Method and apparatus for allocating instruction and data for a unified cache |
| 摘要 |
The present invention provides a method and apparatus for allocating space in a unified cache. The method may include partitioning the unified cache into a first portion of lines that only store copies of instructions retrieved from a memory and a second portion of lines that only store copies of data retrieved from the memory. |

1. A method, comprising:
partitioning a unified cache into a first portion of lines that only store copies of instructions retrieved from a memory, a second portion of lines that only store copies of data retrieved from the memory, a third portion of lines that store copies of either data or instructions retrieved from the memory; and modifying the partition of the unified cache in response to changes in a ratio of a replacement rate for instruction lines and a replacement rate for data lines in the unified cache and further in response to a current activity status of a device that implements the unified cache, the current activity status indicating whether the device is in a sleep mode. |
