Mention the characteristics of PCI bus.

The characteristics of PCI bus system:

(i)  Coupling of the processor and expansion bus by means of a bridge.

(ii) 32-bit standard bus width with a maximum transfer rate of 133 Mbytes/s expansion to 64 bits with a maximum transfer rate of 266 Mbytes/s.

(iii)Supporting of multi-processor system.

(iv)Supporting of 5v and 3.3v power supplies.

(v)Write posting and read perfecting.

(vi)Multi Mate capabilities.

(vii)  Multiplexing of address and data bus reducing the number of pins.

(viii) Supporting of ISA / EISA / MCA.

(ix) Configuration through software and register.

(x) Processor independent specification.
