Summary¶
This library provides access to hardware and software locks for use in concurrent C programs. However, it is generally not safe to use these for marshaling within XC, due to the assumptions XC makes about safe concurrent data access.
Features¶
Hardware locks: fast and power efficient but there are a limited number per tile
Software locks: slower but an unlimited number can be used
Intertile lock (xcore.ai only): single lock available for guarding chip-wide access to resources
Known issues¶
Intertile lock uses a MIPI D-PHY register and so cannot be used when MIPI D-PHY is enabled
Intertile lock requires that both tiles are running at the same core frequency. Clocking down one tile may very rarely result in unreliable locking.
