Latest Patents

One of Tsay's latest patents is titled "Consistent speculation of pointer authentication." This invention involves a processor that includes hardware circuitry designed to authenticate instruction operands. The processor executes instructions that perform operand authentication both speculatively and non-speculatively. During speculative execution, the processor ensures that no observable state differences, relative to authentication results, are detectable via a side channel. The result of authentication may be deferred until the speculative execution of the instruction and additional instructions are completed. Upon resolution of a condition indicating acceptance of the speculative execution, a speculative execution result may cause a processor exception and stall execution at the instruction to be performed.

Another notable patent is "DSB operation with excluded region." This invention relates to data synchronization barrier operations. In this system, a first processor receives a data barrier operation request from a second processor. Upon receiving this request, the first processor ensures that outstanding load/store operations directed to addresses outside of an exclusion region have been completed. The first processor can respond to the second processor that the data barrier operation request is complete, even if some load/store operations directed to addresses within the exclusion region are still outstanding.
