Corpus analysis for Prefetch
- In this selection, "prefetch" usually appears near the end of the sentence. The average example has 33.9 words, and this corpus slice is mostly made up of statements.
- Around the word, byte, instruction, queue, algorithm and depth stand out and add context to how "prefetch" is used.
- Recognizable usage signals include 4 byte prefetch queue to and and the prefetch algorithm was. That gives this page its own corpus information beyond isolated example sentences.
- By corpus frequency, "prefetch" sits close to words such as aakash, aanholt and aardwolf, which helps place it inside the broader word index.
Example types with prefetch
The same corpus examples are grouped by length and sentence type, making it easier to see the contexts in which the word appears:
DDR3 advances extended the ability to preserve internal clock rates while providing higher effective transfer rates by again doubling the prefetch depth. (22 words)
For example, a repeated string operation or a shift by three or more will take long enough to allow time for the 4-byte prefetch queue to completely fill. (29 words)
The prefetch queue of the 8088 was shortened to four bytes, from the 8086's six bytes, and the prefetch algorithm was slightly modified to adapt to the narrower bus. (30 words)
DDR's prefetch buffer depth is 2 (bits), while DDR2 uses 4. Although the effective clock rates of DDR2 are higher than DDR, the overall performance was no greater in the early implementations, primarily due to the high latencies of the first DDR2 modules. (44 words)
Any conditional jump requires 4 clock cycles if not taken, but if taken it requires 16 cycles in addition to resetting the prefetch queue; therefore, conditional jumps should be arranged to be not taken most of the time, especially inside loops. (41 words)
The speed of the execution unit (EU) and the bus of the 8086 CPU was well balanced; with a typical instruction mix, an 8086 could execute instructions out of the prefetch queue a good bit of the time. (38 words)

For example, a repeated string operation or a shift by three or more will take long enough to allow time for the 4-byte prefetch queue to completely fill.
The reasons why most memory related instructions were slow were threefold: * Loosely coupled fetch and execution units are efficient for instruction prefetch, but not for jumps and random data access (without special measures).
Therefore, for example, a 2-byte shift or rotate instruction, which takes the EU only 2 clock cycles to execute, actually takes eight clocks to complete if it is not in the prefetch queue.
The speed of the execution unit (EU) and the bus of the 8086 CPU was well balanced; with a typical instruction mix, an 8086 could execute instructions out of the prefetch queue a good bit of the time.
