NXP Semiconductors QorIQ LS1012A Reference Manual

LS1012A features one high-performance Cortex-A53 core:• 64 and 32-bit execution states for scalable high performance• Coherent interconnect supporting AMBA® 4 technology• New instruction set, A64• In-order pipeline with symmetric dual-issue of most instructions• 32 KB instruction cache, 32 KB data cache, 256 KB unified L2 cache• NEON technology - Accelerates multimedia and signal processing algorithms suchas video encode/decode, 2D/3D graphics, gaming, audio and speech processing,image processing, telephony, and sound synthesis. Also useful in acceleratingfloating point code with SIMD execution.• Hardware-accelerated cryptography - 3x-10x better software encryption performanceUseful for small granule decrypt/encrypt too small to efficiently offload to HWaccelerator (e.g. https)• Floating point unit - Hardware support for floating point operations in half-, single-and double-precision floating point arithmetic. IEE754-2008 enhancements areincluded.• TrustZone® Technology - Ensures reliable implementation of security applicationsranging from digital rights management to electronic payment.• Double Precision Floating Point SIMD - Allows SIMD vectorisation to be applied toa much wider set of algorithms (e.g. scientific / High Performance Computing (HPC)and supercomputer).• 64-bit Virtual address reach - Enables virtual memory beyond 4GB 32b limit.Important for modern desktop and server software using memory mapped file I/O,sparse addressing.• Enhanced Cache management - User space cache operations improve dynamic codegeneration efficiency, Data Cache Zero for fast clear.• Power-saving features - Hierarchical clock gating• Hardware virtualization support6.3 Arm generic interrupt controller (GIC-400)Generic interrupt controller (GIC) is a centralized resource for supporting and managinginterrupts in a system that includes at least one processor. It provides:• registers for managing interrupt sources, interrupt behavior, and interrupt routing toone or more processors• support for the following:• the Arm architecture security extensions• the Arm architecture virtualization extensionsArm generic interrupt controller (GIC-400)QorIQ LS1012A Reference Manual, Rev. 1, 01/2018262 NXP Semiconductors
