooperation with one another, and control logic configured to direct the operation of the processor units. At least a given one of the processor units comprises a memory, an arithmetic engine and a switch fabric. The switch fabric provides controllable connectivity between the memory, the arithmetic engine and input and output ports of the given processor unit, and has control inputs driven by corresponding outputs of the control logic. In an illustrative embodiment, the processor units may be configured to perform computations associated with a key equation solver in a Reed-Solomon (RS) decoder or other type of forward error correction (FEC) decoder.

Tuning an optical network unit (ONU) to an appropriate communication wavelength may be performed by initiating an activation procedure responsive to receiving a wavelength configuration message, and identifying an instruction in the wavelength configuration message to modify a present wavelength used by the network unit to a different wavelength. The process may also provide assigning an optical network unit identifier (ONU-ID) to the network unit, modifying the present wavelength to the different wavelength, and transmitting subsequent data messages from the network unit at the different wavelength.
