Micro for mobile image and audio processing

23 October 2002 DSP, Micros & Memory

Hitachi's SH300, the third product in its SH-Mobile series of mobile phone oriented application processors, offers dedicated high-speed execution of moving-image and audio processing for data communication based, next-generation mobile phone applications such as video-phones. Features include an MPEG-4 hardware accelerator for image processing which enables high-speed on-chip processing. In previous Hitachi products this was handled by middleware. This reduces CPU processing load to a fifth that of previous SH-Mobile products. The new processor has an SH3-DSP CPU core operating at a frequency of 133 MHz. It has an SXGA camera-compatible interface and also provides a varied selection of middleware for speedy and efficient development of application software.
