USB 3.2時代來臨:將會全面放棄Type-A接口
在USB3.1 Gen2的使用下,在2017年9月底就宣布了USB 3,2 Gen 2的規(guī)范.
· USB 3.2 Gen 1x1 - SuperSpeed, 5 Gbit/s (0.625 GB/s) data signaling rate over 1 lane using 8b/10b encoding, the same as USB 3.1 Gen 1 and USB 3.0.
· USB 3.2 Gen 1x2 - SuperSpeed+, new 10 Gbit/s (1.25 GB/s) data rate over 2 lanes using 8b/10b encoding.
· USB 3.2 Gen 2x1 - SuperSpeed+, 10 Gbit/s (1.25 GB/s) data rate over 1 lane using 128b/132b encoding, the same as USB 3.1 Gen 2.
· USB 3.2 Gen 2x2 - SuperSpeed+, new 20 Gbit/s (2.5 GB/s) data rate over 2 lanes using 128b/132b encoding.
In May 2018, Synopsys demonstrated the first USB 3.2 connection, where a Windows PC was connected to a storage device, reaching a speed of 1.6 GB/s average.
USB 3.2 is supported with the default Windows 10 USB drivers and in Linux Kernel
Synopsys首次公開演示了USB 3.2.
Synopsys這次演示的USB 3.2基于HAPS-80 FPGA硬件原型平臺,單通道帶寬為10Gbps,雙通道則可以達到USB 3.2所需的20Gbps。HAPS平臺通過PCI-E連接PC,并作為大容量存儲設備。
在這次演示中,USB 3.2跑出了1.6GB/s的成績,尚未達到標準的最高值,還有發(fā)揮的潛力;另外,值得一提的是,USB 3.2將采用Type-C接口,目前依然流行的Type-A接口將會在USB 3.2時代徹底被拋棄.
相信在不久的將來,數(shù)據(jù)接口將會逐漸被統(tǒng)一,變得更加方便靈活,傳輸速率也會越來越快,為用戶節(jié)省大量的時間.
