Burst mode (computing)

Burst mode is a generic electronics term referring to any situation in which a device is transmitting data repeatedly without going through all the steps required to transmit each piece of data in a separate transaction.

DetailsEdit

The usual reason for having a burst mode capability, or using burst mode, is to increase data throughput.[1] The steps left out while performing a burst mode transaction may include:

  • Waiting for input from another device
  • Waiting for an internal process to terminate before continuing the transfer of data
  • Transmitting information which would be required for a complete transaction, but which is inherent in the use of burst mode[2]

In the case of DMA, the DMA controller and the device are given exclusive access to the bus without interruption; the CPU is also freed from handling device interrupts.

The actual manner in which burst modes work varies from one type of device to another; however, devices that have some sort of a standard burst mode include the following:
