本文描述一个高速运算器,该运算器在乘法和除法中都采用“子倍数算法”(sub-multiple algorithm)。文中还介绍了使运算既经济又实用的系统及电路。由于在四个关键性的地方,即在非破坏性读出的隧道二极管存储器,存储选挥驱动器、隧道二极管加法器以及双向移位寄存器中采用了隧道二极管,因而使运算器取得了良好的性能。该运算器对两个44位的操作数执行定点二进制乘法和除法操作,其时间分别为2.75微秒和12微秒。现已制成了一个试验性的运算器并且它已和一架计算机(Honeywell 800)联用。在一个48往的二进制全加器中,罗辑级之间的传输迟延小于2.2毫微秒。本文还讨论了定量实验的某些结果。
This article describes a high-speed calculator that uses a “sub-multiple algorithm” for both multiplication and division. The article also introduced to make computing both economical and practical systems and circuits. The tunneling diode is used in four key areas, tunneling diode drivers, memory select drivers, tunneling diode adders, and bidirectional shift registers for non-destructive readout, giving the operator good performance . The operator performs fixed-point binary multiply and divide operations on two 44-bit operands for 2.75 and 12 microseconds respectively. An experimental calculator has now been made and it has been combined with a computer (Honeywell 800). In a 48-bit binary full adder, the transmission delay between Rowevels is less than 2.2 ns. This article also discusses some of the quantitative results of the experiment.
