March 14, 2012 -- Vivante Corp. today announced that it has worked with Cadence Design Systems, Inc. to qualify the Cadence double data rate (DDR) Memory controller intellectual property (IP) solution for use with Vivante's graphics processing unit (GPU) IP solution.

Vivante's high-performance multicore GPUs are capable of processing massive amounts of data in order to create the most advanced and realistic 3D visual effects on mobile, embedded and home entertainment devices. To render high-quality images, the GPU requires access to external DDR DRAM through a highly optimized, low-latency DDR memory controller.

The collaboration between Cadence and Vivante has created a tightly coupled memory subsystem that maximizes the efficiency between the GPU, memory controller and external DDR memory. Vivante's memory-friendly architecture uses design features such as burst building, request merging, efficient data access, compression, prefetching, smart banking, prediction and much more. These features provide the optimal data flow and memory-access patterns for graphics applications. The Cadence DDR controller works as the interface between the GPU and DDR memory, fine-tuned to perform data and traffic management. This co-optimized solution enables SOC designers to select a proven, performance-enhanced solution ready for mass market deployment.
