PRE-LOADING CACHE LINES
A system for caching is configured for a pending lock state of a cache line, pre-loading the cache line into cache memory, and locking the cache line to prevent eviction of the cache line from the cache memory. The cache line is associated with instructions or data, and the pre-loading of the cache line may include loading the cache line into the cache memory before an algorithm relying on the instructions or data needs them. The pre-loading of a cache line associated with instructions may be done without execution of the instructions. The pending lock state of the cache line may be achieved by configuring the cache system to know that, when a cache line associated with an address is loaded into the cache memory, it should lock the cache line. The locking of the cache line may be done by promoting the pending lock state to a locked state.
1 . A method for caching using a cache system, the method comprising the steps of:
configuring the cache system for a pending lock state of a cache line;
pre-loading the cache line into cache memory; and
locking the cache line to prevent eviction of the cache line from the cache memory.
2 . The method of claim 1 , wherein pre-loading the cache line includes loading the cache line associated with instructions or data into the cache memory before an algorithm relying on the instructions or data needs them.
3 . The method of claim 2 , wherein pre-loading the cache line associated with instructions is done without execution of the instructions.
4 . The method of claim 1 , wherein the pending lock state is achieved by configuring the cache system to know that, when a cache line associated with an address is loaded into the cache memory, it should lock the cache line.
5 . The method of claim 4 , wherein the address is associated with instructions or data.
6 . The method of claim 1 , wherein locking the cache line is done by promoting the pending lock state to a locked state.
7 . The method of claim 1 , further comprising the step of unlocking the cache line to allow for eviction of the cache line from cache memory.
8 . A computer-readable storage medium storing instructions that when executed by a computer causes the computer to perform a method for caching using a cache system, the method comprising the steps of:
configuring the cache system for a pending lock state of a cache line;
pre-loading the cache line into cache memory; and
locking the cache line to prevent eviction of the cache line from the cache memory.
9 . A cache system comprising
a cache controller, a processor, and memory that are all operatively coupled to each other and configured to:
establish a pending lock state of a cache line;
pre-load the cache line into cache memory; and
lock the cache line to prevent eviction of the cache line from the cache memory.
10 . The cache system of claim 9 , wherein the cache system is configured to pre-load a plurality of cache lines simultaneously.
