  • Adaptive replacement cache
    Publication number: 20070106846
    Abstract: A method for caching a block, which includes receiving a request to store the block in a cache and determining whether the cache is able to expand. If the cache is not able to expand, then determining whether evictable blocks are present in the cache and, if evictable blocks are present in the cache determining whether a total size of the evictable blocks is greater than or equal to a size of the block, evicting a sufficient number of the evictable blocks from the cache and storing the block in the cache, if the total size of the evictable blocks is greater than or equal to the size of the block, and activating a cache throttle, if the total size of the evictable blocks is less than the size of the block.

  • Microprocessor resistant to power analysis
    Patent number: 7205794
    Abstract: A secure microprocessor is designed using quad-coded logic which is similar to dual-rail encoded asynchronous logic except that the ‘11’ state propagates an alarm. The alarm signal obliterates secure data in its path. Quad-coded logic provides resilience to power glitches and single-transistor or single-wire failures. The already low data dependency of the power consumption makes power analysis attacks difficult, and they are made even more difficult by inserting random delays in data and control paths, and by a set-random-carry instruction which enables software to make a non-deterministic choice between equivalent instruction sequences. These features are particularly easy to implement well in quad-coded logic.
