摘要： In accordance with the present disclosure, a method may include receiving a delay measurement message frame at a responder maintenance end point from a controller maintenance end point. The method may further include writing an ingress time value to the delay measurement message frame upon receipt of the delay measurement message at the responder maintenance end point. The method may also include generating a delay measurement response frame based on the delay measurement message frame, the delay measurement response frame comprising an egress timestamp field having a value equal to the difference between a time at which the delay measurement response frame is transmitted from the responder maintenance end point and a time represented by the ingress time value. The method may additionally include transmitting the delay measurement response from the responder maintenance end point to the controller maintenance end point.

摘要： A digital signal processing unit with an array of digital signal processors (DSP) is provided with a recirculation path for data sequences which cannot be fully processed by a single pass through the array. An input programmable gate array (PGA) controls distribution of data sequences to individual DSPs for processing and an output PGA controls their recollection. The recirculation path is provided by a recirculation register which is write enabled by the output PGA and read enabled by the input PGA.
