FM1010 - Six-interface SPI-4.2 Interconnect Chip

The only product of its kind, the PivotPoint FM1010 six-interface System Packet Interface Level 4 Phase 2 (SPI-4.2) Switch Chip is a high-performance switch-based solution for seamlessly and intelligently interconnecting multiple chips containing the SPI-4.2 interface, enabling designers to deliver sophisticated systems while significantly reducing costs, increasing system flexibility, and reducing time to market.

The PivotPoint FM1010 converts a fixed-configuration half-duplex daisy-chain of devices with SPI-4.2 interfaces (such as NPUs, traffic managers, co-processors, search engines, custom ASICs, and FPGAs) into a dynamically-reconfigurable full-duplex resource pool, enabling more efficient use of the silicon resources, and eliminating the custom glue logic that often accompanies complex system designs.

FM1010 Features

• Six independent System Packet Interfaces (SPI-4.2)
  • Each is an independently-clockable dual-simplex interface
  • Each can support data rates up to 14.4 Gbps
  • Dynamic or static phase alignment
  • LVTTL status channel
  • Configurable packet buffer (16KB ingress; 16KB egress) per interface
  • Up to 256 flow-controlled channels per interface
• Fully-connected non-blocking switching
  • Soft-configurable interface and channel assignment
• 16-bit standard CPU interface
• JTAG and boundary scan support
• Up to 3x internal overspeed
• Built-in fine-grain flow control
• 1.0 V core, 2.5 V LVDS, and 3.3 V LVTTL operation
• Independent enable / disable control for each interface (reduces power)
• Loopback control for each interface
• Statistics and error reporting
• Modest and flexible power profile
  • <2.5 W per active interface, at full speed
  • Power scales linearly on activity
• 130 nm CMOS process technology
• 1232-ball Ball Grid Array package

FM1010 Applications

The FM1010 can be used at the blade level and for small modular systems (appliances and "pizza boxes") in high-speed communications and computing applications where the SPI-4.2 interface is used to interconnect the silicon resources in the system.

• Ethernet Switches and Routers
• SAN Switches and Gateways
• Enterprise Compute Servers
• Multi-Service Platforms
• Enterprise Firewalls and Gateways
• Enterprise Services Appliances

FM1010 Evaluation Platform

The modular Evaluation Platform for the PivotPoint FM1010 SPI-4.2 Interconnect can be used to rapidly and exhaustively evaluate the performance and flexibility of the FM1010, simulate a variety of configurations of interconnected SPI-4.2 devices, and simplify the evaluation of other complementary components for use in the target system. The platform can be configured with any mixture of Fulcrum-supplied physical interface modules, network processing modules, signal probe modules, and field-programmable protocol generator/analyzer modules. Additionally, the platform can be extended with chip modules and interconnected evaluation platforms supplied by the user to test specific architectures and devices, and to rapidly prototype complete systems.
