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.

Descriptor transfer logic

Testing one or more memories of a device includes receiving one or more first repair records from one or more built-in self-testers of a device having one or more memories. A built-in self-tester is associated with a memory, and a first repair record describes a first repair at a memory. A first repair signature corresponding to the first repairs at the memories is generated from the first repair records, and then is recorded. One or more second repair records are received from the built-in self-testers, where a second repair record describes a second repair at a memory. A second repair signature corresponding to the second repairs at the memories is generated from the second repair records. The second repair signature is compared with the first repair signature. The device is evaluated in response to the comparison.
