KeyStone Architecture
TI’s KeyStone Multicore Architecture provides a high performance structure for integrating RISC and DSP
cores with application specific coprocessors and I/O. KeyStone is the first of its kind that provides
adequate internal bandwidth for nonblocking access to all processing cores, peripherals, coprocessors,
and I/O. This is achieved with four main hardware elements: Multicore Navigator, TeraNet, Multicore
Shared Memory Controller, and HyperLink.
Multicore Navigator is an innovative packet-based manager that controls 8192 queues. When tasks are
allocated to the queues, Multicore Navigator provides hardware-accelerated dispatch that directs tasks to
the appropriate available hardware. The packet-based system on a chip (SoC) uses the two Tbps capacity
of the TeraNet switched central resource to move packets. The Multicore Shared Memory Controller
enables processing cores to access shared memory directly without drawing from TeraNet’s capacity, so
packet movement cannot be blocked by memory access.
