摘要

“TALON”架构的提出是为了满足平方公里阵列第1阶段(SKA1)中望远镜、相关器和波束形成器(Mid. CBF)前所未有的处理要求和灵活性。TALON架构的高性能硬件平台集成了TALON线路可替换单元(lru)的两种变体;TALON-SX和TALON-MX。每个LRU具有单个Intel Stratix-10 FPGA, 2个DDR4 DIMM模块，4个100GE QSFP28端口和48个26 Gbps双向光通道，可连接到定制光背板。每个LRU最大可提供7tmac /s的处理能力、512gb /s的内存带宽和1.648 Tb/s的I/O容量。

High-performance hardware platform for the square kilomtre array mid correlator & beamformer

The ‘TALON’ architecture has been proposed to meet the unprecedented processing requirements and flexibility required for the Square Kilometre Array-Phase-1 (SKA1) Mid telescope, Correlator & Beamformer (Mid. CBF). The high-performance hardware platform of the TALON architecture incorporates two variants of TALON line-replaceable-units (LRUs); TALON-SX and TALON-MX. Each LRU features a single Intel Stratix-10 FPGA, 2 DDR4 DIMM modules, 4 100GE QSFP28 ports and 48 26 Gbps bi-directional optical channels that connect to a custom optical-backplane. Each LRU facilitates up to 7 TMAC/s of processing capability, 512 GB/s of memory bandwidth and 1.648 Tb/s of I/O capacity.
