According to In-Stat, non-proprietary I/O is having an increased presence within the central processing, printed circuit board, and IP communities. HyperTransport, PCI Express, and Serial RapidIO have all announced major revisions to their existing standards. All three standards are finding ways to facilitate higher frequency signals and, as such, will have greater per-link chip-to-chip throughputs and higher overall bandwidths.
In-Stat beleives the increased bandwidths serve to make the I/O more purposeful. However, the non-proprietary I/O (or standard I/O) is stretching out to new usages. Early adopters of the new standards are expected to be computing, networking, and communications.
In-Stat found the following in their research:
- Non-proprietary I/Os were in 461.3 million devices in 2006.
- By 2010, there will be 517.3 million devices with non-proprietary I/Os.
- PCI Express, a serial I/O instead of a parallel I/O, has changed the nature of the PCI bus.
The research, I/O, I/O, Changing the Status Quo: Chip-to-Chip Interconnects, covers the implications of changes in the I/O, and what they mean on a device level. For example, the I/O requirements are different for portable devices than for personal computers. The usages of HyperTransport, PCI Express, and RapidIO are forecast for devices from 2004-2010.
