FILTERING REMOTE DATA SYNCHRONIZATION BARRIER (DSB) INSTRUCTION EXECUTION IN PROCESSOR-BASED DEVICES - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240320160 titled 'FILTERING REMOTE DATA SYNCHRONIZATION BARRIER (DSB) INSTRUCTION EXECUTION IN PROCESSOR-BASED DEVICES
Simplified Explanation: The patent application discusses a method for filtering remote data synchronization barrier (DSB) instruction execution in processor-based devices. In simple terms, it involves determining when a certain instruction is unnecessary to execute, thus improving the efficiency of the processor-based device.
- The processor-based device includes multiple processors such as an issuing processor and a remote processor.
- The remote processor receives instructions from the issuing processor, including a Translation Lookaside Buffer Invalidation (TLBI) instruction and a DSB instruction.
- The remote processor checks if the TLBI instruction meets specific criteria that determine if executing the DSB instruction is unnecessary.
- If the criteria are met, the remote processor skips executing the DSB operation and sends an early acknowledgment to the issuing processor.
Key Features and Innovation:
- Filtering remote data synchronization barrier (DSB) instruction execution in processor-based devices.
- Determining when to skip executing a DSB operation based on specific criteria.
- Improving the efficiency of processor-based devices by avoiding unnecessary instruction execution.
Potential Applications:
- This technology can be applied in various processor-based devices to enhance their performance and efficiency.
- It can be beneficial in systems where data synchronization barriers are frequently used.

Questions about Filtering Remote Data Synchronization Barrier (DSB) Instruction Execution: 1. How does the filtering process of DSB instruction execution improve the efficiency of processor-based devices? 2. What are the specific criteria used to determine when to skip executing a DSB operation based on a TLBI instruction?
Original Abstract Submitted
filtering remote data synchronization barrier (dsb) instruction execution in processor-based devices is disclosed herein. in some exemplary aspects, a processor-based device provides a plurality of processors including an issuing processor and a remote processor. the remote processor receives, from the issuing processor, a translation lookaside buffer (tlb) invalidation (tlbi) instruction indicating a request to invalidate a tlb entry of a plurality of tlb entries of a tlb of the remote processor. the remote processor also receives a dsb instruction from the issuing processor. the remote processor determines whether the tlbi instruction satisfies filtering criteria, which specify conditions under which execution of the dsb instruction by the remote processor is unnecessary. if the remote processor determines that the tlbi instruction satisfies the filtering criteria, the remote processor foregoes execution of a dsb operation corresponding to the dsb instruction, and issues an early dsb acknowledgement to the issuing processor.
