ALUs that perform arithmetic and logical data processing operations and a fourth port which has support for complex arithmetic (e.g. MAC, DIV). Cortex-A77 also added a second branch ALU, doubling the throughput for branches.

There are two ASIMD/FP execution pipelines. This is unchanged from Cortex-A76. What did change is the issue queues. As with the integer cluster, the ASIMD cluster now features a unified issue queue for both pipelines, improving efficiency. As with Cortex-A76, the ASIMD on Cortex-A77 are both 128-bit wide capable of
