1.3 Description

The 66AK2Hxx platform combines the quad ARM Cortex-A15 processor with up to eight TMS320C66x

high-performance DSPs using the KeyStone II architecture. The 66AK2H14/12/06 device provides up to

5.6 GHz of ARM and 9.6 GHz of DSP processing coupled with security, packet processing, and Ethernet

switching at lower power than multichip solutions. The 66AK2H14/12/06 device is optimal for embedded

infrastructure applications like cloud computing, media processing, high-performance computing,

transcoding, security, gaming, analytics, and virtual desktop.

The C66x core combines fixed-point and floating-point computational capability in the processor without

sacrificing speed, size, or power consumption. The raw computational performance is 38.4 GMACS/core

and 19.2 Gflops/core (@ 1.2 GHz operating frequency). The C66x is also 100% backward compatible with

software for C64x+ devices. The C66x core incorporates 90 new instructions targeted for floating point

(FPi) and vector math oriented (VPi) processing.

The 66AK2H14/12/06 device has a complete set of development tools that includes: a C compiler, an

assembly optimizer to simplify programming and scheduling, and a Windows? debugger interface for

visibility into source code execution.
