7.14 HyperLink Peripheral
The TMS320C6672 includes the HyperLink bus for companion chip/die interfaces. This is a four-lane SerDes
interface designed to operate at up to 12.5 Gbaud per lane. The supported data rates include 1.25 Gbaud,
3.125 Gbaud, 6.25 Gbaud, 10 Gbaud and 12.5 Gbaud. The interface is used to connect with external accelerators.
The HyperLink links must be connected with DC coupling.
The interface includes the Serial Station Management Interfaces used to send power management and flow messages
between devices. This consists of four LVCMOS inputs and four LVCMOS outputs configured as two 2-wire output
buses and two 2-wire input buses. Each 2-wire bus includes a data signal and a clock signal.
7.14.1 HyperLink Device-Specific Interrupt Event
The HyperLink has 64 input events. Events 0 to 31come from the chip level interrupt controller and events 32 to 63
are from queue-pending signals from the Queue Manager to monitor some of the transmission queue status.
