The following experiment was conducted with a computer and such a chip set.
The PC, which was equipped with an internal 1394b interface, was expanded by four additional standard and economical 1394b cards in 64-bit technology and PCI Express technology.
Three AVT PIKE cameras, a SONY XCD-V50 plus an AVT GUPPY were connected to it. All cameras were parameterized to a maximum data rate. The cameras then generated the data rates shown in Chart 2.
In total, this equals 240 Mbytes/s of data flow from all five cameras.
The computer proved to have no difficulty writing this data volume into the main memory via DMA. Only 15 percent of its computing capacity was required for this.
