Xuantie launches the first multi-cluster interconnect IP XL100 that supports cache coherence

According to news from this website on July 3, XuanTie today officially announced the launch of the first multi-Cluster (cluster) interconnection IP that supports cache consistency - XL100. Multi-Cluster interconnection is a common technology in server distributed systems that allows multiple Clusters to communicate over the network. According to reports, XL100 provides customers with 8~32 core processor expansion solutions, supporting large and small core configurations. XL100 can reduce the bandwidth and software programming difficulty required for multi-Cluster system interconnection data transmission, reduce additional Cache accesses and optimize system power consumption. At the same time, XL100 provides interfaces for multiple IO devices to access the Cache to simplify data exchange between CPU and IO and improve performance. Multi-core interconnection involves efficient exchange and management of data, among which cache consistency is particularly important. This technology can ensure consistency when multiple processor cores access shared memory to reduce software control complexity and lay the foundation for realizing high-performance multi-core systems. XL100 is equipped with XT-Link - a network-on-chip (NoC) interconnection technology that supports multi-processor cache coherence. This technology naturally supports Xuantie multi-Cluster and has the following advantages: supports L2 & L3 collaborative fine-grained allocation and supports hardware optional L3 Cache supports Cache half power-off and full power-down and supports up to 7 device coherence ports (DCP). Xuantie The cooperation of Iron C920 and C908 processors can support other Masters using the standard ACE protocol to work together in the future.

Currently, Xuantie XL100 can be mainly used in intelligent interactive terminals, AR/VR and other scenarios with high energy efficiency requirements, as well as artificial intelligence, autonomous driving, network communications and other fields with high concurrent computing power requirements. The specifications are attached on this site Table:
