| 术语 | bit-slice architecture |
| 释义 | bit-slice architecture 位片结构;［数元切片结构］ With the discovery that a complete central processing unit CPU could be placed on a single chip, it was found that additional functions (principally, a memory) could be added to form a computer-on-a-chip. However it was also found that certain advantages could be achieved (namely, speed) by partitioning the CPU into slices rather than putting it all on one chip. A typical control section is assembled with several identical 2-and 4-bit slices for the arithmetic and logic unit (ALU) and the registers. The slices are connected in parallel, making it possible to put together units that have several different word lengths. This approach is used to form microprocessors with word lengths ranging from 4 to 32 bits. Bit slice architecture allows the word length to be tailored to the accuracy and precision requirements of scientific calculations. Software architecture allows the users to develop high-speed floatingpoint in structions and function instructions, as required for scientific calculations. Bit-slice architecture usually employs bipolar technology because of the neces- sity for limiting component densities to facilitate the dissipation of heat. 随着可放入单一芯片的整个中央处理单元(CPU)的出现,我们可以使之增加其它的功能(主 要是存储器)而形成单片计算机。然而,我们发现通过把CPU划分成几个位片而不是把整个CPU 放入一个芯片,可带来一些好处(即提高了速度)。一个典型的控制部分可用几个相同的2位或 4位的片子(作为运算部件和寄存器)组装而成。这些位片是并行连接的,使它有可能组装成具 有几种不同字长的部件。使用这种方法来形成字长在4—32位范围内的微处理机。位片结构 允许根据科学计算的精度要求来设计字长。它的软件结构允许用户根据科学计算的需要开发 高速浮点运算指令和函数指令。位片结构通常使用双极技术,因为必须限制元件密度,以利于 散热。 |
