进程1 和进程 2 对各自虚拟内存区的修改只能反应到各自对应的物理内存页上,而且各自的修改在进程之间是互不可见的,最重要的一点是这些修改均不会回写到磁盘文件中,这就是私有文件映射的核心特点。 我们可以利用 mmap 私有文件映射这个特点来加载二进制可执行文件的 .text , .data section 到进程虚拟内存空间中的代...
static int load_elf_binary(struct linux_binprm *bprm) { // 将二进制文件中的 .text .data section 私有映射到虚拟内存空间中代码段和数据段中 error = elf_map(bprm->file, load_bias + vaddr, elf_ppnt, elf_prot, elf_flags, total_size); } static int load_aout_binary(struct linux_binprm ...
The following data types are defined through typedef: shmatt_t Unsigned integer used for the number of current attaches that must be able to store values at least as large as a type unsigned short. The shmid_ds structure contains the following members: struct ipc_perm shm_perm /* operation...
The data saved in the FPGA memory is then analyzed, and the results (DI map pixel values) are transmitted to a host computer for visualization via universal asynchronous receiver/transmitter (UART) protocol. The FPGA system architecture is described in detail in the next section. C-clamp is ...

In this setting, methods from conventional SHM [11] can potentially be applied to population data, as demonstrated in the first case study, in Section 3. Importantly, the strongly-homogeneous case represents an idealised population. Returning to the wind farm example, while the population is ...
Data collected from the damaged structure are tested in the trained model. In the top right section of the figure, the observable shift in reconstruction errors effectively highlights the detection of anomalies indicative of damage. The incorporated mechanics knowledge notably enhances the distribution ...
