Combining Two Or More Values To Create Address Patents (Class 711/220)
  • Patent number: 11266911
    Abstract: The technology described implements attestation programs that employ “code reuse” techniques. In particular, the technology relates to auto-generating attestation programs for, among other aspects, detecting whether a program has been modified. In one non-limiting example, the technology uses a tool that scans a software program (e.g., a video game) code for usable code sequences. The tool can automatically combine code sequences to generate a large number of attestation programs of different variety (e.g., memory checks, hashing).

  • Patent number: 10671391
    Abstract: In an aspect, a processor supports modeless execution of 64 bit and 32 bit instructions. A Load/Store Unit (LSU) decodes an instruction that without explicit opcode data indicating whether the instruction is to operate in a 32 or 64 bit memory address space. LSU treats the instruction either as a 32 or 64 bit instruction in dependence on values in an upper 32 bits of one or more 64 bit operands supplied to create an effective address in memory. In an example, a 4 GB space addressed by 32-bit memory space is divided between upper and lower portions of a 64-bit address space, such that a 32-bit instruction is differentiated from a 64-bit instruction in dependence on whether an upper 32 bits of one or more operands is either all binary 1 or all binary 0. Such a processor may support decoding of different arithmetic instructions for 32-bit and 64-bit operations.

  • Patent number: 9118618
    Abstract: Hardware-based packet editor receives a packet editing script which includes script entries indicating modifications to a data packet and a data block with data for the modified data packet. For a script entry in the packet editing script, the packet editor copies data in the data block at a block location and with a block length identified in the script entry into a packet buffer. The packet editor repeats the copying for the remaining script entries for the modified data packet. The packet editor then generates the modified data packet with the data in the packet buffer. The packet editing script is generated such that a script entry is created for data to be included in the modified data packet and data to be inserted into the modified data packet. Creation of a script entry is omitted for data to be removed.

  • Patent number: 9009441
    Abstract: In general, this disclosure describes techniques for selecting a memory channel in a multi-channel memory system for storing data, so that usage of the memory channels is well-balanced. A request to write data to a logical memory address of a memory system may be received. The logical memory address may include a logical page number and a page offset, where the logical page number maps to a physical page number and the logical memory address maps to a physical memory address. A memory unit out of a plurality of memory units in the memory system may be determined by performing a logical operation on one or more bits of the page offset and one or more bits of the physical page number. The data may be written to a physical memory address in the determined memory unit in the memory system.

  • Patent number: 8972697
    Abstract: Methods and apparatus are disclosed for using an index array and finite state machine for scatter/gather operations. Embodiment of apparatus may comprise: decode logic to decode a scatter/gather instruction and generate a set of micro-operations, and an index array to hold a set of indices and a corresponding set of mask elements. A finite state machine facilitates the gather operation. Address generation logic generates an address from an index of the set of indices for at least each of the corresponding mask elements having a first value. An address is accessed to load a corresponding data element if the mask element had the first value. The data element is written at an in-register position in a destination vector register according to a respective in-register position the index. Values of corresponding mask elements are changed from the first value to a second value responsive to completion of their respective loads.

  • Patent number: 8954711
    Abstract: A data processing apparatus is provided comprising processing circuitry and an instruction decoder responsive to program instructions to control processing circuitry to perform the data processing. The instruction decoder is responsive to an address calculating instruction to perform an address calculating operation for calculating a partial address result from a non-fixed reference address and a partial offset value such that a full address specifying a memory location of an information entity is calculable from said partial address result using at least one supplementary program instruction. The partial offset value has a bit-width greater than or equal to said instruction size and is encoded within at least one partial offset field of said address calculating instruction. A corresponding data processing method, virtual machine and computer program product are also provided.

    Abstract: An example hashing unit includes a plurality of hardware-based hash tables, wherein each of the hash tables comprises a plurality of buckets, and wherein the plurality of hash tables comprise a set of zero or more active hash tables and a set of one or more inactive hash tables. An example hashing unit controller is configured to receive a key value to be stored in the hashing unit, determine that one of the inactive hash tables should be activated, and, based on the determination, activate the one of the set of inactive hash tables as a recently activated hash table, determine one of the buckets of the recently activated hash table to which a hash function associated with the recently activated hash table maps the received key value, and store the key value in the determined one of the buckets of the recently activated hash table.

  • Patent number: 8930675
    Abstract: A transactional memory (TM) receives a lookup command across a bus from a processor. The command includes a memory address. In response to the command, the TM pulls an input value (IV). The memory address is used to read a word containing multiple result values (RVs), multiple reference values, and multiple mask values from memory. A selecting circuit within the TM uses a starting bit position and a mask size to select a portion of the IV. The portion of the IV is a lookup key value (LKV). The LKV is masked by each mask value thereby generating multiple masked values. Each masked value is compared to a reference value thereby generating multiple comparison values. A lookup table generates a selector value based upon the comparison values. A result value is selected based on the selector value. The selected result value is then communicated to the processor via the bus.

    Abstract: Various systems, processes, products, and techniques may be used to manage legacy data. In one general implementation, a system, process, and/or product for managing legacy data may include the ability to determine whether a data request has been received and, if a data request has been received, determine whether the data request is associated with legacy data of an external storage management system. If the data request is not associated with legacy data of an external storage management system, the system, process, and/or product may retrieve data from a local storage array, and if the data request is associated with legacy data of an external storage management system, the system, process, and/or product may request legacy data from an external storage management system. The system, process, and/or product may also generate a response to the data request.
