Good news as of today, This new serial transfer technology will also be implemented for use with SD Input/Output (SDIO), having the objective of making it possible for the SD bus to be used as the internal bus for embedded systems. Just like every fresh technology nowadays, and according to a source involved with the SD Association of the US, "Specifically, the target is the mobile phone internal bus.".Since the resolution of handhelds' internal cameras keep rising, besides other innovative features, the devices have to handle large data flows that also keep increasing, thus the data rate of the internal bus has to take proportions to keep up the pace. Most products on the market today are using the parallel transfer schemes, but more and more people in the industry fear that the data rate limit is quickly approaching. As there is increasing demand for a unified internal bus technology, adopting the SD bus for the internal bus in 4.00-compliant cards seems like a good idea.
Also, regarding the industry, it seems like another serial transfer technology, namely the mobile industry processor interface (MIPI), supported by Nokia Corp of Finland and others, is planned to receive a boosted data transfer rate, from the current value of about 1Gbps. Ending this article, some sources in the industry point out that SD bus really has a chance of replacing the MIPI.
