Review PCI Express, SATA II and Silicon image 3132 (SI3132) Introduction PCI Express (Bus Type, Clock Frequency, Peak Bandwidth, Slots per Bus) and SATA II; Silicon image 3132, PCI Express Aggregate Throughpu, Some system PCI express in PC. | Review PCI Express, SATA II and Silicon image 3132 (SI3132) • Introduction PCI Express and SATA II • Silicon image 3132 Engineer: HOA HOANG Introduction PCI express • PCI Express is the third generation high performance I/O bus used to interconnect peripheral devices in applications. The first generation buses include the ISA, EISA, VESA, and Micro Channel buses, second generation buses include PCI, AGP, and PCI-X.

Comparison of Bus Frequency, Bandwidth and Number of Slots Introduction PCI express PCI Express Aggregate Throughput A PCI Express interconnect that connects two devices together is referred to as a Link. A Link consists of either x1, x2, x4, x8, x12, x16 or x32 signal pairs in each direction. These signals are referred to as Lanes. Aggregate bandwith numbers in Table 1-3 multiply Gbits/sec by 2 (for each direction) PCI Express Link Width Aggregate .
