Common Acronyms and Definitions

  • MSPS or MS/s megasamples per second, or millions of samples per second
  • kSPS or kS/s kilosamples per second, or thousands of samples per second
  • SPS or S/s samples per second
  • V volt
  • mV millivolt, or a thousandth of a volt
  • s seconds
  • ms millisecond, or a thousandth of a second
  • us microsecond, or a millionth of a second
  • ns nanosecond, or a billionth of a second
  • I2C Inter-Integrated Circuit
  • SPI Serial Peripheral Interface
  • SWI Single Wire Interface (Atmel)
  • CAN Controller Area Network
  • HDLC High-level Data Link Control
  • HDMI CEC High-Definition Multimedia Interface Consumer Electronics Control
  • I2S Inter-IC Sound
  • PCM Pulse-Code Modulation
  • JTAG Joint Test Action Group
  • LIN Local Interconnect Network
  • MDIO Management Data Input/Output

  • SMBus System Management Bus
  • SWD Serial Wire Debug
  • UNI/O (not an acronym), a protocol made by Microchip
  • USB LS/FS Universal Serial Bus Low Speed / Full Speed
  • Baud rate data rate measured in bits per second
  • MSB most significant bit
  • LSB least significant bit
  • Parity additional information added to the data to provide error detection information
  • processing backlog In the Saleae software, the data recorded from the device is transformed to the storage format as it is recorded, in near-real time. If the process is unable to keep up with the recording in real time, the processing backlog will grow as unprocessed data are buffered.
  • trigger backlog In the Saleae software, when the trigger is used, the processed data are then fed into the trigger in near real-time. If the trigger thread is unable to process the already transformed data in real time, the trigger backlog will grow as processed (but not yet searched) data are buffered.
