Face / Moving Detection Using Kinect + BeagleBoard-xM

1. OpenCV Demo

http://whatnicklife.blogspot.com/2011/03/kinect-beagleboard-xm.html

Beagleboard xM now works fine with kinect + opencv just need gles demos.

2. Auto Chasing Turtle - Autonomous Control With Kinect and Human Facial Detection

http://kinect.dashhacks.com/beagleboard-xm

This creative and fun hack was brought to us by YouTuber HirotakaSter who managed to create a walking robot with a Kinect head that can recognize human faces and then approach them once they are successfully detected.

3. OpenFrameworks + kinect + Android

The SIProp project's members finissed to make "OpenFrameworks x kinect x Android" Development Environment and to run it on Android(armadillo & beagleboard). Watch demo at

Google Challenges Apple, Netflix, Hulu with Video Rentals Services

Google is about to launch a premium video on demand service to be called “YouTube Store.” Netflix is now larger than Comcast suggests a symbolic “changing of the guard” and movement toward IP-based video-on-demand. YouTube clearly sees an opportunity to diversify revenues and evolve into one of the leaders of the next wave of “TV” (IPTV) or IP-based video delivery.

TI DM6467 Memory Map

TI DM6467 EVM Multi-core Examples (256 MB Total Memory)

Address Range	Size	Description
0x80000000 - 0x877FFFFF	120 MB	Linux
0x87800000 - 0x87FFFFFF	8 MB	CMEM
0x88000000 - 0x8F9FFFFF	122 MB	DDRALGHEAP
0x8FA00000 - 0x8FDFFFFF	4 MB	DDR2 (BIOS, Codecs, Applications)
0x8FE00000 - 0x8FEFFFFF	1 MB	DSPLINK (MEM)
0x8FF00000 - 0x8FF0007F	128 B	DSPLINK (RESET)
0x8FF00080 - 0x8FFFFFFF	< 1 MB	unused

This 256MB of physical DDR2 memory is shared between the ARM and the DSP, i.e. both processors can access all of the DDR2. The physical memory addresses are the same for the ARM and the DSP on DM6467 and range from 0x80000000 to 0x90000000.

Verilog Program Language Interface (PLI) and Verilog Procedural Interface (VPI)

According to "The Principles of Verilog PLI", Programming Language Interface (PLI) is a way to provide Application Program Interface (API) to Verilog HDL. Essentially it is a mechanism to invoke a C function from a Verilog code. The construct which invokes a PLI routine in a Verilog code is usually called a system call. The common system calls built-in to most Verilog simulators are $display, $monitor, $finish etc.

The latest version is PLI 2 or Verilog Procedural Interface (VPI).

The following link shows how to use PLI with VCS:
