TRW 和Motorola 公司最近成功地开发了一种称为算术扩展超级芯片(Atrihmetic Extended Superchip)的中央处理器,它含有大约400万个0.5微米的CMOS 器件,每秒能执行2亿次浮点操作。这样的处理能力使这种重量仅43克的芯片达到了超级计算机的水平。象该芯片这样的体积和密度.往往会带来较高的故障率.但是,这种Super Chip 具有“修理”自身出错部分的能力.Super Chip 与一个作为“卫星”芯片的TRW-Moto-rola 通用处理器(UP)一起使用,UP 对Super Chip进行初始配置、检测和运行期间的监控.Super Chip 自修理的能力来源于它的模块性.它由本质上是处理器积木块的“宏单元”构成.它具有142个这样的宏单元。但完成
TRW and Motorola recently succeeded in developing a central processing unit called the Atrihmetic Extended Superchip, which contains about 4 million 0.5-micron CMOS devices that perform 200 million floating-point operations per second. This processing power has brought the 43-gigabyte chip to the supercomputer level. The size and density of the chip, which often leads to higher failure rates, but the Super Chip has the ability to “fix” its own faults.SuperChip and a “satellite” chip TRW-Moto-rola UP, the UP monitors the Super Chip during its initial configuration, monitoring, and operation.The ability of a Super Chip to self-repair comes from its modularity and consists of a “macrocell ”It has 142 such macrocells.
