ARM已启动增强型网格互连IP，适用于其高性能的屡次处理器核心，可使用小芯片和3D包装使用。
Chiplets allows separate chips to be used in the same package to provide high speed data links or stacked memory. The CMN-700 supports 144 end points for 128 cores plus chiplets and memories, rather than the limit of 64 for the previous CMN-600.
“CMN-700 [is] a key element for constructing high-performance Neoverse V1 and Neoverse N2-based SoCs,” said Chris Bergey, SVP and GM, Infrastructure Line of Business at ARM. “Platform IP is essential which is why we developed the CMN700 mesh interconnect with DDR5 support and multichip capabilities,” he said. “It adds CXL to build host or end point devices and the the other key multichip upgrade was for multi-die and chiplet integration and this will open new doors and allow more flexibility,” he said.
The mesh interconnect is intended to support scaling of cores to provide more performance, rather than running multiple threads in each core. This is key to the power consumption and security, says Berger. “We think Neoverse dedicated cores offers a better approach with more predictable performance and more immune to side channel attacks instead of shared threads,” he said.
The previous N1 chip supported 64 cores with CMN-600, and the new interconnect IP will allow the first N2 chips to have 80 cores available with versions planned with 128 cores. The Neoverse V1 chips will have up to 96 cores, said Gerber.
Marvell is using the Neoverse N2 for its next generation of OCTEON data centre chip that will begin sampling by end of 2021, providing a 3x performance over the previous parts.
