The ARM Cortex-A72 is a
Overview
- Pipelined processor with deeply superscalarexecution pipeline
- DSP and SIMDextensions are mandatory per core
- VFPv4Floating Point Unit onboard (per core)
- Hardware virtualization support
- Thumb-2instruction set encoding reduces the size of 32-bit programs with little impact on performance.
- TrustZonesecurity extensions
- Program Trace Macrocell and CoreSight Design Kit for unobtrusive tracing of instruction execution
- 32 KiB data (2-way set-associative) + 48 KiB instruction (3-way set-associative) L1 cache per core
- Integrated low-latency level-2 (16-way set-associative) cache controller, 512 KB to 4 MB configurable size per cluster
- 48-entry fully associative L1 instruction translation lookaside buffer (TLB) with native support for 4 KiB, 64 KiB, and 1 MB page sizes
- 32-entry fully associative L1 data TLB with native support for 4 KiB, 64 KiB, and 1 MB page sizes
- 4-way set-associative of 1024-entry unified L2 TLB per core, supports hit-under-miss
- Sophisticated branch prediction algorithm that significantly increases performance and reduces energy from misprediction and speculation
- Early IC tag –3-way L1 cache at direct-mapped power*
- Regionalized TLB and μBTB tagging
- Small-offset branch-target optimizations
- Suppression of superfluous branch predictor accesses
