SYSTEM, APPARATUS AND METHOD FOR FINE-GRAIN ADDRESS SPACE SELECTION IN A PROCESSOR - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240345841 titled 'SYSTEM, APPARATUS AND METHOD FOR FINE-GRAIN ADDRESS SPACE SELECTION IN A PROCESSOR
The abstract describes a processor with a first configuration register storing a pointer to a process address space identifier (PASID) table, and an execution circuit coupled to the register. The execution circuit, in response to an instruction, obtains command data, a PASID table handle, accesses the PASID table, inserts a PASID value, and sends the data to a device.
- Processor with a first configuration register storing a pointer to a PASID table
- Execution circuit that processes instructions by obtaining and manipulating command data
- Accesses PASID table to retrieve PASID value and inserts it into the command data
- Sends the modified command data to a device for further processing
Potential Applications: - Data processing systems - Virtual memory management - Secure data transfer protocols

Original Abstract Submitted
in one embodiment, a processor comprises: a first configuration register to store a pointer to a process address space identifier (pasid) table; and an execution circuit coupled to the first configuration register. the execution circuit, in response to a first instruction, is to obtain command data from a first location identified in a source operand of the first instruction, obtain a pasid table handle from the command data, access a first entry of the pasid table using the pointer from the first configuration register and the pasid table handle to obtain a pasid value, insert the pasid value into the command data, and send the command data to a device coupled to the processor. other embodiments are described and claimed.
