MX8870
Comparison with other LSI
- MX8870 (DSC-2) supports max 4000 x 4000 pixel, and RGB bayer, RGB stripe, Complementary color filter array, and Progressive or Interlace type CCD. - Support both 16-bit and 32-bit SDRAM bus. --> Only one 1Mb x 16 SDRAM required for progressive sensors. - Embedded 3 PLL --> Only one external crystal required for TV, USB, and CPU.
Main Functions
Monitor mode Monitoring speed is same as CCD readout rate. Monitor image processing (interpolation, Edge Enhancement, Color space conversion, Resolution translate) is done by H/W. (If CCD read rate is 30-fps, monitoring speed is 30fps). Capturing mode Processing speed is just 0.16-Sec for 3M CCD, excluding read out time and card writing time. This operation speed includes JPEG encode and interpolation, Edge Enhancement, Color Space Conversing, Re-sizing. Display mode Display speed is only 0.2-Sec for 3M pixel image excluding card reading time. This operation speed includes JPEG decode and Color space conversion, Recision.
Real-time Processing Unit(RPU) Function
RPU has following functions. - Monitoring operation is same as CCD readout rate. - Real Time capturers operation : For progressive CCD, all processing including JPEG encode is completed at just after the end of CCD readout. - Post processing operation : After capturing the full-frame raw data, RPU can process the Interpolation, Edge Enhancement, Color Space Conversion, Re-sizing, etc. much faster than CPU operations. This operation can extend the filter size for Edge Enhancement. And also many kinds of adaptive and nonlinear processing is avaliable with RPU in very shot time. - Improvement of the Signal to Noise ratio : There is a special circuit for improvement of Signal to Noise ratio at the multiple frames image capturing.
Real Time OS
DSC-2 supports following OS : micro ITRON and Nucleus+
