Graperain Single Board Computer Solution for HMI and POS

Processor selection

It is useful to understand the processor's performance requirements when selecting Graperain embedded processors for industrial applications. However, special attention should be paid to the human-machine interface () (especially with video, 2D and 3D graphics) the performance requirements of a realistic estimate. You should also pay attention to other considerations, such as peripheral combinations. Once the performance requirements are determined, the application will be roughly divided into three categories for application requirements:

Less than 150 Dhrystone MIPS: ARM Cortex-M3-based MCUs offer the best price and


From 150 to 500 MIPS: ARM9-based MPU may be the best choice

From 500 to 1,500 MIPS: MPUs based on the Cortex-A8 core are best suited for higher computing requirements

Kernel Subsystem Components:

Application Processors: OMAP multimedia applications processor series with excellent computing performance of these applications is the best choice. In addition, the highly integrated peripheral set also contains many system components, can reduce the cost of the entire BoM and PCB size. Graperain's SmartReflex ™ power and performance management technology reduces power consumption and dynamically controls voltage, frequency, and power based on device activity, operating mode, and temperature.

Single Board Computer:

Single Board Computer (), the shortest possible development time of the android single board computer is off-the-shelf I / O with a compact motherboard; due to its power density, almost always use low-power CPU. Objectives The OMAP35x platform includes the following functions:

The ARM® Cortex ™ -A8 core, which offers four times the performance improvement over ARM9, enables notebook-like performance at the handheld device power level

Based on c64x + DSP-based video subsystem (up to 720 HD resolution)

OpenGL ES 2.0 compatible graphics hardware (up to 100 million polygons per second)

HMI: The practicality of a human-machine interface (HMI) system depends on its processing power, the ability to present complex vivid images, the ability to respond quickly to user input, and the flexibility to handle various levels of operator interaction. Graperain' OMAP devices have the processing power, graphics accelerators and peripherals to meet the increasingly demanding requirements of the HMI world. OMAP with notebook-like performance enables users to implement new features and functions in any HMI without undue cost.

POS: Graperain offers a solution and processor platform for the electronic point-of-service (POS) market with USB 2.0 and EMAC connectivity.

The OMAP-L1x product integrates the 300MHz ARM9 with a 300MHz optional floating-point or fixed-point (total system performance up to 600MHz) and a variety of feature-rich peripheral sets. Maximum standby power consumption is 10mW "500mW operating performance. LCD and video support up to QVGA.

The OMAP35x product has 500mW (typical) operating power consumption and standby power consumption as low as 5mW. Peripheral integration on these products includes EMAC, CAN, USB OTG HS 2.0 PHY, 1.8V / 3.3V IO and LPDDR / DDR2 support.

Connectivity: Connects wirelessly to Bluetooth, WLAN, and 3G networks and is also suitable for industry-standard wired communications such as CAN, UART, USB OTG, I2C, and 10/100 Mbit Ethernet. These interface options allow the system to be connected to a variety of peripherals and accessories, depending on the end application requirements.

Touch-screen controller: Graperain's touch-screen controller provides a low-power, high-performance solution to meet the various needs of touch screen. The controller also provides programmable resolution (8 or 12 bits), control logic for measuring touch pressure, and touch screen measurement preprocessing to reduce bus load, thereby reducing host processor resource consumption so that these resources can be routed to More important features are used.

We can choose any System on Module and a compatible carrier board, to create a Embedded Singe Board Computer that is tuned to your needs.
