Abstract: The present disclosure describes techniques and apparatuses for a hardware-implemented Adelson-Velskii and Landis' (AVL) tree module. In some aspects, commands are received at the AVL tree module that request operations be performed for an AVL tree table stored in memory. Each command is written to one of multiple hardware threads of the AVL tree module that perform AVL tree operations by causing records of the AVL tree table to be read from memory using a single read operation and then written to the AVL tree module, modifying those records without accessing memory, and causing modified records to be written back to memory using a single write operation. Once a command is written to a hardware thread, the hardware thread can perform the corresponding AVL tree operation. After the AVL tree operation is performed, results are returned to the requesting agent to indicate whether the AVL tree operation was performed successfully.

Abstract: The present disclosure describes techniques and apparatuses for hardware-implemented AVL tree updates. In some aspects, records are accessed as part of a search performed to update an AVL tree. The update may involve inserting a new node into, or removing a node from, the AVL tree. The AVL tree is represented by records stored in memory, each of which represents a node of the AVL tree. During the search, each of the records accessed is read from memory. The records read from memory are then written to an AVL tree rebalancing component implemented in hardware. Once the records are written to the hardware-implemented AVL tree rebalancer, it can modify, without subsequently accessing the memory, those records corresponding to the nodes affected by the update. After those records are modified by the hardware-implemented AVL tree rebalancer, the modified records are written back to the memory effective to update the AVL tree.
