life, the automatic calibration mode (autolearn modes) is enabled by default. During the learn cycle, the RAID card controller does not enable the BBU until it completes the calibration. The entire process may take up to 12 hours. In this process, the writeback mode is disabled to ensure data integrity while causing performance degradation. The entire learn cycle is divided into three steps: The

Cyclone III FPGAs-50-Ohm on-chip termination (OCT) without calibration for all non-voltage reference and HSTL/SSTL; Class I/O standkehout calibration for HSTL/SSTL; class ii I/O standards-maximum setting for 3.3-V lvttl/lvcmos I/O standards. When a higher fmax is required for the output and timing violation

Image processing--image and its expression and properties

resolutionSpatial resolution (spatial resolution): determined by the proximity between image sampling points on the image plane. Spectral resolution (spectral resolution): determined by the sensor's light frequency bandwidth. Radiometric Measurement Resolution (radiometric resolution): Corresponds to the number of distinguishable gray levels. Time resolution: Depends on the image acquisition time sampling

Fundamentals of DSP Data operation

=8195Binary number 1111111111111100b=-4For a DSP chip, the number of participating numeric operations is the integer number of 16 bits. In many cases, however, the numbers in the counting process are not necessarily integers. So, how does the DSP chip deal with decimals? It should be said that the DSP chip itself is powerless. So is it that the DSP chip can not handle a variety of decimals it? Of course not. The key to this is that the programmer determines which of the 16 digits the decimal poi

After many years, the interest in electronic production began to rise again, so the MCU was replayed. It is enough to make use of hundreds of RVs, tiny13, 2313, and ipv8. But with a single-chip microcompu

Here we use the AR tool to calculate the camera and lens characteristics and g

Tslib steps and solutions to problems

The touch screen is widely used in embedded devices, but the coordinates of the touchscreen and the coordinates of the screen are asymmetrical and need to be calibrated. Calibration is widely used by open source tslib.Tslib is an open source program that provides touch-screen driven sampling with functions such as filtering, dithering, and calibration, often as a touchscreen-driven adaptation layer, providi

At the same time, the driver will turn on a hardware timer, as long as it detects that the touch pen is still pressed, it will trigger the same event to notify the worker thread to collect data, until the touch pen is lifted and the timer is disabled, and re-detect the press status. The Touch Screen interrupt and timer interrupt are used in the driver, which can not only monitor the touch pen press and lift sta

consumption is greater. For example, the increase in the frequency and voltage in audio/video playback will make the power usage grow linearly, dynamic power consumption is also the main problem to be solved in power management. There are several ways to solve dynamic power consumption, such as the development of DPM projects by IBM and montavista (currently used in the mengavista mobilinux 5.0 product) and Linux Power Management of Ti omap3430.

When observing the display in a standing posture, the image quality will be greatly reduced. Fortunately, you can fix the pro
