Compute module hosts single-chip, quad-core Intel Atom E3800

October 10, 2013 // By Graham Prophet
congatec’s Qseven-format conga-QA3 provides twice the performance over its predecessor plus an optimised product lifespan assisted by use of all-ceramic capacitors

Features include an ample L2 cache, which can be shared by multiple cores, and a much faster Intel HD graphics unit compared with the previous generation. The modules support the Intel Advanced Encryption Standard New Instructions (Intel AES-NI) set allowing developers to offload compute-intensive AES (Advanced Encryption Standard) packaging and encryption routines into hardware, reducing the load on the CPU cores.

The conga-QA3 comes in five different Intel Atom processor-based versions (formerly codenamed “Bay Trail”) for high scalability. It ranges from the entry-level single-core 1.46 GHz E3815 Atom processor with power consumption of 5W, up to the quad-core E3845 at 1.91 GHz and 10W. The Qseven modules are each equipped with 2 GB of DDR3L memory and up to 16 GB eMMC 4.5 for mass storage. Depending on which processor is used, versions with 8 GB of RAM are available. The integrated graphics are significantly more powerful than the previous model and support DirectX 11, OpenGL 3, OpenCL 1.2 and high-performance, flexible hardware decoding to decode even multiple high-resolution full HD videos in parallel. Up to 2,560 x 1,600 pixels with DisplayPort and 1,920 x 1,200 pixels with HDMI are natively supported. It is also possible to connect up to two independent display interfaces via 2x 24-bit LVDS.

Wnative USB 3.0 support, the modules achieve fast data transmission with low power consumption. One of the five provided USB 2.0 ports is configured as USB 3.0 SuperSpeed. Three PCI Express 2.0 lanes and two SATA interfaces with up to 3 Gb/sec enable fast and flexible system extensions. The Intel I210 Ethernet Controller provides software compatibility. Completing the feature set are: MIPI camera interface, I 2C bus, LPC bus and Intel High Definition Audio.
