Express Logic, Inc. (San Diego, CA) and Renesas Technology America, Inc. (San Jose, CA) have teamed up to offer a comprehensive reference design platform for powerful, inexpensive media players. The media player platform is based on Renesas' 200-MHz SuperH SH-2A microcontroller architecture and Express Logic's ThreadX® RTOS, and enables access and display of media from USB flash drives or SD memory cards. The reference design features a 640x480 VGA display and application software that enables touch screen user interface, image display, and audio file play. Also featured is the ability to display and play PC-compatible image files (.jpg, .bmp) and audio files (.mp3, .wav, .wma, .aac, .ogg). The reference design is aimed at system developers, providing them with a starting point for their products that saves significant time and greatly assists in timely project completion and faster time to market.

All software components are available through royalty-free licenses, which means that none of the software adds to bill-of-material cost. The device's application code is designed to use its floating-point unit (FPU) and on-chip RAM for audio processing, while displaying images from a USB hosted memory stick or SD memory card on a VGA TFT LCD using its on-chip LCD controller. Peripheral drivers and a board support package are available as part of the reference design.
