In paper [18] Xu and Chen proposed the prediction based prefetching technique which is used to prefetch the video segments based on the prediction of user's interest.
With prediction, the number of classes [S.sub.C] satisfied by the server, where the client is forced to request, block and wait for a class stream, is 4 less because the server has anticipated their use, then prefetched and transmitted them to the CCC.
Then, when a cache-line is brought into the cache it also effectively prefetches the data that is to be needed in the near future.
There are generally two ways to prefetch. In in-line or synchronous prefetching, the prefetch is tagged into a demand fetch, and the transaction is blocked until the entire I/O request is completed.
To further expand the scope of prefetching to capture more control transfer targets, Smith and Hsu [1992] proposed target-line prefetching which uses a prediction table to record the address of the line which most recently followed a given instruction line, thus enabling hardware to prefetch targets whenever an entry is found in this table.
The conservative strategy incurs the same faults as Belady's optimal paging algorithm [Belady 1966], but starts prefetch operations at the earliest possible point in time.
It is because three-stage copy speeds up the transmission by the means of active push and prefetch pages after the VMs resume.
ALGORITHM 1 divide X and Y into blocks X' and Y' of size (PE x cache depth); For each block of X1 and Y1 do prefetch Y' into cache via stream C; preload any W, [alpha], [beta] or Z' to stream B; for each row of X1 do stream new elements of the row of X' via S; multiply-accumulate elements of X' and Y'across PEs; if Z'contains final elements of XY then shift new partial results of Z' from PEs via P; perform scalar operations using [alpha], [beta] and W at output of P and B via ASE ([section] 3.3); else shift new elements of Z1 from PEs via P to memory or cache; end end end 4.
"It beats the usual DICOM pull or prefetch technology, and it works well with our workflow."
Although, in Figure 4, slave-side interface modules share the access to the interconnect, multiple other HW tasks may prefetch the data to storage contained in these modules, one after another, while the HW Task Core is executing.
Class file prefetching inserts special prefetch instructions into the Java class file to overlap bytecode transfer with execution.
Under this scheme, the cache would prefetch the next N sequential lines after the line currently being executed.
