Abstract
In one embodiment of the invention, data values which are provided to a non-tagged, n-way cache are written into the cache in a non-count form. Whereas a counter tends to quickly saturate to one extreme or the other (e.g., all zeros or all ones), or briefly take on a value which approaches an extreme, a non-count data value (e.g., branch prediction history bits) tends to assume a wider variety of values.
