Abstract: A cache memory stores 2^J-byte cache lines and includes an array of 2^N sets each holding tags each X bits, an input receives a Q-bit memory address, MA[(Q?1):0], having: a tag MA[(Q?1):(Q?X)] and an index MA[(Q?X?1):J]. Q is an integer at least (N+J+X?1). In a first mode: set selection logic selects one set using the index and LSB of the tag; comparison logic compares all but LSB of the tag with all but LSB of each tag in the selected set and indicates a hit if a match; otherwise allocation logic allocates into the selected set. In a second mode: the set selection logic selects two sets using the index; the comparison logic compares the tag with each tag in the selected two sets and indicates a hit if a match; and otherwise allocates into one set of the two selected sets.

Abstract: System and method of determining memory ownership on cache line basis for detecting self-modifying code. An ownership queue stores cache line addresses and corresponding ownership indexes. The cache line data is translated into instructions, and each instruction is provided with an ownership index of an associated entry in the ownership queue. Each new cache line address is compared with the destination address of each store instruction, and each destination address, when determined, is compared with each cache line address in the ownership queue. Matching entries are marked as stale, and each instruction derived from a stale entry causes an exception when ready to retire. In this manner, a hit between a cache line and a corresponding store instruction causes an exception. An exception flushes the processor to resolve the potential modified code condition.

Abstract: A processor that determines memory ownership on a cache line basis for detecting self-modifying code including modification of a cache line with an executing instruction. An ownership index and corresponding cache line address are entered for each cache line into an ownership queue. The ownership index is provided with each instruction derived from the cache line. When the instruction is issued, an executing bit is set in the corresponding entry. When a destination address of a store instruction matches an entry in the ownership queue, the store instruction is marked to invoke an executing exception if the executing bit of the entry is set. When a store instruction that is ready to retire is marked to invoke the executing exception, the store instruction is allowed to retire, the processor is flushed, and the next instruction after the store instruction is re-fetched to continue processing.

The delegate is executed using the loaded payload.

Abstract: Various aspects provide for managing data associated with a cache memory. For example, a system can include a cache memory and a memory controller. The cache memory stores data. The memory controller maintains a history profile for the data stored in the cache memory. In an implementation, the memory controller includes a filter component, a tagging component and a data management component. The filter component determines whether the data is previously stored in the cache memory based on a filter associated with a probabilistic data structure. The tagging component tags the data as recurrent data in response to a determination by the filter component that the data is previously stored in the cache memory. The data management component retains the data in the cache memory in response to the tagging of the data as the recurrent data.

In some embodiments, the translations are usable to access an area within the storage device used to store pages evicted from the memory. In one embodiment, a size of the memory allocation is determined based on a size of the area. In another embodiment, a size of the memory allocation is determined based on a size of a partition including the area. In some embodiments, the storage device is a solid-state storage array.

Abstract: A page table is a data structure used by a virtual memory system in a computer system to store the mapping between virtual addresses and physical addresses. Embodiments herein use a tree to map a virtual memory address space in the page table. The tree may be an N-ary tree where N is a power of two (e.g., 2, 4, 8, 16, etc.). The tree may include multiple levels that each correspond to a different page table size. For example, an octree includes eight different entries for each child node which may include per-thread sub-entries. Child nodes in the first level of the octree may each correspond to a 512 GiB page, while child nodes in the second level, however, may each have eight entries that correspond to a 64 GiB page. In this manner, an N-ary tree may be used to support a computing system with varying page sizes.

Abstract: A system and method of determining memory ownership on a cache line basis for detecting self-modifying code including code with looping instructions. An ownership queue includes multiple entries for determining memory ownership on a cache line basis. An ownership index and a wrap bit are determined for each cache line in the ownership queue, which are provided with each instruction derived from the same cache line. When an instruction is issued for execution, the ownership index provided with the instruction is used to access the corresponding entry in the ownership queue. If the instruction and entry wrap bits do not match, then an overwrite of the cache line is detected. The instruction is marked to invoke a first exception, which is performed when the instruction is ready to retire. The first exception flushes the processor, prevents the instruction from being retired, and re-fetches the instruction to continue processing.
