The methods and systems may provide a scalable round-robin arbiter tree that performs round-robin arbitration for a plurality of requests received from a set of requestors. The round-robin arbiter may stack a plurality of round-robin cells in stages where an output of a first stage of round-robin cells is an input to a next stage of round-robin cells. The round-robin arbiter may transform an arbitration state at each stage of the arbitration and propagate the arbitration state into the next stage for arbitration. The arbitration state from the final stage round-robin cell is fed back to the first stage of the round-robin cells and used in a subsequent arbitration round.

A medical device comprises a control system, processing modules, and a wire bundle connecting the control system to the processing modules, the wire bundle comprising control lines and data lines. Each processing module is coupled to a respective set of sensors arranged to interface with a biological tissue site, the sensors being configured to capture analog physiological signals generated from the biological tissue site. The control system is configured to generate a control signal on the control lines to initiate a data collection cycle by the processing modules. In response to the control signal, each processing module is configured to perform a respective data collection process which comprises (i) capturing and processing an analog physiological signal on each enabled sensor to generate a data sample for each analog physiological signal captured on each enabled sensor, and (ii) outputting data samples to the control system on the data lines.

A master request comprising a plurality of bits is received, each bit representing whether a host device of a plurality of host devices has issued a memory access request. The master request is divided into a plurality of slices, each respective slice containing a subset of the plurality of bits corresponding a subset of host devices. Based on the respective subsets of the plurality of bits, it is determined whether each respective slice contains at least one memory access request. A first round robin process then begins in which it is determined whether each respective slice contains a memory access request. If so, any memory access request contained in the respective slice are processed via a second round robin process before proceeding to process memory access requests of another slice. If the respective slice contains no memory access requests, processing skips to a next slice without processing the respective slice.
