The page cache bit controls the meaning of the write buffer bit. When the cache bit is zero, the buffer bit enables the write buffer when the buffer bit value is one, and disables the write buffer when the buffer bit value is zero. When the cache bit is set to one, the write ...
First, writes are generally sent to the memory controller at the time of cacheline fills, meaning that idle cycles on the memory bus cannot be utilized for write operations. Second, the forced writebacks do not necessarily correlate with efficiently accessible locations in memory. However, the ...
1. A device comprising: an input/output (IO) interface to couple the device to a processor over a link; a plurality of processing engines; a plurality of work queues to store descriptors of work to be executed by a processing engine of the device; and a plurality of arbiters comprising ...
MemFiles makes an initial allocation of 1048576 bytes for each file; as data is written to memory, it can and will expand this allocation as needed to hold larger files. The filename stored in the MemFiles struct is parsed out of an argument that is passed to the replacement NtCreateFile...
The kernel has to traverse a more vast filesystem hierarchy and hence that without a doubt is an overhead. Another point to note is that as you increase the number of directories, the inode and dentry cache usage will climb up meaning consumption of more RAM. This comes under...

Hence, no limitation, element, property, feature, advantage or attribute that is not expressly recited in a claim should...
In a block-oriented memory architecture, the cache has multiple functions, not merely to improve access speed, but is an integral part of a sequential update block system. The cache memory has a capacity dynamically increased by allocation of blocks from the main memory in response to a demand...
the memory and executable by the processor to cause the processor to, upon allocation of space by the second logic, indicate to the second requestor that they may store the second data to the selected data store beginning at the computed second location; andwhereby, responsive to the indication...
