Abstract: An apparatus and method are provided for controlling allocation of instructions into an instruction cache storage. The apparatus comprises processing circuitry to execute instructions, fetch circuitry to fetch instructions from memory for execution by the processing circuitry, and an instruction cache storage to store instructions fetched from the memory by the fetch circuitry. Cache control circuitry is responsive to the fetch circuitry fetching a target instruction from a memory address determined as a target address of an instruction flow changing instruction, at least when the memory address is within a specific address range, to prevent allocation of the fetched target instruction into the instruction cache storage unless the fetched target instruction is at least one specific type of instruction. It has been found that such an approach can inhibit the performance of speculation-based caching timing side-channel attacks.

Abstract: An apparatus and method of operating a data processing apparatus are disclosed. The apparatus comprises data processing circuitry to perform data processing operations in response to a sequence of instructions, wherein the data processing circuitry is capable of performing speculative execution of at least some of the sequence of instructions. A cache structure comprising entries stores temporary copies of data items which are subjected to the data processing operations and speculative execution tracking circuitry monitors correctness of the speculative execution and responsive to indication of incorrect speculative execution to cause entries in the cache structure allocated by the incorrect speculative execution to be evicted from the cache structure.

Abstract: Anomalous control and data flow paths in a program are determined by machine learning the program's normal control flow paths and data flow paths. A subset of those paths also may be determined to involve sensitive data and/or computation. Learning involves collecting events as the program executes, and associating those event with metadata related to the flows. This information is used to train the system about normal paths versus anomalous paths, and sensitive paths versus non-sensitive paths. Training leads to development of a baseline “provenance” graph, which is evaluated to determine “sensitive” control or data flows in the “normal” operation. This process is enhanced by analyzing log data collected during runtime execution of the program against a policy to assign confidence values to the control and data flows. Using these confidence values, anomalous edges and/or paths with respect to the policy are identified to generate a “program execution” provenance graph associated with the policy.

Abstract: Examples of the present disclosure relate to an apparatus comprising execution circuitry to execute instructions defining data processing operations on data items. The apparatus comprises cache storage to store temporary copies of the data items. The apparatus comprises prefetching circuitry to a) predict that a data item will be subject to the data processing operations by the execution circuitry by determining that the data item is consistent with an extrapolation of previous data item retrieval by the execution circuitry, and identifying that at least one control flow element of the instructions indicates that the data item will be subject to the data processing operations by the execution circuitry; and b) prefetch the data item into the cache storage.

Abstract: An apparatus (2) has processing circuitry to process micro-operations, the processing circuitry supporting speculative processing of read micro-operations for reading data from a memory system. A cache (6, 8) is provided to cache the micro-operations or instructions decoded to generate the micro-operations. Profiling circuitry (40) annotates at least one cached micro-operation or instruction with annotation information depending on analysis of whether a read micro-operation satisfies a speculative side-channel condition indicative of a risk of information leakage if the read micro-operation is processed speculatively. The processing circuitry (12, 14) determines whether to trigger a speculative side-channel mitigation measure depending on the annotation information stored in the cache (6, 8).

Abstract: An apparatus comprises processing circuitry 14 to perform data processing in response to instructions, the processing circuitry supporting speculative processing of read operations for reading data from a memory system 20, 22; and control circuitry 12, 14, 20 to identify whether a sequence of instructions to be processed by the processing circuitry includes a speculative side-channel hint instruction indicative of whether there is a risk of information leakage if at least one subsequent read operation is processed speculatively, and to determine whether to trigger a speculative side-channel mitigation measure depending on whether the instructions include the speculative side-channel hint instruction. This can help to reduce the performance impact of measures taken to protect against speculative side-channel attacks.

Abstract: A balloon catheter (1) including a device (3) adjacent the distal end (12) of a catheter (10) for guiding a boring tool (5) or other instrument into an occlusion (6) in a vessel (8), includes a guide element (30) adjacent the distal end (12). A penetrating element (33) having a first guide bore (38) terminating in a distal cutting edge (40) is rotatable in a second guide bore (45) extending through the guide element. External threads on the penetrating element (33) are engageable with internal threads in the second guide bore (45), so that by rotating the penetrating element (33) the distal cutting edge (40) is urged outwardly to penetrate the occlusion (6). With the penetrating element (33) securely engaged in the occlusion (6), a boring tool (5) and other instruments can then be sequentially guided through the catheter (10) and the first guide bore (38) directly into the occlusion.
