Device and method for generating cache user initiated pre-fetch requests
View Patent ↗A method for generating cache user initiated pre-fetch requests, the method comprises initiating a sequence of user initiated pre-fetch requests; the method being characterized by: determining the timing of user initiated pre-fetch requests of the sequence of user initiated pre-fetch requests in response to: the timing of an occurrence of a last triggering event, a user initiated pre-fetch sequence delay period and a user initiated pre-fetch sequence rate.
1. A method for generating user initiated cache pre-fetch requests, the method comprises:
initiating a sequence of user initiated pre-fetch requests;
determining a timing of user initiated pre-fetch requests of the sequence of user initiated pre-fetch requests in response to: a timing of an occurrence of a last triggering event, a user initiated pre-fetch sequence delay period and a user initiated pre-fetch sequence rate.
2. The method according to claim 1 , further comprising defining the user initiated pre-fetch sequence delay period and the user initiated pre-fetch sequence rate.
3. The method according to claim 2 , wherein the stage of defining comprises:
evaluating a relationship between cache performance, values of the user initiated pre-fetch sequence delay period and of the user initiated pre-fetch sequence rate; and
updating the values of the user initiated pre-fetch sequence delay period and of the user initiated pre-fetch sequence rate, in response to the relationship evaluated.
4. The method according to claim 1 , further comprising receiving the user initiated pre-fetch sequence delay period and the user initiated pre-fetch sequence rate.
5. The method according to claim 1 , further comprising evaluating an impact of the user initiated pre-fetch sequence delay period and the user initiated pre-fetch sequence rate on cache performance.
6. The method according to claim 1 , further comprising generating an indication that values of the user initiated pre-fetch sequence delay period and the user initiated pre-fetch sequence rate should be altered in response to an evaluation of an impact of the user initiated pre-fetch sequence delay period and the user initiated pre-fetch sequence rate on cache performance.
7. A device which has user initiated pre-fetch capabilities, comprising:
a cache module; and
a high-level memory access controller adapted to: (i) determine a timing of user initiated pre-fetch requests of a sequence of user initiated pre-fetch requests in response to a timing of an occurrence of a last triggering event, a user initiated pre-fetch sequence delay period and a user initiated pre-fetch sequence rate, and (ii) initiate the sequence of user initiated pre-fetch requests in response to the determination.
8. The device according to claim 7 , further adapted to define the user initiated pre-fetch sequence delay period and the user initiated pre-fetch sequence rate.
9. The device according to claim 7 , further adapted to receive the user initiated pre-fetch sequence delay period and the user initiated pre-fetch sequence rate.
10. The device according to claim 7 , adapted to evaluate an impact of the user initiated pre-fetch sequence delay period and the user initiated pre-fetch sequence rate on cache performance.
11. The device according to claim 7 , further adapted to generate an indication that values of the user initiated pre-fetch sequence delay period and the user initiated pre-fetch sequence rate should be altered in response to the evaluation of an impact of the user initiated pre-fetch sequence delay period and the user initiated pre-fetch sequence rate on cache performance.
