PCI (Peripheral Component Interconnect) Andrew P. Michelle S. Caleb D. Jon P.
Overview • History • Why is it popular/why do we use it • PCI • PCI-X • PCI-X 2.0 • PCIe
HISTORY • Designed by Intel • Adopted in mid 1990s by Macintosh and PCs • Immediately put into servers, replacing MCA and EISA
Why is it popular/why do we use it? • Better system performance for I/O • Few chips • Supports other buses on the PCI bus • Supports 32 or 64 bit bus • Supported by a large amount of processers and peripherals
Organization of the PCI • Communicates through the PCI bus on the South Bridge. • 49 mandatory signal lines, and 51 optional signal lines. • Data is transferred between an initiator or master and a target. • There are many commands the master can give a target such as I/O Read, I/O Write, Memory Read, Memory Read Line, Memory Write, and Configuration Read.
PCI • Normal PCs • Peak transfer rate of 133 MB/s • Normally 32 bit bus width • Could have 64 bit bus width • Full SIZE= Height of 107 mm (4.2 inches) and a depth of 312 mm (12.283 inches)
PCI-X • Used in servers • Backward compatible with PCI • Has been replaced by PCIe • Frequency up to 133 MHz • Uses parallel technology
PCI-X 2.0 • Adds 266-MHz AND 533MHz • Yielding roughly 2.15 GB/s and 4.3 GB/s • Being replaced by PCIe • Adds error correcting codes • Uses parallel technology
PCIe • PCIe was created in 2004 • Uses serial technology instead of parallel • Use different connectors • Much faster than PCI
