The innovative architecture driving the highest utilization and lowest latency 

DDR Memory Controller, OMC


Get to know the ORBIT Memory Subsystem IP that consists of an interconnect, memory controller, and PHY IPs that work in unison to create maximum system synergies. 

Achieve exceptional connectivity performance and design flexibility using an automated end-to-end interconnect generation flow. 

Meet high-speed memory PHY IPs that deliver the lowest power and area, enabling solutions across AI/ML, high-performance computing (HPC), and automotive.


ORBIT Memory Controller, OMC

Delivers excellent performance in addition to high utilization and ultra-low latency, achieved by its proprietary out-of-scheduling algorithm and high-speed implementation. Designed to address the needs of next-generation SoCs, the OMC saves a significant amount of area and power while supporting the highest levels of the DRAM bandwidth.

The OMC integrates seamlessly with the OPENEDGES ORBIT DDR PHY(OPHY) and ORBIT On-Chip Interconnect (OIC) to deliver a complete memory subsystem. The OMC also supports third-party DDR PHYs, providing full functional verification for use with any PHY implementation.
