Introducing XpressCCIX-AXI, CCIX Controller IP with AMBA AXI Interconnect

 
 
 
 

        


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.
