UnverifiedA DPU (data processing unit) is a programmable dedicated processor, usually deployed inside a server as a separate PCIe card, that takes on network-, storage- and security-related infrastructure tasks.80% similarUnverifiedModern operating systems use the privilege-level mechanism provided by the CPU to divide the execution environment into user mode and kernel mode; user-mode programs run at a restricted privilege level and cannot directly access hardware or arbitrary memory; when they need services such as file read/write, network communication, or process management, they must trap into the kernel via a system call (syscall), and the kernel executes it on their behalf.64% similarUnverifiedThe baseband processor runs independently of the application processor, has its own real-time operating system and direct control over radio frequency hardware, and in many architectures holds higher system privileges than the application processor and can access device memory.60% similarUnverifiedVulkan and DirectX 12 introduced the Command Buffer mechanism, allowing command buffers to be recorded in parallel across multiple threads to reduce CPU-side driver overhead.60% similarUnverified容器依赖Linux的Namespace（资源隔离）和Cgroup（资源配额限制）两大机制，配合Seccomp过滤系统调用59% similar
