Abstract:
1. A method of broadcasting data to multiple devices across a system bus that does not normally support broadcast transfers, the method comprising: establishing handshaking between a first device on the system bus and a second device on the system bus; transmitting data over the system bus from the first device to the second device, in response to handshaking being established; receiving the data at the second device and at one or more other devices on the system bus; determining, by the one or more other devices, that the one or more other devices are unable to continue receiving the data at the rate at which the data is being transmitted; receiving, by the second device, an indication of the determination; transmitting a signal over the system bus from the second device to the first device, in response to receiving the indication; and stalling, by the first device, the transmission of the data over the system bus in response to the first device receiving the signal, wherein handshaking remains established between the first device and the second device during the stalling of the transmission.
