MoSys (NASDAQ: MOSY), a leader in semiconductor solutions that enable fast, intelligent data access for network and communications systems, today announced the newest member of the Bandwidth Engine® family of products that accelerates intelligent networking functions. The Bandwidth Engine 2 – Macro delivers the highest access rate and throughput of any single device today coupled with offload accelerators for single rate and two rate three color marker (srTCM, trTCM) metering, statistics, and accounting applications.
As network performance and feature requirements continue to scale, architectural improvements are required. Networking equipment has transitioned to highly parallel, multi-threaded processing System-on-Chip complexes which require an insatiable amount of memory bandwidth. The Bandwidth Engine 2 family has three purpose-built variants, Burst, Access and Macro, to meet these growing needs and is intended for high-reliability, carrier-grade applications.
Using sixteen 15 Gigabits per second (Gbps) SerDes lanes, the Bandwidth Engine 2 interface operates at 480 Gbps, providing the host with up to 384 Gbps CRC protected, effective data throughput. This represents an unprecedented 80% overall efficiency, well beyond the capability of standard memory subsystems and alternative serial interface solutions, while using less than half of the board area, interface pins, and power resulting in substantial system-level cost savings.
The new device, MSR820, with its on-board accelerators, is capable of fire-forward operations which can update records entirely internal to the device, reducing the number of memory bus transactions from six down to one, as well as relieving the host of the computations required for the update. The MSR820’s macros can be saturated using only 8 SerDes lanes, further reducing the power, pincount and host resources. The macro functions can retire entire operations in under 30 nanoseconds (ns), far quicker and at substantially lower power than alternative solutions, making Bandwidth Engine 2 – Macro a device unique to the industry in its capabilities.
