2.1 Introduction
Q7-928 is a CPU module, in Qseven
frequencies up to 1.2GHz, which is ideal for applications requiring multimedia capabilities and/or high levels of parallel computing.
Along with programmable CPLD Lattice LCMXO640, the board offers a very high level of integration, both for all most common used peripherals in ARM world and
for bus interfaces normally used in x86 world, like PCI-Express and S-ATA.
All this comes out in the extremely reduced space offered by Qseven
This solution allows combining the advantages of a standard, ready-to-use board, like Qseven
processors like NXP i.MX6 processor, in its different versions (Single Core, Dual Core, Dual Core Lite, Quad Core)
Moreover, NXP i.MX6 processors integrates three separated accelerators for 2D, OpenGL
™
performances (OpenVG
accelerator is not available with i.MX6 Solo and Dual Lite processors).
The board is completed with up to 4GB DDR3 (up to 2GB with i.MX6 Solo) directly soldered on board, and one eMMC Flash Disk, directly accessible like any
standard Hard Disk, with up to 32GB of capacity.
The board can support up to three independent displays using dedicated video interfaces of the module: the first one, is a 24 bit Single/Dual Channel LVDS
interface, which can be configured to work as two independent 24 bit Single Channel interfaces. The other display interface is i.MX6's native HDMI port. Please be
aware that using i.MX6 Solo and i.MX6 Dual Lite processors, only two independent displays at a time are supported.
HW video decoding, in the most common video coding standards (i.e., H.264, MPEG2, MPEG4, DivX, RealVideo and other), is supported.
Many other features available through the standard Qseven
PCI-Express x1, SATA (not available with i.MX6 Solo and Dual Lite), 2 x PWM Channels, Audio, GPI/Os, one USB OTG port.
USB Hi-Speed interface drives an SMSC USB2514 USB2.0 Hi-Speed USB Hub Controller, which allows the board to have 4 USB 2.0 Host Ports.
RGMII i.MX6 native interface is internally carried to a Micrel KSZ9031RN Ethernet Transceiver, allowing the implementation of a Gigabit Ethernet interface
The Lattice CPLD mounted on board, makes available LPC Bus, one additional PWM Channel and one Timer input.
For external interfacing to standard devices, a carrier board with a 230-pin MXM connector is needed. This board will implement all the routing of the interface
signals to external standard connectors, as well as integration of other peripherals/devices not already included in Q7-928 CPU module.
Furthermore, an FFC/FPC connector is provided to give access to Image Processing Unit of i.MX6 processor, which supports multiple formats and can be
connected to a wide variety of image sensors for video-preview, video-record and frame grabbing applications. Interfacing is possible using the direct parallel
interface or the integrated MIPI/CSI interface (both available on the same connector).
