ISA總線概述 ISA總線: (Industry Standard Architecture:工業標準體系結構)是IBM公司為PC/AT電腦而制定的總線標準,為16位體系結構,只能支持16位的I/O設備,數據傳輸率大約是16MB/S。也稱為AT標準。開始時PC機面向個人及辦公室,定義了8位的ISA總線結構,對外公開,成為標準(ISO ISA標準)。第三方開發出許多ISA擴充板卡,推動了PC機的發展。1984年推出IBM-PC/AT系統,ISA從8位擴充到16位,地址線從20條擴充到24條。1988年,康柏、HP、NEC等9個廠商協同把ISA擴展到32位,即EISA總線(Extended ISA)。

Decoding most of the infrared signals can be easily handled by PIC16C5X microcontrollers. This application note describes how this decoding may be done. The only mandatory hardware for decoding IR signals is an infrared receiver. The use of two types is described here. Both are modular types used often by the consumer electronics Industry. The first type responds to infrared signals modulated at about 40 kHz. The second responds to non-modulated infrared pulses and has a restricted range. The hardware costs of each approach will be less than two dollars.

The PCI Local bus concept was developed to break the PC data I/O bottleneck and clearly opens the door to increasing system speed and expansion capabilities. The PCI Local bus moves high speed peripherals from the I/O bus and places them closer to the system’s processor bus, providing faster data transfers between the processor and peripherals. The PCI Local bus also addresses the Industry’s need for a bus standard which is not directly dependent on the speed, size and type of system processor. It represents the first microprocessor independent bus offering performance more than adequate for the most demanding applications such as full-motion video.
