BURST PERFORMANCE
The burst functionality of GSI Technology’s GSR622 provides up to 400Gbps CRC-protected, data throughput. Burst length is selectable on a cycle-by-cycle basis for maximum flexibility.

TRUE RANDOM ACCESS
GSI Technology’s Bandwidth Engine GSR720 brings fast, intelligent memory access to network processing chipsets. The GSR720 integrates high density memory, a high speed serial interface, and 90% efficient transport protocol. The flat, dual ported partition addressing enables fully random, simultaneous reads and writes to any memory location while maintaining full data coherency. 

RECORD PROCESSING OFFLOAD ENGINE
GSI Technology’s Bandwidth Engine GSR820 adds on-board intelligence to the burst and access abilities of the GSR622, providing intelligent offload for Counting, Statistics, Metering and Atomic operations. The highly parallel array architecture is capable of up to six billion memory accesses per second and can be saturated with only 8 SerDes lanes when utilizing the on-board macro functionality. Coupled with the efficient, packetized, serial interface, it enables support of multiple applications within the 576Mbit footprint.
