Design and implementation of Deadlock Avoidance for On Chip Buses with Elastic Buffer and Error Correction

Abstract

Advanced extensible interface protocol and open core protocol are protocols used for on chip communication it can support advanced transactions and it also improve communication efficiency. Out-of-order transactions are return responses in an order different from requested ones. Here we discuss a concept it can support out of order transactions. A graphical model used in the system known as bus status graph used to identify the occurrence of dead lock condition. According to this graphical model we propose a technique it can avoid this deadlock problem. And also using an error detection and correction method to avoid the mismatches in read and write operation between master and slave.
