M-Systems and Renesas will work together on mobile handsets
M-Systems and Renesas
Technology extended their partnership in the multimedia handset architecture field. The companies are to port M-Systems´ Mobile DiskOnChip onto Solution Engine for SH-Mobile processors developed by Hitachi and Mitsubishi Electric.
Besides, in a separate note they state that Renesas Technology invited M-Systems to join the SH-Mobile Consortium, dedicated to timely implementation of SH-Mobile processors and solutions like Mobile DiskOnChip into new-generation handsets.
If you remember, Mobile DiskOnChip is an integrated high-density NAND Flash drive with MLC architecture. It´s primarily designed for multimedia portables.
An SH-Mobile is actually a dual-processor structure. One is dedicated to applications, while another is used for communication needs. It bases on SuperH 32-bit RISC architecture and provides JPEG, MP3 support for handsets, features an AMR codec, is capable of MPEG4 encoding/decoding, etc. At the moment the family includes three processor kinds: SH-Mobile 1 (HD6417290BP133 and HD6417290BL133), SH-Mobile J (HD6417294BP120) and SH-Mobile V (HD6417300BL133).
An example of SH-Mobile-V-based system:
- SH3-DSP core
- 1.4~1.6 V internal voltage, 2.7~3.6 V external voltage
- 133MHz clock rate
- 173 MIPS performance
- 128KB RAM
- 32KB cache
- 16KB DSP memory
- MPEG4 accelerator
- SXGA camera support
- Interfaces
- Dedicated
- NAND/AND Flash
- SDRAM
- Video I/O (direct camera connection)
- Audio
- SIM card
- I2C
- 1 x serial comm
- 1 x serial comm FIFO
- 256-pin CSP (11x11x1.4mm) package
