So, seems the signal thread performance of A57 core will be close to that of Intel Yonah core (Core microarchitecture), and a bit lower than that of Merom core (Core 2 microarchitecture), if SpecInt2000 can be taken linearly, which was designed to.
SpecInt2000 scores (http://www.spec.org/cpu2000/results/cint2000.html):
Core Duo T2600@2.17G = 1796
Core 2 Duo T7400@2.17G = 2284
They were released in 2006 (Jan and Aug?), and TDPs are 31W and 34W respectively.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Are the design challenges the same as with embedded systems, but with a little developer- and IT-skills added in? What do engineers need to know? Rick Merritt talks with two experts about the tools and best options for designing IoT devices in 2016. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
