On-chip bus structure for custom core logic designs

The open standard PLB, OPB and DCR buses provide the primary means of communication between macros in an IBM custom core logic design. Designers realize several advantages in creating and using compliant macros. First, IBM is continually expanding its extensive library of Blue Logic off-the-shelf core macros. These logic blocks are easily integrated into a customer's SOC solution. Additionally, customers benefit by being able to reuse their own macros in multiple products. Finally, these common interfaces allow for easy integration, providing valuable time savings when implementing complex designs.
