While heterogeneous computing is making its way into high end datacenter applications covering A.I, Network Processing, Storage Off-Load etc., the need for cache-coherent interconnect between compute elements has increased significantly. This lead to the creation of the Cache Coherent Interconnect for Accelerators (CCIX) protocol in 2017. Today, we are introducing our latest product: XpressCCIX-AXI, our controller IP for PCIe 5.0/4.0 with support for CCIX Extended Speed Mode (ESM) supporting speeds up to 32GT/s in PCIe 5.0 mode and up to 25GT/s in CCIX 1.0 mode.
XpressCCIX-AXI Controller IP
XpressCCIX-AXI™ is a configurable and scalable PCIe controller Soft IP designed for ASIC and FPGA implementation. The XpressCCIX-AXI Controller IP for PCIe 5.0 supports the PCI Express 5.0, 4.0, and 3.1/3.0 specifications, as well as the PHY Interface for PCI Express (PIPE) specification and the AMBA® AXI™ Protocol Specification. It also supports the CCIX Extended Speed Mode as defined in the CCIX Base Specification Rev. 1.0. The IP can be configured to support endpoint, root port, and dual-mode topologies, allowing for a variety of use models, and exposes a configurable, flexible AMBA AXI interconnect interface to the user.
