Abstract

A processing engine includes descriptor transfer logic that receives descriptors generated by a software controlled general purpose processing element. The descriptor transfer logic manages transactions that send the descriptors to resources for execution and receive responses back from the resources in response to the sent descriptors. The descriptor transfer logic can manage the allocation and operation of buffers and registers that initiate the transaction, track the status of the transaction, and receive the responses back from the resources all on behalf of the general purpose processing element.
