DLPC350 image load question

Other Parts Discussed in Thread: DLPC350

As I understand it you can load images three ways. Through the RGB or FPF link interfaces. Or directly through splash screen flash memory.

And the Flash memory can be loaded directly through USB. Is that correct? We have a limited number of structured light images  ( > 30) we want load and sequence out to the DMD. We are trying to understand the most efficient way to do this and minimize hardware interfaces to do it. USB directly into the chip is preferable way. We have used the 4100 DLP chipset. This seems much easier to get data into the DMD. We would prefer not to use RGB or FPD link interfaces which require more chips in front of the DLPC350.

    Christopher,

    Yes, that is correct. DLPC350 takes as input video source (RGB or FPD-link) or from splash memory residing in external flash.

    The flash memory can be loaded through USB or I2C. The DLPC350 can address up to 32MB of flash memory. The upper 2MB of flash memory is reserved for the DLPC350 firmware.  Thus, the DLPC350 supports up to 64 splash images in up to 30MB of external flash. Since an 8-bit image  can consume 1MB of storage, the DPC350 offers the ability to read RLE compressed images while loading from splash. The total amount of images that will fit in the flash memory will depend on how well they compress.
