ARM's DynamIQ technology, and is expected to be used as high-performance cores in combination with Cortex-A55 power-efficient cores. Architecture changes in comparison with ARM Cortex-A76 Front-end Branch-prediction Better accuracy Up to 64B runahead window (From 32B) Increase L1 BRB capacity, up to 64-entry (From 16-entry) Increase BTB capacity, up to 8K-entry (From 6K-entry) Improved prefetcher Add new L0 Macro-op cache Wider instruction fetch, up to 6 instructions/cycle (From 4 instructions/cycle) Execution engine Wider instruction fetch, Up to 6 instructions/cycle (From 4 instructions/cycle) Larger Re-Order Buffer, Up to 160-entry (From 128-entry) Wider dispatch, uo to 10-way, (From 8-way) Wider issue, up to 12-way (From 8-way) Execution units New integer ALU unit and port New branch unit and port New dedicated store data ports New AES unit added Licensing The Cortex-A77 is available as SIP core to licensees, and its design makes it suitable for integration with other SIP cores (e.g. GPU, display controller, DSP, image processor, etc.) into one die constituting a system on a chip (SoC). Usage The Samsung Exynos 980 was introduced in September 2019 as the first SoC to use the Cortex-A77 microarchitecture. This was later followed by a lower-end variant Exynos 880 in May 2020. The MediaTek Dimensity 1000, 1000L and 1000+ SoCs also utilizes the Cortex-A77 microarchitecture. Derivatives by the names of Kryo 585, Kryo 570 and Kryo 560, are used in the Snapdragon 865, 750G, and 690 respectively.
