Apparatus for computing an arithmetically accumulated sequence of numbers

Abstract

Apparatus for computing an arithmetically accumulated sequence of exponenantissa formatted numbers, which comprises write-in apparatus and read-out apparatus. The write-in apparatus comprises means for separating each of a sequence of numbers in exponent-mantissa form according to the values of the exponent, the value of the exponent being employed as a storing address for the number. Means connected to the separating means algebraically sum mantissas of like exponents; the two above means comprising a write logic block. A random-access memory is connected to the summing means for storing the sum of the mantissas. It also includes means for addressing the storing means. Means are connected between the storing means and the summing means for writing the last stored quantity back into the summing means, so that it may be summed algebraically to the latest incoming mantissa from the sequence of numbers, the new sum then being written back into that part of the random-access memory with the same, like, exponent address. The read-out apparatus is similar to the write-in apparatus.
