However, the use of current write combining techniques suffer from a number of drawbacks. When there are a number of concurrent operations, it is difficult to manage the use of the write combining buffers. Each operation may have a different effect on the use of the write combining buffers, ...
合并写(write combining) 现代CPU采用了大量的技术来抵消内存访问带来的延迟。读写内存数据期间,CPU能执行成百上千条指令。 多级SRAM缓存是减小这种延迟带来的影响的主要手段。此外,SMP系统采用消息传递协议来实现缓存之间的一致性。遗憾的是,现代的CPU实在是太快了,即使是使用了缓存,有时也无法跟上CPU的速度。因此,...

I have a question about write-combining. In the case of write-combinging(mapping with remap_pfn_range and pgprot_writecombine), CPU may buffer several writes within cache-aligned 64 bytes and then do a single real write. How does the CPU decide to ...
必应词典为您提供write-combiningbuffer的释义,网络释义: 写组合缓冲;写组合缓存;
WRITE COMBINING Once a memory region has been defined as having the WC memory type, accesses into the memory region will be subject to the architectural definition of WC: WC is a weakly ordered memory type. System memory locations are not cached and coherency is not enforced by the processor...
