Elements of art are stylistic features that are included within an art piece to help the artist communicate. [1] The seven most common elements include line, shape, texture, form, space, color and value, with the additions of mark making, and materiality.
Cache placement policies are policies that determine where a particular memory block can be placed when it goes into a CPU cache.A block of memory cannot necessarily be placed at an arbitrary location in the cache; it may be restricted to a particular cache line or a set of cache lines [1] by the cache's placement policy.
Once the cache block is in the Modified (M) state and there is a bus read (BusRd) request, the block flushes (Flush) the modified data and changes the state to owned (O), thus making it the sole owner for that particular cache block. At the same time, when it is in the modified (M) state, there is never going to be a bus write request (BusUpgr ...
A CPU cache is a hardware cache used by the central processing unit (CPU) of a computer to reduce the average cost (time or energy) to access data from the main memory. [1] A cache is a smaller, faster memory, located closer to a processor core, which stores copies of the data from frequently used main memory locations.
This cache does not have permission to modify the copy. Unlike the MESI protocol, a shared cache line may be dirty with respect to memory; if it is, one cache has a copy in the Owned state, and that cache is responsible for eventually updating main memory. If no cache holds the line in the Owned state, the memory copy is up to date.

The detachment of wall paintings involves the removal of a wall painting from the structure of which it formed part. While detachment was once a common practice, the preservation of art in situ is now preferred, and detachment is now largely restricted to cases where the only alternative is total loss. [ 1 ]
In this protocol, each block in the local cache is in one of these four states: Invalid: This block has an incoherent copy of the memory. Valid: This block has a coherent copy of the memory. The data may be possibly shared, but its content is not modified. Reserved: The block is the only copy of the memory, but it is still coherent. No write ...
