A technical analysis compares Microsoft's Prism binary translator, which lets x86-64 Windows software run on Arm-based aarch64 processors, against native Geekbench 7 performance. Using a pro key from Primate Labs founder John Poole to profile individual workloads, the tester measures how much performance is lost when translating x86-64 instructions instead of running aarch64 code directly.
At Hot Chips 2026, IBM revealed a next-generation processor built on a 2nm node with 11 cores, each running at a 5.7 GHz base clock. The chip's key innovation is a core that can natively execute both z/Architecture and AArch64 instructions, switching between them within nanoseconds, a result of IBM's April partnership with Arm.
Proofcraft has implemented and formally verified a new domain scheduling API for the seL4 microkernel, removing the requirement for a single fixed, compiled-in schedule to maintain information flow security proofs. The API lets systems load semi-static domain schedules that can change across runtime phases, such as longer time slices during boot and shorter ones during normal operation. This capability is now included and proven in seL4 15.0.0.
