Key arguments
Internal SRAM with 2.5Mbyte capacity
Due to big SRAM - same easy usage as a FLASH device
Booting from a real low cost serial SPI Flash < 0.20€
After boot forget the serial Flash –> work from internal SRAM
After boot a it’s a real one Chip Solution – no external RAM, no NOR, no NAND
Lower BOM and PCB costs
QFP package allows 2 layer PCBs
smaller PCBs due to reduced external components
Smaller failure rates due to reduced external components
Enhanced Graphics performance
enough SRAM for double frame buffers, video buffer and program code
OpenVG 1.1 Vector Graphics Accelelerator – fully compliant to Khronos API
SVGA LCD controller with 3 layers for alpha blending and chroma keying blending
CMOS camera interface for video recording
Others
Good connectivity with USB, CAN and IEBUS
Good family concept w & w/o CAN & IEbus and 2 different memory configurations
Its a lot of SRAM onCHIP BUT its cheaper than expected

Renesas SH2A optimized JPEG library
Very useful for MotionJPEG (MJPEG) animations
MJPEG is commonly known on picture cameras for video recording
JPEG Compression by Base-line Method
Compress & Expand Full Color Data (24-bit/pixel) by about 1/10 to 1/20
Conversion Speed
Compression: About 0.37 Second (SH7261@80MHz)
Expansion:
About 0.28 Second (SH7261@80MHz)
Sampling Ratio: Y : Cb : Cr = 4:1:1
VGA(640dots x 480dots x 3): About 460,000 Pixels
Compact Size
Encode: ROM about 4.4KB / RAM about 1.2KB
Decode: ROM about 4.4KB / RAM about 4.7KB
SH2A CPU could be used for MJPEG en- and decoding
compress video stream from external camera to allow proper storage
playback of MJPEG video from other sources
