SPUR coprocessor interface description

Book ·
OSTI ID:5435704
This report describes the SPUR coprocessor interface. The interface provides enhanced performance potential by allowing parallel operations between the SPUR processor and SPUR coprocessors. A decoupled control and execution architecture allow data transfers to proceed while coprocessor functions are performed. Implicit and explicit synchronization mechanisms provide the programmer with complete control and flexibility. On-chip coprocessor register files and a wide data path between the memory and coprocessor minimize data transfer overhead. An intelligent interface control unit provides parallel decoding of instructions for maximum performance.
