Abstract
An interface for low power, high bandwidth communications between units in a device in provided herein. The interface comprises a USB 3.0 system interface and a SuperSpeed inter-chip (SSIC) protocol adaptor configured to facilitate communications between the USB 3.0 system interface and an M-PHY interface, wherein the SSIC is configured to issue remote register access protocol (RRAP) commands through a local M-PHY to a remote M-PHY in a low speed burst mode.
Claims15
A method for implementing SuperSpeed inter-chip (SSIC) communications between units in a device, comprising
- determining if a valid remote register access protocol (RRAP) command is present;
- determining if a command phase is completed;
- determining if a high speed configuration command is ordered;
- determining if a register bank comprises valid RRAP commands;
- and
- issuing a command to close a low speed burst communications between a host and a device.
An interface for low power, high bandwidth communications between units in a device, comprising:
- a universal serial bus (USB) 3.0 system interface;
- and
- a SuperSpeed inter-chip (SSIC) protocol adaptor configured to facilitate communications between the USB 3.0 system interface and an M-PHY interface, wherein the SSIC is configured to issue remote register access protocol (RRAP) commands through a local M-PHY to a remote M-PHY in a low speed burst mode.
At least one non-transitory machine readable medium comprising instructions stored therein that, in response to being executed on a computing device, cause the computing device to:
- send RRAP commands from a register bank to an M-PHY;
- report transaction status in a status register;
- and
- determine actions to perform by examining a control register.
