OPENEDGES unveils high performance & low power GDDR6 controller IP

November 4, 2019 -- OPENEDGES Technology, Inc. the leading IP provider of Memory Subsystem IP today announced the release of GDDR6 memory controller IP.

OPENEDGES is the only IP company providing both DDR controller (OMCTM) and Network-on-Chip (OICTM) IP. OPENEDGES' ORBITTM memory subsystem IP has tightly coupled DDR controller and Network-on-Chip (NoC) interconnect IP resulting in complete memory subsystem IP. This combination enables more intelligent transaction scheduling that considers both the bandwidth and latency requirements of memory access requests by utilizing its coverage of the SoC’s entire memory subsystem.

OPENEDGES’ DDR Memory Controller (OMCTM) has been supporting DDR3/4, LPDDR3/4(X) and now adds a GDDR6 solution. OPENEDGES’ GDDR6 controller features very high DRAM utilization with a proprietary out of order scheduling algorithm. It has a highly optimized pipeline architecture that supports data rates of 18Gbps or more. It also supports extremely low power consumption with dynamic clock frequency change. OPENEDGES will provide this GDDR6 controller as a stand-alone IP or as a memory subsystem IP together with its own NoC bus interconnect IP (OICTM). The Network-on-Chip Interconnect (OICTM) and GDDR6 controller IP are designed in a way that can be very tightly coupled. This combined memory subsystem IP brings significant synergy in terms of performance, QoS and low power consumption.

“We are very excited to release OPENEDGES GDDR6 controller IP. We have seen many customers - struggling with DRAM bandwidth due to separate IP system between the bus interconnect and GDDR6 controller. GDDR6 will be widely used for AI/ML/Data Center, Automotive, Server & HPC and often when DRAM bandwidth will be a bottleneck for SoC system in these verticals. We are confident that our integrated GDDR6 controller & NoC solution will solve those issues” said, CEO of OPENEDGES, Sean Lee.

OPENEDGES also provides AI accelerator IP (ENLIGHTTM), which is also tightly integrated with the memory subsystem IP. ENLIGHTTM will be officially released in early 2020.


OPENEDGES is a semiconductor IP provider for smart computing, empowering the Internet of Smart Things. OPENEDGES is committed to democratizing artificial intelligence technology at edge devices. OPENEDGES delivers IPs in two key technology areas of smart computing; highly efficient Artificial Intelligence Acceleration and high-performance Memory Subsystem(s). Aided by the synergy of these two technologies, OPENEDGES offers a sorely needed boost in performance, efficiency and reliability for the Internet of Smart Things. ORBITTM DDR memory controller IP currently supports DDR3, DDR4, LPDDR3, LPDDR4(X) and GDDR6. Support for LPDDR5, DDR5 and HBM2(E) will be available soon.
