We use C++ along with Integrated Performance Primitives (IPP) library which is an extensive library of multicore-ready and highly optimized software functions with single instruction multiple data (SIMD) instructions.
The Wildcat Realizm VSU receives graphics commands at full bandwidth from a 16-lane PCI Express interface and processes vertices with an incredible 67 billion floating point operations per second in a powerful SIMD (Single Instruction Multiple Data) array of highly optimized vector processors.
Additional architectural features include 512 KB of on-chip L2 cache, full symmetric multiprocessing (SMP) support, a 64-bit bus interface and a full 128-bit implementation of Motorola's AltiVec[TM] Single Instruction Multiple Data (SIMD) vector processing technology.
Symmetric multiprocessing, which leverages SMP facilities built into Windows NT, Solaris and Linux, is ideal for SIMD (Single Instruction Multiple Data) applications like graphics and imaging because it enables multiple CPUs to work concurrently on the same program thread, symmetric multiprocessing.
