Tool speeds ASIP design by five times

The tool enables users to explore multiple processor architecture alternatives in minutes. Using a single input specification in the nML language, the ASIP Designer automatically generates both the synthesisable RTL of the processor as well as an SDK that includes an optimising C/C++ compiler, instruction set simulator, linker, assembler, software debugger and profiler. This ensures consistency of the hardware and the SDK at all stages of the design process. The patented compiler generation technology includes an LLVM compiler front-end and support for the OpenCL kernel language. Immediate availability of the compiler enables users to run their C, C++ and OpenCL application code on the automatically-generated instruction-set simulator as soon as the nML-based description is available. With this unique ‘compiler-in the-loop’ approach as well as the extensive profiling capabilities of the debugger, ASIP Designer users can rapidly analyse and explore ASIP architectures and instruction sets to find the optimal power and performance design points for the target application.

ASIP Designer also automatically generates a SystemC-based transaction-level model, allowing pre-silicon software development using virtual prototypes such as those designed with Synopsys' Virtualizer tool set. A common and easy-to-use flow from RTL generation to instantiation in the HAPS FPGA-based prototyping system, in addition to the automatic generation of JTAG-based on-chip debug logic, enables designers to integrate the ASIP into the SoC design and connect the prototype with real-world I/Os to validate the hardware-software integration.

A wide range of example ASIP designs for highly differentiated architectures, provided in nML source code, allows designers to quickly start designing their own ASIP that targets their specific application requirements.

"Using Synopsys' ASIP tools we've developed and deployed a full line of highly differentiated AudioSmart products. These products are based on the Conexant Audio Processing Engine, or CAPE, a Conexant-designed DSP," said Saleel Awsare, Vice President and General Manager, Conexant. "Application-specific architecture optimisations make CAPE highly efficient for far-field voice and audio playback processing, and Synopsys' tools assure ease of creation and programmability. By continuing to invest in ASIP tool technology, Synopsys is helping Conexant create market-leading domain-specific products."

"ASIPs offer distinct advantages over standard DSPs and fixed hardware in many data plane and signal processing applications," said John Koeter, Vice President of Marketing for IP and Prototyping, Synopsys. "Synopsys' ASIP Designer tool, built on proven technology used in hundreds of products in the market, helps design teams speed the development of custom processors and programmable accelerators tuned to their specific application. ASIP Designer gives users the ability to explore and optimise processor architectures for the best power, performance and area, giving them a distinct advantage in creating highly differentiated products."
