  • Publication number: 20250116004
    Abstract: Provided is a substrate processing apparatus. The positions of a first electrode and a second electrode are adjusted in advance in consideration of differences in coefficients of thermal expansion so that a short circuit created by contact between the first electrode and the second electrode is prevented even in the case in which the first electrode and the second electrode are thermally expanded during processing. Even in the case in which the first electrode and the second electrode are thermally expanded due to an increase in temperature during processing, a short circuit between the first electrode and the second electrode can be prevented, and the uniformity of a thin film can be maintained in the substrate processing apparatus for processing a large substrate.

  • Publication number: 20240329999
    Abstract: An apparatus is provided for limiting the effective utilisation of an instruction fetch queue. The instruction fetch entries are used to control the prefetching of instructions from memory, such that those instructions are stored in an instruction cache prior to being required by execution circuitry while executing a program. By limiting the effective utilisation of the instruction fetch queue, fewer instructions will be prefetched and fewer instructions will be allocated to the instruction cache, thus causing fewer evictions from the instruction cache. In the event that the instruction fetch entries are for instructions that are unnecessary to the program, the pollution of the instruction cache with these unnecessary instructions can be mitigated.

  • Publication number: 20230195468
    Abstract: An apparatus has a fetch queue to identify a sequence of instructions to be fetched for execution and prediction circuitry to predict upcoming control flow and to control which instructions are identified in the fetch queue in dependence on the prediction. The prediction circuitry predicts multi-taken sequences which are sequences of instructions in which control flow is diverted by a first control flow changing instruction to a series of instructions terminating in a second control flow changing instruction that diverts control flow to a target address. The apparatus also has prediction confidence calculation circuitry to calculate confidence levels for respective multi-taken sequences. Each confidence level is indicative of a confidence in an accuracy of prediction of its respective multi-taken sequence.

  • Patent number: 11455253
    Abstract: An apparatus comprises first-level and second-level set-associative caches each comprising the same number of sets of cache entries. Indexing circuitry generates, based on a lookup address, a set index identifying which set of the first-level set-associative cache or the second-level set-associative cache is a selected set of cache entries to be looked up for information associated with the lookup address. The indexing circuitry generates the set index using an indexing scheme which maps the lookup address to the same set index for both the first-level set-associative cache and the second-level set-associative cache. This can make migration of cached information between the cache levels more efficient, which can be particularly useful for caches with high access frequency, such as branch target buffers for a branch predictor.

  • Patent number: 11379377
    Abstract: First and second-level caches are provided. Cache control circuitry performs a first-level cache lookup of the first-level cache based on a lookup address, to determine whether the first-level cache stores valid cached data corresponding to the lookup address. When lookup hint information associated with the lookup address is available, the cache control circuitry determines based on the lookup hint information whether to activate or deactivate a second-level cache lookup of the second-level cache. The lookup hint information is indicative of whether the second-level cache is predicted to store valid cached data associated with the lookup address. When the second-level cache lookup is activated, the second-level cache lookup of the second-level cache is performed based on the lookup address to determine whether the second-level cache stores valid cached data corresponding to the lookup address.
