1.13 Question:
What is Card Bus?
Answer:
CardBus devices combine the best features of 16-bit PC Cards with the performance of 32-bit
PCI adapters. The CardBus specification provides a standard interface for peripherals.
CardBus delivers increased throughput and functionality through 32-bit data transfers, bus
mastering, and other PCI features, while maintaining backward compatibility with 16-bit PC
Card adapters. The following are the CardBus key features:
• True 32-bit I/O with high speed 33MHz bus, compared with an 8.33MHz bus for 16-bit
I/O.
• Bus mastering allows peer-to-peer CardBus data transfers.
• Burst-mode data transfers.
• Low power consumption using 3.3-volt CMOS devices.
• Hot Insertion and automatic configuration.
• Support for 16-bit PC Card and 32-bit CardBus devices in the same slot.
• True processor independence.
1.14 Question :
What is ZV port?
Answer:
ZV Port is the short form of Zoomed Video Port, which is one of the major multimedia data
transports nowadays. ZV Port is also a low cost and compact solution requiring no additional
chips or space on the motherboard. ZV port delivers a high performance video data
transmission rate up to 27Mbytes/sec and supporting full motion/full screen video on a
notebook. This alternative path for multimedia data transfer minimizes CPU utilization and
PCI bus contention since video data is transferred directly to the video and audio system
through a dedicated bus. Also, the only the upper slot of A440 series supports ZV port.
