Armv7 Neon Zip !!top!! Direct

: Uses 32 registers of 64 bits each (D0–D31), which can also be viewed as 16 registers of 128 bits each (Q0–Q15). 2. High-Performance Deployment (The "ZIP" Workflow)

@ We need to process 8 elements at a time (4 from A, 4 from B) @ Loop unrolling is implied for simplicity LOOP: CMP r3, #4 BLT END armv7 neon zip

: Unlike later ARMv8-A versions, VZIP in ARMv7 typically operates "in-place," meaning it modifies the source registers directly to store the interleaved results. Core Architecture and Features : Uses 32 registers of 64 bits each
