LONDON – Imagination Technologies Group plc has signed an agreement with Forte Design Systems Inc. to extend its use of CellMath Optimizer EDA tool with current generation PowerVR graphics cores and to allow Imagination to distribute and support the design software.
The companies did not disclose plans for future generation graphics cores.
CellMath was originally developed by a company called Arithmatica subsequently acquired by Forte. CellMath embodies novel mathematical encodings that can therefore produce transistor- and energy-efficient silicon math units. Nvidia, Qualcomm, Toshiba and Xilinx have all been revealed as direct licensees of the CellMath technology.
Imagination (Kings Langley, England) uses Forte's CellMath Optimizer to help enable its licensing partners to optimize silicon efficiency and performance in their target process technology. As part of this latest agreement, Imagination will manage all distribution and support of the Forte (San Jose, Calif.) tools for all its licensees.
Forte's CellMath Designer datapath synthesis and CellMath IP software enables designers working at the register transfer level (RTL) to reduce area, improve performance and lower power consumption, Imagination claimed.
The CellMath floating point IP library contains math units that can be configured for bit widths or rounding modes. Floating point implementations can be configured with IEEE precision or with reduced precision for graphics or other applications where smaller, faster implementations are required. Available functions include adders, multipliers, dividers, square root, dot-product, reciprocal square root, exponential and logarithm. The library also contains multi-function parts that can produce any of these floating point functions using shared resources to reduce the combined area.
"Forte's CellMath tools and IP are a small but significant part of our PowerVR SGX and VGX IP deliverables," said Martin Ashton, vice president of engineering for PowerVR visual IP cores at Imagination, in a statement. "The change in licensing and responsibilities will enable us to provide a better IP delivery and support service as part of our commitment to provide a one-stop total solution for SoC IP for our customers."
"Imagination Technologies has proven that high-quality design IP is an essential part of SoC design," adds Sean Dart, president and chief executive officer of Forte Design Systems, in the same statement.
