Cache prefetching can be accomplished either by hardware or by software. [3]Hardware based prefetching is typically accomplished by having a dedicated hardware mechanism in the processor that watches the stream of instructions or data being requested by the executing program, recognizes the next few elements that the program might need based on this stream and prefetches into the processor's ...
A memory leak can cause an increase in memory usage and performance run-time, and can negatively impact the user experience. [4] Eventually, in the worst case, too much of the available memory may become allocated and all or part of the system or device stops working correctly, the application fails, or the system slows down vastly due to ...
The Cortex-X1 design is based on the ARM Cortex-A78, but redesigned for purely performance instead of a balance of performance, power, and area (PPA). [1]The Cortex-X1 is a 5-wide decode out-of-order superscalar design with a 3K macro-OP (MOPs) cache.
The Cortex-A55 serves as the successor of the ARM Cortex-A53, designed to improve performance and energy efficiency over the A53. [3] ARM has stated the A55 should have 15% improved power efficiency and 18% increased performance relative to the A53. Memory access and branch prediction are also improved relative to the A53.
Memory cells that use fewer than four transistors are possible; however, such 3T [27] [28] or 1T cells are DRAM, not SRAM (even the so-called 1T-SRAM). Access to the cell is enabled by the word line (WL in figure) which controls the two access transistors M 5 and M 6 in 6T SRAM figure (or M 3 and M 4 in 4T SRAM figure) which, in turn, control ...
Its mitigations incur a slight performance degradation. [75] In April 2024, it was revealed that the BHI vulnerability in certain Intel CPU families could be still exploited in Linux entirely in user space without using any kernel features or root access despite existing mitigations. [76] [77] [78] Intel recommended "additional software ...

The performance increase of the 80286 over the 8086 (or 8088) could be more than 100% per clock cycle in many programs (i.e., a doubled performance at the same clock speed). This was a large increase, fully comparable to the speed improvements seven years later when the i486 (1989) or the original Pentium (1993) were introduced.
