占据统治地位的台式计算技术——X86 PC结构正大举抢进嵌入系统市场.PC兼容主机板、组件甚至单片系统正在广大系统领域里向历史悠久的微控制器和大功率处理器发起挑战.许多设备制造商转向PC技术,旨在协调到处可得的硬件和庞大的PC软件支持.这一趋向在计算机和电话技术正在合流的通信领域尤为强劲.美国Embedded Systems Research公司日前发布的一份《1995 EmbeddedSystem Survey Report》(1995年嵌入系统调查报告)说,当前20%的嵌入系统设计采用了某种形式的PC ISA一总线结构.报告预计,2年内这一比例将提高到34%,大多数都是用来取代单片微控制器和处理器的传统专有设计.由于是仅作了ISA总线的比较,因而实际上比例还会更高一些.
The dominant desktop computing technology, the X86 PC architecture, is gaining traction in the embedded system market, PC-compatible motherboards, components and even monolithic systems are challenging the long-standing microcontroller and power processor in a broad range of systems. Many device makers are turning to PC technology to coordinate the availability of hardware and large PC software support, a trend that is particularly strong in communications where computer and telephony technologies are converging. Embedded Systems Research Inc. of the United States recently released a " According to the 1995 Embedded Systems Survey Report, currently some 20 percent of embedded system designs use some form of PC ISA-bus architecture and the report expects this to increase to 34 percent in two years, with most Are used to replace the traditional proprietary design of single-chip microcontrollers and processors, which is actually much higher due to the ISA bus-only comparisons.
