AppliedMicro also offers the industry’s first integrated software programmable co-processor within the APM86491 Catalina SoC for application specific customizable offloads. SLIMpro allows AppliedMicro to provide the industry’s first receive-side TCP offload engine to further improve network throughput. Performance improves more than 100 percent in applications such as NAS through the use of a TCP receive side offload engine. Performance is also provided by Catalina’s 1 GHz Power Architecture® 465 CPU featuring a dual issue, out-of-order processor core. The net result for consumers is uninterrupted performance with no stalls during data transfers. Furthermore, bandwidth multiplexing, speed and coverage range of IEEE 802.11ac wireless solutions are improved as On-The-Go (OTG) sharing becomes more pervasive through smart phones, tablets, laptops and HD displays.
The SLIMpro co-processor responds to network control packets while the main CPU and the rest of the SoC remain in a deep sleep mode, operating at less than 250mW to further reduce Total Cost of Ownership. The SoC operates at less than 3W under typical operation conditions to support Power-over-Ethernet (POE) requirements. Low power operation also eliminates cooling fans and heat sinks from system designs for reduced bill-of-material cost.
Catalina features an advanced hardware-based QoS engine with support for DPI (Deep Packet Inspection) for prioritization of real-time and latency sensitive traffic. The SoC leverages its queue manager and classifier to perform bandwidth management with 256 queues, 1024 search filters, and 128 traffic policers and shapers. This provides a richer video experience while voice and web traffic remain unaffected by multiple simultaneous streams and applications.
Catalina provides 64-byte L2 bridging performance with a classifier offload equal to 762Mbps, delivers 100 percent Ethernet line rate performance with no CPU utilization. IP forwarding 64-byte performance with classifier offload delivers 621Mbps at 100 percent CPU utilization. IP forwarding 1500-byte performance with classifier offload delivers 986Mbps at zero percent CPU utilization. Catalina’s Robocopy NAS writes equal 110 Megabytes per second (MBps) at 80 percent CPU utilization. Iometer NAS writes are 110 MBps at 35 percent CPU utilization and Iometer NAS reads are 108 MBps at 40 percent CPU utilization.
