Description
Summary:The report comprises 4 main Sections, labeled: (I) General information; (II) Operational characteristics; (III) Special topics; (IV) Logical design. Section (I) describes the theory of operation and the number system employed. It also gives details of the drum memory and the A/C section. Section (II) gives a detailed description of the operations performed during each type of command. It also presents a mathematical or symbolic description of the operation of DREAC in all commands. Section (III) presents special information of the type needed by the programmer. It includes rounding, representation of zero, overflow and the like. Section (IV) is the bulk of the report. It gives in detail the logical equations which describe exactly the modus operandi of DREAC. Explanations accompany the equations. The explanations are aimed at the reader with more than a cursory acquaintance with logical design. (Author)
