AM387x Sitara ARM processors are highly integrated, programmable platforms that leverage the Sitara processor technology.
The device enables Original-Equipment Manufacturers (OEMs) and Original-Design Manufacturers (ODMs) to quickly bring to market devices featuring robust operating systems support, rich user interfaces, and high processing performance through the maximum flexibility of a fully integrated mixed processor solution. The device also combines programmable ARM processing with a highly integrated peripheral set.
The AM387x Sitara ARM processors also present OEMs and ODMs with new levels of processor scalability and software reuse. An OEM or ODM who used the AM387x processors in a design and can make a similar product with added features could scale up to the pin-compatible and software-compatible TMS320DM814x processors from TI. The TMS320DM814x DaVinci video processors add a powerful C674x core DSP along with a video encoder and decoder to the hardware on the AM387x. Additionally, OEMs or ODMs that have used the AM387x or DM814x processors and find a need for a faster ARM and/or DSP core performance could scale up to the software-compatible AM389x or TMS320DM816x devices with higher core speeds.
Programmability is provided by an ARM Cortex-A8 RISC CPU with Neon extension. The ARM processor lets developers keep control functions separate from algorithms programmed on coprocessors, thus reducing the complexity of the system software. The ARM Cortex-A8 32-bit RISC core with Neon floating-point extension includes: 32KB of instruction cache; 32KB of data cache; 512KB of L2 cache; 48KB of boot ROM; and 64KB of RAM.
The AM387x Sitara ARM processors also include an SGX530 3D graphics engine to off-load many graphics processing tasks from the ARM core, making more ARM MIPS available for common processing tasks on algorithms. Additionally, the AM387x processor has a complete set of development tools for the ARM which include C compilers and a Microsoft Windows debugger interface for visibility into source code execution.
