LVDS Tunneling Protocol and Interface (LTPI) is a soft IP introduced in the DC-SCM 2.0 Specification to facilitate the tunneling of low-speed signals between the host platform module (HPM) and secure control module (SCM) through the low-voltage differential signaling (LVDS) interfaces.
Next-Gen Protocol for DC-SCM 2.0
The LTPI interface is designed for tunneling various low-speed signals between the Host Processor Module (HPM) and the Secure Control Module (SCM). It can be implemented with two FPGA or CPLD devices for configurations with typical BMC devices.
Both HPM and SCM work together to manage and secure communication within a system by tunneling control signals over the LVDS interface within the system.
