Signal processing apparatus for generating a plurality of output samples using combiner logic based on a hiearchical tree structure

A method of providing a plurality of output samples based on a plurality of input samples, the method comprising:

• generating sets of processing core output samples using a plurality of processing cores, wherein said generating is based on sets of the plurality of input samples and associated processing times for the sets of the plurality of input samples,
• processing the sets of processing core output samples by a sample combiner logic unit comprising a hierarchical tree structure comprising a plurality of hierarchical levels of combiner nodes, the processing comprising:
• combining output samples of a higher hierarchical level to generate first combined output samples;
• and
• combining at least the first combined output samples to generate second combined output samples, wherein the second combined output samples include more samples than the first combined output samples.

A non-transitory computer-readable storage medium having embedded therein program instructions, which when executed by one or more processors of a device, causes the device to execute a method of generating a plurality of output samples based on a plurality of input samples, the method comprising:

• generating sets of processing core output samples using a plurality of processing cores, wherein said generating is based on sets of the plurality of input samples and associated processing times for the sets of the plurality of input samples,
• processing the sets of processing core output samples by a sample combiner logic unit comprising a hierarchical tree structure comprising a plurality of hierarchical levels of combiner nodes, the processing comprising:
• combining output samples of a higher hierarchical level to generate first combined output samples;
• and
• combining at least the first combined output samples to generate second combined output samples, wherein the second combined output samples include more samples than the first combined output samples.
