美国得克萨斯仪器公司研制出一种每秒钟能执行一亿个指令的砷镓计算机芯片,比目前大多数主计算机的芯片都更为快速。该出司希望在l989年将芯片的速度增加到每秒钟执行二万个指令的能力,从而达到应用于超大型计算机的水平。这种新型芯片用砷化镓代替了硅,并采用了称之为简化指令系统计算法(RISC)的设计途径。这样,芯片就可以通过内部时钟 Texas Instruments has developed an arsenic germanium computer chip capable of executing 100 million instructions per second, which is faster than most current main computer chips. The company hopes to increase the speed of the chip to execute 20,000 instructions per second in l989, thus reaching the level applicable to supercomputers. The new chip replaces silicon with gallium arsenide and uses a design approach called Reduced Instruction System Computing (RISC). In this way, the chip can pass the internal clock
