Final answer:
Described the stages A to E of signal propagation in the AXI4 Stream HDMI input peripheral, focusing on the conversion from TMDS to AXI4-Stream.
Step-by-step explanation:
The AXI4 Stream HDMI input peripheral suggests an engineering focus on the processes involved in digital signal transmission and conversion. The component in question likely interfaces with high-definition multimedia interfaces (HDMI) and processes data conforming to the AXI4-Stream protocol. As requested by the student, we'll construct a representation of the key elements of the signal propagation within such a peripheral.
Stages of Signaling Process
Stage A to B: This represents the initial reception of TMDS (Transition Minimized Differential Signaling) data. The peripheral decodes the TMDS signaling into discrete data channels. This is crucial to prepare the data for the next stage of processing.
Stage B to C: At this juncture, the decoded data is typically serialized, where parallel data may be converted into a serial stream.
Stage C to D: During this stage, data serialization is followed by necessary signal conditioning which might involve cleaning up the signal from noise and ensuring it meets the protocol timing specifications.
Stage D to E: Here, the conditioned serial data is packed into an AXI4-Stream compatible format. The data is now ready to be handled by the AXI protocol.
Stage E to A: The cycle may conclude with the signal processing logic carrying data back to Stage A, suggesting a feedback mechanism or the beginning of a new data transfer cycle.
The explanation of these stages and the conversion of TMDS to AXI4-Stream protocol signals are vital for understanding the operation of the HDMI input peripheral within a digital system's architecture.
