aTempo was founded in April this year in response to the new technology barriers created by wide ranging industry moves to next-generation data rates for serial links within, and external to, PCs. These include USB 3.0 at 4.8 Gbps; PCI Express 3.0 at 8 Gbps; FireWire 3200 at 4 Gbps and both SAS and SATA moves to 6 Gbps.
aTempo’s patent pending technology makes these data rates practical using lowest cost cables, lowest cost circuit boards, lowest cost connectors and low cost, low power silicon.

This is achieved using the combination of the company’s novel signal processing IP and detailed CMOS circuit implementation IP, which together offer a new level of performance for multi-gigabit per second serial links.

The combination is key. At the data rates involved, CMOS implementation non-idealities can easily dominate the performance of multi-gigabit per second signal processing circuits, which then falls very short of that anticipated by naïve analysis.

aTempo was founded Nick Weiner who has been in the industry for more than two decades. Weiner was co-founder of Phyworks, known for their leading optical interface ICs, including their equalizing receiver developed for 10 Gigabit per second Ethernet standard, 10GBASE-LRM.

The company, based at the University of Bristol’s SETsquared Business Acceleration Centre, is very pleased to have been accepted onto a new programme for high growth-potential semiconductor start-ups in the South West of England, called FASTtrack. This initiative is run by Silicon South West in conjunction with SETsquared and is supported by UK Trade and Investment (UKTI) and the South West Regional Development Agency.
