• and
• submitting the active request from the selected service requestor to one of the at least one engine capable of processing the job.

A non-transitory computer readable medium comprising:

• a plurality of executable instructions that when executed by an apparatus for scheduling arbitration among a plurality of service requestors cause the apparatus to:
• generate requests to be enqueued into the plurality of service requestors by at least one host and at least one engine, the at least one engine comprising at least one digital signal processor and/or at least one hardware accelerator, wherein each request comprises a job or a non-job;
• perform, by a job arbitrator and assignor communicatively coupled to the plurality of numbered service requestors, the actions of:
• designate among the plurality of service requestors all the service requestors that have an active request at a top entry indicating that a job is ready to be processed and that at least one engine capable of processing the job is available;
• determine whether at least one of the designated service requestors has an un-served status indicator which is set;
• select one of the at least one designated service requestors in accordance with a pre-determined policy;
• clear the un-served status indicator for the selected service requestor in response to the determination being positive;
