| for DLP® Discovery™ Chipsets | ||||||||||||||||||||||||||||||
| The ALP Controller Suite, developed and produced by ViALUX, gives the user access to the full performance of the DLP® Discovery™ chipsets without the need of time consuming developments for hardware, firmware and high-frequency FPGA logic code. ALP Controllers offer flexible tools for programming DLP® operations from PC and they are available for both, DLP® Starter Kit Boards and DLP® Serial Production Boards. The customer can migrate from the Starter Kit environment to the V4100 ViALUX production platform without any additional programming efforts. | ||||||||||||||||||||||||||||||

The outstanding switching speed of the DLP® Discovery™ DMD is supported to its full extend
enabling 22 272 XGA full array switches per second. The user can operate with binary and gray value
patterns, respectively.
The ALP Controller Suite implements a fast and reliable USB2.0 PC interface with enhanced effective transfer rate by lossless on-the-flight compression of data. Data rates up to 1.2 Gbit ⁄ s are achieved that corresponds to 1 600 XGA frames per second. The ALP-4 driver is robust, validated, UIF compliant and well suited for industrial use. Microsoft Windows operating systems are supported up to Windows 7 both, x32 and x64. ALP Controllers support all DMD formats of the DLP® Discovery™ Starter Kit Boards of all platforms and, in particular the most powerful current Discovery™ 4100 systems. A well organized and easy to use application programming interface (API) is provided for programming the DLP® System conveniently. The API library (DLL) is portable and can be used in C++, VBasic, .NET, LabView, and MATLAB. Multiple USB ALP devices may run at the same time and they can be controlled from the same application program. ALP Controllers are upwards compatible enabling smooth migration to the next higher platform. |

|
Sequences of patterns are generated in the PC and uploaded to the on-board memory (32 Gbit SDRAM)
via compressed USB2.0 transfer. Optimized FPGA logic code guarantees precise, triggered transfer of SDRAM data
to the DMD array with 24 Gbit ⁄ s data rate. An Image Scrolling option has been added for all
cases where the projection is aiming at a moving screen (substrate) as it is typical in all types of direct imaging.
The ALP Controller provides high flexibility by free choice of properties of the sequence (bit depth, picture time, trigger control, repetitions). In this way, the pattern sequences can be customized to meet the respective application requirements. An additional I²C interface is implemented to control and monitor LED light sources in connection with the DMD operation. The ViALUX HLD high-power LED driver is addressed via the ALP-4 application programming interface. It allows to adjust the brightness and to read the LED junction temperature for thermal management. ViALUX offers two ALP-4 models, high-speed and basic. The high-speed controller enables maximum switching rates under full-array global shutter operation, gray value patterns and precise triggering while the basic model provides the full flexibility of single line operations. The specification for both models are given in the table below. |

The ALP-3 Controller Suite is a ViALUX hard- and software product developed for the DLP® Discovery™ 3000 Starter Kits of Texas Instruments.
A USB2.0 interface board is added to the DLP® Starter Kit board to implement the PC interface. The ALP operation is based upon this USB2.0 transfer between PC and DLP® System where data are buffered in the on-board memory. There are two models available, the ALP-3 high-speed and basic, both make use of the same ALP-3 USB Board. |
