SDK Workflow

This workflow illustrates how SDK manages an offloading process to the XCENA accelerator.

1. Prepare Offloading

• Build a Compute Kernel from source code of Offloading Application.
• Define and optimize specific computational tasks for accelerator execution.

2. Build Host Application

• Prepared Compute Kernel is loaded into the Host Application.
• Host Application interacts with Runtime Library through API calls, setting up and controlling the necessary resources.
• Runtime Library allocates CXL Memory and manages the Processor for executing the data processing tasks.

3. Offloading

• Host Application accesses CXL Memory to input the necessary data for processing.
• Execute the Compute Kernel on the Processor using data stored in CXL Memory.
