Abstract
A data processing system including a first processor that performs fixed point arithmetic operations and a second processor that performs floating point arithmetic operations. These two processors are connected by control circuitry that decodes a floating point arithmetic instruction that requires the second processor to perform a specified floating point arithmetic operation. The control circuitry provides information to the first processor to enable the first processor to compute a memory address for accessing the floating point data required by the second processor for performing the specified floating point arithmetic operation. Simultaneously the control circuitry provides the second processor with the information to initiate the execution of the specified floating point arithmetic operation. Also, the data processing system includes the means to access multi-word floating point data on either even or odd memory address boundaries.
