PRODUCTION DATA
The SoC implements one cluster of quad-core Arm® Cortex®-A53 MPCore™, with 32KB L1 instruction, 32KB L1 data, per core and 512KB L2 shared cache.
The Cortex®-A53 cores are general-purpose processors that can be used for running customer applications.
Notes on references used in this document:
The A53SS is built around the Cortex®-A53 MPCore™ (Arm®-A53 Cluster), which is provided by Arm and configured by TI. It is based on the symmetric multiprocessor (SMP) architecture, and thus, it delivers high performance and optimal power management, debug and emulation capabilities.
The A53 processor is a multi-issue out-of-order superscalar execution engine with integrated L1 Instruction and Data Caches, compatible with Arm®v8-A architecture. It delivers significantly more performance than its predecessors at a higher level of power efficiency.
The Arm®v8-A architecture brings a number of new features. These include 64-bit data processing, extended virtual addressing and 64-bit general purpose registers. The A53 processor is Arm’s first Arm®v8-A processor aimed at providing power-efficient 64-bit processing. It features an in-order, 8-stage, dual-issue pipeline, and improved integer, Arm® Neon™, Floating-Point Unit (FPU) and memory performance.
The A53 CPU supports two execution states: AArch32 and AArch64. The AArch64 state gives the A53 CPU its ability to execute 64-bit applications, while the AArch32 state allows the processor to execute existing Arm®v7-A applications.
