CS3518 - Digital Home Processors

The Cortina CS3518 is a Network Processor that provides superior performance and functionality for Router Gateway, NAS, IP Set Top Box, VoIP and other SME and SOHO applications. The device has dual 32-bit ARM9 RISC Processors with up to 800 MIPS total performance. The device integrates a full featured hardware crypto engine, two 10/100/1000 Ethernet MACs, dual USB 2.0 hosts or clients, dual IDE or SATA interfaces, a 66 MHz 32-bit PCI interface, and direct interfaces to color LCD and SLIC modules. The device also includes an intelligent and programmable power management unit for portable system applications.

The dual CPU architecture allows maximum system throughput and flexibility for application software development. Cortina provides a complete software suite that includes a fully functional software stack running on the first CPU, a small footprint real-time OS running on the second CPU, an inter-processor communication layer, and a complete development platform for code development and integration. This architecture is ideal for customers who demand high performance DSP, MPEG, multi-media management, TCP/IP Offload Engine or other applications.

The Security Acceleration Engine has a performance of over 600/200 Mbps running DES/3DES ; 237/197/169 Mbps running 128/192/256bits AES. This Security Acceleration Engine also performs hardware acceleration on CCMP and RC4 encryption; SHA1, MD5, HMAC-SHA1, and HMAC-MD5 authentication. The hardware crypto engine in the Cortina CS3518 allows data encryption on network storage, DRM in multimedia IP protection, and VPN to run at full wire speed.

The embedded dual 10/100/1000 MACs with the industry standard MII and RGMII allow the system integrators the flexibility of configuring a traditional NAS server system with one or two channel 10/100/1000 Ethernet PHYs, or a NAS server plus router gateway capabilities with one WAN port and one LAN port. The Layer 2-4 hardware switching and Layer 2-7 packet classification enable high end router gateway designs for Fiber-to-the-Home, GPON, and other high speed internet infrastructures carrying data, voice, video and on-line commerce, and gaming services.

The dual IDE cores, single IDE physical interface, and dual SATA interfaces allow high performance data throughput and hard drive selection flexibility. The attached hardware XOR engine enables wire-speed RAID5 operations.

Performance enhancing hardware acceleration circuitries are included in the EMAC, DDR controller, and IDE control modules. The complete hardware acceleration engine improves the overall throughput in TCP/IP/UDP transmit, receive, and SAMBA read and write operations without the intervention of the CPU.

The dual USB 2.0, configurable to be the host or client by pin configuration or software, allows maximum flexibility in peripheral device integration, such as flash memory, USB control devices, and USB 2.0 hard drives.  

The PCI bus supports four master devices. The system integrator can add MPEG encoder, decoder, WiFi 802.11a/b/g/n access point, and other devices to deliver a complete wireless IP Set Top Box or Media Server product.
