OVERVIEW |
With the increasing number of functions performed by cell phones, processors are faced with demand for advanced multimedia processing capabilities.
Coping with services that are offered by third-generation cell phones, such as videophone and video distribution, is difficult for the CPUs of the base band LSI chips of conventional cell phones.
That points to the need for an application processor to strengthen multimedia processing.
Furthermore, the increased software development work needed to cope with this multifunctionality is also becoming a problem for system development.
Hitachi has developed the SH-Mobile Series RISC microprocessors to strengthen multimedia processing performance and the power conservation function for cell phones with advanced functions.
The SH-Mobile Series answers the needs for advanced system functionality and shorter development time by providing basic cell-phone middleware and an application development platform together with the LSI.
Furthermore, we are expanding the product line-up to cope with diversification of specifications.
