Abstract:
A measurement data recording system includes a microprocessor, a first switch and a second switch. The first switch sends a trigger signal to trigger a digital measurement instrument sends a measurement data. The microprocessor detects the trigger signal aroused by the first switch, receives the measurement data, and records it into the memory card. The microprocessor also detects a trigger signal aroused by the second switch and deletes the measurement data in the memory card. A method for recording the measurement data includes steps of detecting the trigger signal, detecting a status of the memory card, detecting a status of a data file in the memory card, receiving the measurement data and recording it into the data file while the trigger signal being aroused by the first switch, and deleting the measurement data recorded in the data file while the trigger signal being aroused by the second switch.
Abstract:
A packet processing accelerator comprises a programmable packet classification module, a programmable flow control module, and a programmable packet header modification module. The programmable packet classification module is configured to receive a data packet and generate a start location of each protocol header of the data packet and a first index. The first index indicates classification of the data packet. The programmable flow control module is configured to generate a code of an output port and an action code according to the start location of each protocol header of the data packet and the first index. The programmable packet header modification module is configured to modify content of a plurality of protocol headers of the data packet according to the action code and to send the modified data packet to an output port according to the code of the output port.
Abstract:
A system and method for voice quality analysis include the ability to receive packets in a voice stream and to generate a receipt indicator for the packets. The system and method also include the ability to substitute a reference voice sample for the voice data in the packets and to compare the voice data in the voice-substituted packets to the reference voice sample to determine voice quality.
