ISA总线概述 ISA总线: (Industry Standard Architecture:工业标准体系结构）是IBM公司为PC/AT电脑而制定的总线标准，为16位体系结构，只能支持16位的I/O设备，数据传输率大约是16MB/S。也称为AT标准。开始时PC机面向个人及办公室，定义了8位的ISA总线结构，对外公开，成为标准（ISO ISA标准）。第三方开发出许多ISA扩充板卡，推动了PC机的发展。1984年推出IBM-PC/AT系统，ISA从8位扩充到16位，地址线从20条扩充到24条。1988年，康柏、HP、NEC等9个厂商协同把ISA扩展到32位，即EISA总线(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.
