Processing Memory Access Transactions

A non-transitory computer-readable storage medium having computer code stored thereon, which when run on a processing system, causes the processing system to process a memory access transaction through an execution path of the processing system, wherein a memory attribute structure comprises one or more memory address entries, each memory address entry comprising a respective memory address range mapped to a respective priority level of a set of priority levels, and wherein said processing a memory access transaction comprises:

• determining a memory address of the memory access transaction;
• using the memory attribute structure to determine a priority level mapped to the determined memory address;
• and
• processing the memory access transaction based on the determined priority level.

A processing system for processing a memory access transaction through an execution path of the processing system, wherein the processing system has stored, in memory, a memory attribute structure comprising one or more memory address entries, each memory address entry comprising a respective memory address range mapped to a respective priority level of a set of priority levels, the processing system being configured to:

• determine a memory address of the memory access transaction;
• use the memory attribute structure to determine a priority level mapped to the determined memory address;
• and
• process the memory access transaction based on the determined priority level.
