摘要： Disclosed is a signed multiplier for use in a data processing system that handles 2's complement operands. The signed multiplier operates to form a preliminary product independently of the signs of the multiplier and multiplicand. While the multiplication is in progress, the signs of the multiplier and multiplicand are checked. For multiplications where either one of the operands (multiplier or multiplicand) is negative, the preliminary product is modified by one or two correction factors. The correction factors are multiples of the 2's complements of the operands. The correction factor or factors are added to the preliminary product to form the final product.

摘要： Disclosed is a control unit including a flexible decoder unit providing control patterns for controlling functional units in data processing equipment. The control unit includes hardwired decoder logic which decodes a multi-bit key to provide primary decoded outputs as control patterns. The decoder unit also decodes one or more alternate decoded outputs for future use. The decoder includes a plurality of flexibility inputs which, when connected to an alternate decoded output, provide new control patterns and thus provides flexibility to the hardwired decoder. Because of the flexibility, the control patterns formed by the hardwired decoder can be readily changed. The flexible hardwired decoder is of great value, therefore, when design changes are desired in a computer.

摘要： Disclosed is a method and apparatus for predicting the condition code of a condition-code-setting instruction by comparing operands in a data processing system. An operand comparator includes one or more half-adders to predict carry outs at an early time. The comparator is used in a data processing system which is operative in response to instructions having operation codes for specifying operations to be executed. The instructions also have operand fields for identifying operands to be utilized in connection with executing the instructions.
