1.3 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.  
HyperLink provides a 50-Gbaud chip-level interconnect that allows SoCs to work in tandem. Its low-protocol  
overhead and high throughput make HyperLink an ideal interface for chip-to-chip interconnections. Working with  
Multicore Navigator, HyperLink dispatches tasks to tandem devices transparently and executes tasks as if they are  
running on local resources.  
1.4 Device Description  
The TMS320C6678 DSP is a highest-performance fixed/floating-point DSP that is based on TI's KeyStone multicore  
architecture. Incorporating the new and innovative C66x DSP core, this device can run at a core speed of up to  
1.4 GHz. For developers of a broad range of applications, such as mission-critical systems, medical imaging, test and  
automation, and other applications requiring high performance, TI's TMS320C6678 DSP offers 11.2 GHz  
cumulative DSP and enables a platform that is power-efficient and easy to use. In addition, it is fully backward  
compatible with all existing C6000 family fixed and floating point DSPs.  
TI's KeyStone architecture provides a programmable platform integrating various subsystems (C66x cores, memory  
subsystem, peripherals, and accelerators) and uses several innovative components and techniques to maximize  
intra-device and inter-device communication that allows the various DSP resources to operate efficiently and  
seamlessly. Central to this architecture are key components such as Multicore Navigator that allows for efficient data  
management between the various device components. The TeraNet is a non-blocking switch fabric enabling fast and  
contention-free internal data movement. The multicore shared memory controller allows access to shared and  
external memory directly without drawing from switch fabric capacity.
