A case for integrated processor-cache partitioning in chip multiprocessors
Existing cache partitioning schemes are designed in a manner oblivious to the implicit processor partitioning enforced by the operating system. This paper examines an operating sy...

Flexible cache error protection using an ECC FIFO
We present ECC FIFO, a mechanism enabling two-tiered last-level cache error protection using an arbitrarily strong tier-2 code without increasing on-chip storage. Instead of addin...
