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

Chithra Somasundaran, Sariga p s

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.
