Event-driven readout system with non-priority arbitration for multichannel data sources

A method of non-priority arbitration of a plurality of channels using an event-driven readout management system, the method comprising:

• determining, using an arbitration tree circuit, to which of the plurality of channels to grant access to a common signal transfer resource shared by the plurality of channels, the determination based on a readout access request provided by at least one of the plurality of channels;
• excluding, using the arbitration tree circuit, simultaneous occurrence of multiple readout access requests from the determination;
• receiving and storing the readout access requests in the arbitration tree circuit until access is granted to the common signal transfer resource by the arbitration tree circuit;
• terminating, using the arbitration tree circuit, a prior readout transaction and commencing a subsequent readout transaction in response to a single edge of a clock signal;
• providing an acknowledge token to the arbitration tree circuit, the arbitration tree circuit using the acknowledge token to grant access to the common signal transfer resource, a state of the clock signal representing the acknowledge token;
• generating, using an in-channel logic circuit, the readout access request and receiving the acknowledge token, the in-channel logic circuit operatively coupled to the arbitration tree circuit;
• terminating, using the in-channel logic circuit, the prior readout transaction and commencing the subsequent readout transaction in response to receiving the acknowledge token;
• and
• converting, using an output periphery circuit, information received from the plurality of channels into an output format on the common signal transfer resource.

A non-transitory computer-readable medium comprising instructions that, when executed by a processing device, perform operations comprising:

• determining, using an arbitration tree circuit, to which of the plurality of channels to grant access to a common signal transfer resource shared by the plurality of channels, the determination based on a readout access request provided by at least one of the plurality of channels;
• excluding, using the arbitration tree circuit, simultaneous occurrence of multiple readout access requests from the determination;
• receiving and storing the readout access requests in the arbitration tree circuit until access is granted to the common signal transfer resource by the arbitration tree circuit;
• terminating, using the arbitration tree circuit, a prior readout transaction and commencing a subsequent readout transaction in response to a single edge of a clock signal;
• providing an acknowledge token to the arbitration tree circuit, the arbitration tree circuit using the acknowledge token to grant access to the common signal transfer resource, a state of the clock signal representing the acknowledge token;
• generating, using an in-channel logic circuit, the readout access request and receiving the acknowledge token, the in-channel logic circuit operatively coupled to the arbitration tree circuit;
• terminating, using the in-channel logic circuit, the prior readout transaction and commencing the subsequent readout transaction in response to receiving the acknowledge token;
• and
• converting, using an output periphery circuit, information received from the plurality of channels into an output format on the common signal transfer resource.
