How can a design inform other modules that the sensor data is used in a communication process?
This lecture will cope with this question.
In some cases, it is better that the data generator keeps the data valid until it ensures that the
consumer receives the data.
In this case, it can wait to receive an acknowledged signal from the consumer.
The AP underscored export interface at such a signal to a port it can be applied to the input or output
ports.
This figure shows the timing of waveforms for the acknowledged signals attached to the input and output
ports, when a design reads the data on an input port with an associated acknowledged signal, it activates
the signal to inform the sender of the data consumption.
When the design sends out the data it keeps that is stable until it receives the acknowledged signal,
then it can release the value on the output port or assign any value.
In summary, for input arguments, the design generates an output acknowledge that is active, high
in the cycle when the input is read.
For output arguments, why does such US implements an input acknowledged signal to confirm the output
was already?
The AP underscore Wieldy and AP underscore AKH provide one way handshaking between two modules how can
we provide Two-Way handshaking between two hardware modules?
Invite the specialists.
The next lecture will cope with this question.
These are our takeaway messages in a multi cycle design, the data consumer module should sometimes
inform the sender of sampling to date.
Therefore, there should be a mechanism to acknowledge the received data.
The AP underscored export interface invited socialist and unacknowledged signal to a data port.
Now, the police question considered the following other design, synthesize the code and performed
RTL archaeological simulation and check the underscore X signaling in the waveform window.
