Xilinx SDK Drivers API Documentation

Math Engine (ME) Run Time Software (RTS) Driver is a congregation of software based APIs for the PS application to configure/initialize/program the AIE array and shim.The layered software stack of the AIE RTS driver is shown below :

The Driver APIs are typically invoked by the Cardano tool flow as part of the PS application generation. The APIs can also be directly invoked by the user application for performing any runtime configuration like partial reconfiguration etc.
AIE driver is partitioned into the following sub-components :
AIE driver will be common for all the Math Engine devices. So in the similar lines of xparameters.h for other standalone drivers, AIE driver also needs the following device related parameters :
These parameters can be passed to the AIE driver in the similar lines of any other standalone driver i.e., in the form of compile time parameters from xparameters.h or in the form of a runtime configuration object etc.
AIE RTS driver provides a suite of APIs to be invoked by the application layer and also a low level interface abstraction for the driver APIs to interface with the low level target specific APIs. These low level target APIs are in turn used to talk to the underlying target platform with typical AXI read and write transactions.
Following are the features of the AIE RTS driver APIs :
