WPAR is a reference board of wireless multimedia receiver, aiming to be an application development platform for wireless transmission of audio, image, and video contents.
It is equipped with Renesas SH7751R that works at 240MHz, which allows developers to take full advantage of fast and stable SH-Linux technologies.
A wireless network interface conformed with IEEE 802.11b is connected to WPAR via PC card slot, allowing for keeping up with the latest wireless LAN standards such as IEEE 802.11a and IEEE 802.11g by upgrading the network card.
WPAR's outstanding graphics capability is realized with two controller chips: Silicon Motion's SM501 for 2D image rendering, and VWeb's VW2010 for audio and video decoding. SM501 has several video layers including two graphics layers, two alpha layers, and a video layer, which are utilized for smooth display of image sequences with double buffering, and for building window GUIs. VW2010 supports a number of audio and video formats such as MPEG-1/2/4, their audio layers, AC3, and so forth. The decoded video is simultaneously outputted as VGA and NTSC formats. In addition, VW2010 also has multiple video layers, which enables overlaying of captions and images on moving pictures. This powerful combination of graphics chips releases the CPU from video processing loads and allow it to run interactive tasks during video playing.
Finally, all these features are implemented with selected components in terms of power consumption and thermal emission. As a result, WPAR does not require cooling fans, thus, is the best solution for embedded applications.
