Tensilica’s Diamond Standard Series processor family of synthesizable cores range from the industry's smallest 32-bit, ultra-low power, cache-less RISC controller to the industry’s highest performance licensable DSP and most popular audio processor and an exciting video processor family. The Diamond Standard family covers the broadest range of performance of any embedded computing architecture and have been proven in our customers designs.
The Diamond Standard processor family is based on Tensilica’s highly efficient Xtensa configurable and extensible processor architecture, proven in hundreds of SOC (system-on-chip) designs. Therefore, it’s easy for designers to bridge to Tensilica’s Xtensa processor product line if additional customization is required.
Diamond Standard Controllers and CPUs
The Diamond Series’ wide range of processor cores provides the most advanced, versatile, and highest performance computing architecture in the embedded processor industry, making them ideal for applications ranging from low-power handsets to high-performance communications. The Diamond Standard processors are supported by an optimized set of Diamond Standard software tools and a wide range of industry infrastructure partners, ranging from top-tier ASIC and foundry partners to companies that provide operating system support, co-verification, in-circuit emulation, EDA tools, and more.
The Diamond Standard 106Micro is now available for FPGA designers who use Synplicity’s Synplify Pro and Synplify Premier software. Click here for more information.
