Steering Logic Unit
The SLU operates as a three-channel serial digital data multiplexer. Information is shifted serially through the SLU during one word time. A 15-bit instruction command specifies which input or input combintions are to be “steered” to each of three data outputs. Inputs to the SLU may come from external digital sources (sensors, analog-to-digital converters), PDU, PMU, RAS, ROM. The output of the SLU typically goes to the PDU, PMU or RAS.
