微处理器 - MPU Sitara Processor: Quad Arm Cortex-A15 1089-FCBGA -40 to 100
The AM5K2E0x is a high performance device based on s KeyStone II Multicore SoC Architecture, incorporating the most performance-optimized Cortex-A15 processor dual-core or quad-core CorePac that can run at a core speed of up to 1.4 GHz. TIs AM5K2E0x device enables a high performance, power-efficient and easy to use platform for developers of a broad range of applications such as enterprise grade networking end equipment, data center networking, avionics and defense, medical imaging, test and automation.
TIs KeyStone II Architecture provides a programmable platform integrating various subsystems for example, ARM CorePac Cortex-A15 Processor Quad Core CorePac, network processing, and uses a queue-based communication system that allows the device resources to operate efficiently and seamlessly. This unique device architecture also includes a TeraNet switch that enables the wide mix of system elements, from programmable cores to high-speed IO, to each operate at maximum efficiency with no blocking or stalling.
The AM5K2E0x KeyStone II device integrates a large amount of on-chip memory. The Cortex-A15 processor cores each have 32KB of L1Data and 32KB of L1 Instruction cache. The up to four Cortex A15 cores in the ARM CorePac share a 4MB L2 Cache. The device also integrates 2MB of Multicore Shared Memory MSMC that can be used as a shared L3 SRAM. All L2 and MSMC memories incorporate error detection and error correction. For fast access to external memory, this device includes a 64-bit DDR-3 72-bit with ECC support external memory interface EMIF running at 1600 MTPS.
The device enables developers to use a variety of development and debugging tools that include GNU GCC, GDB, Open source Linux, Eclipse based debugging environment enabling kernel and user space debugging using a variety of Eclipse plug-ins including TI"s industry leading IDE Code Composer Studio.
