增加内存可以直接提高系统的性能,因为直接访问物理内存比访问存储在磁盘上的高速缓存要快得多。
By increasing the RAM storage, you directly increase the performance of the system, because direct accesses to physical memory work much faster than accesses to disk-stored caches.
虽然这是一种泛泛的解释,但至少指出了修改物理内存会“影响其他程序或系统安全,程序一般不需要直接访问物理内存”。
PinyinUp. exe may be malicious. It may be attempting to affect other programs or the security of the system. Programs do not normally need to access physical memory.
当程序尝试使用虚拟地址访问内存时,操作系统结合片上硬件将该虚拟地址映射到物理位置。
When a program tries to access memory using a virtual address, the OS in combination with on-chip hardware maps that virtual address to the physical location.
这些模块提供对内存设备的物理访问,但并不直接使用它们。
These provide physical access to memory devices, and are not used directly.
tlb缓存条目重用(缓存命中)意味着更快的地址转换,还意味着对物理内存的更快的访问。
TLB cache entry reuse (cache hit) equates to quicker address translation and subsequently faster access to physical memory.
物理内存是加快访问的关键。
即使其中每个系统都能访问4gb的内存范围,这并不表示它们各自拥有4gb的物理内存分配。
Even though each one of them is capable of accessing a 4gb range of memory, it doesn't mean that they each get their own 4gb allotment of physical RAM.
这样,每个进程都获得了自己可以使用的地址空间,可以访问比您物理上安装的内存更多的内存。
This way, each process gets its own address space to play in and can access more memory than you have physically installed.
CMP紧密耦合的本质使处理器与内存之间的物理距离很短,因此可提供最小的内存访问延迟和更高的性能。
The tightly-coupled nature of the CMP allows very short physical distances between processors and memory and, therefore, minimal memory access latency and higher performance.
因此,为了获得更大的缓存、平衡和并行访问负载,您应该在远程机器上使用JVM以访问更多的物理内存。
Therefore, to get large caches, and balanced and parallelized access loads, you might want to use JVMs on other remote machines to get access to more physical memory.
访问操作系统提供的内存地址要比读取(物理内存中的)常驻地址慢很多,因为必须硬盘驱动器加载它。
Accessing a memory address that has been swapped is a lot slower than reading a resident (in physical memory) address because it must be loaded from the hard drive.
在内存空间中的内存地址允许代理访问物理ram中的内存。
The memory addresses in the address space allow the agent to access the memories in the physical RAM.
内存管理单位,把虚地址转化为物理地址并且提供访问许可控制。
MMU Memory Management Unit, translates virtual to physical addresses and provides access permission control.
物理地址是用来真正访问内存单元的地址。
Physical addresses are used to address memory cells in memory chips.
物理地址是用来真正访问内存单元的地址。
Physical addresses are used to address memory cells in memory chips.
