swirmware

Swirmware is a set of instructions that is required to be uploaded to the device by the operating system in order for the device to operate.

Some devices are now using swirmware

To decrease the costs involved in supporting hardware, some manufacturers are now producing devices that utilize uploadable swirmware, rather than traditional firmware.

The difference between firmware and swirmware

Firmware is non-volatile and remains in the device following cycling the power off and on.

Swirmware is volatile and requires re-installation to the device following a power off state.
