ISA Bus And PCI Bus
Core Technical Specifications 945GV ISA Bus (Industry Standard Architecture) Data Width & Speed: 16-bit data bus operating at 8MHz, with a maximum theoretical bandwidth of 16 MB/s25. Resource Handling: Relies on CPU for data transfer control, causing high CPU utilization and frequent interrupt conflicts6. Physical Slot: Characterized by long black connectors (~13cm), typically positioned near the motherboard’s bottom edge56. PCI Bus (Peripheral Component Interconnect) Data Width & Speed: Supports 32-bit/64-bit data width at 33MHz, delivering up to 133 MB/s bandwidth (32-bit variant)45. Resource Management: Uses an independent bus controller to reduce CPU load, enabling hot-swapping and interrupt sharing45. Physical Slot: Shorter white connectors (~8.5cm), vis...
