For Intel VIED (Video and Imaging Engineering Design, previously known as Silicon Hive) work has been done on setting up a test environment for the validation of camera subsystem firmware.The work consisted of two parts:1. Design, implementation and testing of a Linux camera driver for the ISP subsystem.a. For controlling the camera subsystem (Image Signal Processor integrated on an Intel system-on-chip) a Linux kernel driver has been written that made it possible to implement various high-level camera use cases. In addition, the camera driver was controlled via a test application in Android.2. Setting up a test environment where images from an algorithmic model and generated images from the ISP subsystem could be compared and evaluated.a. To test the various processing steps within the ISP (including input formatting, standardization, de-noising, shading correction, white-balancing, de-mosaicicing, RGB correction, YUV processing, output formatting) a test environment has been set up in which image data is extracted the different sub-steps of the ISP could be compared with image data obtained from an algorithmic model (i.e. the basis for the hardware synthesis). The image data obtained from both sub-steps could then be evaluated automatically (with bit-exactness) or visually.Tools : Ubuntu 12.04 LTS, Android 4.3 (Jelly Bean), Linux, C, GCC, Python, Git, Gerrit, Bayer RGB, YUV, Algorithm Testing Environment (ATE), Klocwork, Scrum, Rational Team Concert

For ASML (Metrology) work on the development & integration of product variance control software (BaseLiner™) on various TWINSCAN releases (NXE, NXT and XT) was performed. The tasks involved the design, implementation and testing (SIA-2, TPS, TAR) of proposed software changes, as well as specifying and documenting the impact of proposed changes (SIA-1) on the current software stack running on the TWINSCAN scanner (mainly within the metrology software layer).Tools : Unix (Solaris)/Linux, C, Matlab, Python, UML , Rational ClearQuest & ClearCase, CodeCollaborator, TICS, QAC, CodeSonar, BullsEye.

1. Integration of LifeVibes™ audio enhancement algorithms on the PNX0161 USB headset. For a USB Headset (PNX0161) demonstration on the World Mobile Congress 2009 in Barcelona, the real-time software stack was modified to include several LifeVibes audio enhancement algorithm’s. Next to the integration of the audio libraries an LCD driver was written to provide the listener with feedback on the active algoritm.Tools: I2C, USB-protocol, ARM7, proprietary RTOS, Linux, C, ARM compiler, RealView ICE, JTAG debugger, Subversion, MS Windows XP (Host platform).2. Verification & Validation of digital IP on the PNX0151 Mobile Audio Processor.The PNX0151 Mobile Audio Processor is an co-processor (ARM9 based) optimized for low-power, high quality audio decoding use-cases. To verify the SoC Digital IP (ARM, timer, SDMA, IRAM, IROM, SDRAM, interrupt controller, etc.), low-level unit & integration tests were designed and implemented. A test framework was created whereby each test could be configured to run individually or grouped as needed. The chip was characterized by conduction the tests over different ranges of temperature and voltage.Tools: ARM9, C, Linux, ARM compiler, RealView ICE, GNU development tools, GCC (cross) compiler, SDE2, Logic analyzer, Oscilloscope, JTAG debugger, Subversion, CUnit, Thermal Streamer.

1. Design and Implementation of Embedded Software for a Mobile Multimedia Co-Processor.The PNX4103 project was aimed at creating a component based software stack to support several multimedia use-cases (e.g. audio playback, video playback and camera preview/record). Components are created and controlled by software running on a remote client processor. The PNX4103 embedded software was developed on multiple sites. This model involved regular visits to and from the remote sites as well as regular conference calls to track development progress. All software deliverables were integrated into a software baseline at the Nijmegen site. My responsibility was to define the in- and external interfaces of the components related to video and audio processing as well as implementing the top level software layer in this column of software layers. After integration my responsibility shifted more towards analyzing and solving problem reports in the audio and video codec software stack. External developers were supported on the use of the PNX4103 software when it was used in use-cases serving as a demonstration of the processors capabilities.
