Study Notes
PCI Bus Architecture
- Peripheral Component Interconnect (PCI) bus is a local bus standard used to connect hardware components to a computer's motherboard.
PCI Definition
- PCI stands for Peripheral Component Interconnect in the context of computer hardware.
PCI Bus Performance
- Two main factors that influence PCI bus performance are clock speed and bus width.
- The PCI architecture can operate at a clock speed range of 25-33 MHz or 50-66 MHz.
Bus Width and Performance
- Bus width is directly related to PCI bus performance, with a wider bus width allowing for more data transfer.
Systems That Use PCI Architecture
- High-end servers and workstations use PCI architecture for high-speed I/O subsystems.
PCI vs PCIe
- The main difference between the previous PCI card and the successor PCIe card is that PCIe uses a point-to-point connection, whereas PCI uses a shared bus architecture.
PCI-X Bus Technology
- PCI-X bus technology has doubled the clock speed to 133 MHz, allowing transfer speeds up to 1 GB/sec.
PCI Express (PCIe) Purpose
- The main purpose of PCI Express (PCIe) is to provide a high-bandwidth, low-latency, and scalable I/O connection.
PCI and PCI-X Comparison
- A true statement about PCI and PCI-X is that PCI-X is a higher-speed extension of the PCI bus.
PCI-X Slot Width
- The width of a PCI-X slot is 164 pins.
Mandatory Features of PCI-X
- The feature of PCI-X that was made mandatory compared to PCI is the 64-bit data transfer.
Increasing Clock Speed or Bus Width
- Increasing clock speed or bus width allows you to increase the data transfer rate.
Classic PCI Standard
- The PCI card follows the original PCI standard with a classic shared bus architecture.
PCIe Requirement
- The main requirement of PCIe to support higher data rate I/O devices is a point-to-point connection.
PCIe Technology
- PCIe adopts a serial point-to-point connection technology.
