We were in the heart of Silicon Valley last week for ARM® TechCon 2013. Ranked as one of the top events in the embedded industry, TechCon is both a conference and expo for ARM® and its affiliates. As a major partner with ARM®, Samsung was prominently featured in both the Expo Hall and speaking sessions during the convention.

Expo Hall
Our booth in the Expo Hall featured a variety of demos highlighting various aspects of the Exynos 5 Octa SoC. Among the demos was a graphics performance comparison, a station highlighting big.LITTLE technology within the 5 Octa, and a section dedicated to Exynos 5420-powered community boards from Hardkernel and Insignal. Here's a brief summary of the demonstrations we had in the Expo Hall as well as a few pictures from the event:

  • Introduction to Heterogeneous Multi Processing Demo: This station introduced our HMP solution for the Exynos 5 Octa through a program which showed real time core activities within an Exynos 5420-powered tablet. In the demonstration, we ran various applications including game and office programs on the Exynos-powered tablet, and the real time core activities were shown on a laptop display. The simulation graphically represented the HMP solution allocating various tasks to the appropriate CPU cores and selecting the right combination of cores for a variety of different use cases.

  • Processing Power Benefits of Heterogeneous Multi Processing Demo: In order to illustrate the benefits of the new HMP solution in the Exynos 5 Octa, we set up a benchmark program which compared a CPU cluster switching solution vs. an HMP solution. The program clearly showed that an HMP solution, which could engage various combinations of CPU cores based on workload, was more efficient than a cluster switching solution.

  • Graphics Performance Demo: This demonstration utilized various simulations to show the superior graphics enabled by Open GL® ES 3.0 and GPU Compute on an Exynos 5 Octa (5420) platform using an ARM® Mali™ GPU. The station also included a Unity Chase gaming simulation to exhibit mobile gaming graphics capability.

  • Widcon Technology Demo: This presentation focused on the new Widcon technology, formally introduced as Wide I/O technology, for Exynos processors. The demonstration highlighted the structural differences between Widcon technology and conventional memory interface technology, and explained how Widcon technology is designed to maximize both memory bandwidth and thermal dissipation. A comparison simulation also demonstrated how an AP solution with Widcon technology consumes less power than a conventional AP solution.

Speaking Sessions
Several speaking sessions during ARM® TechCon were focused on Exynos processors. Here's a brief summary of each:

  • Samsung Breathes Life into the Exynos 5 Octa with a New Innovation: This session by Jangho Pae focused on a new Widcon technology for Exynos processor that is being developed by Samsung. Widcon technology directly connects Exynos processor and Wide I/O memory without conventional PCB and wires through Samsung's innovative TSV (Through Silicon Via) technology. The solution is designed to increase memory bandwidth, and aims to increase the speed of data transfer and reduce power consumption. More details will be available on this technology at a later date.

  • Unleashing the Possibilities of Heterogeneous Multi Processing with Samsung Exynos Processors: This session by Ian Huh was dedicated to the Heterogeneous Multi Processing (HMP) solution that was recently released for the Exynos 5 Octa. The presentation highlighted the maximum performance with energy efficiency that is enabled by HMP, and explained how the system efficiently assigns tasks to different combinations of CPU cores based on workload.
