A computing system is specifically adapted for the performance of vector operations. A computing system takes two vector streams and orders the elements of those vector streams into a single ordered vector stream. Each vector stream is received in a different receiver register with each vector being...
To consistently use the instructions generated by vector intrinsic procedures, users need to make all existing Vector Multimedia Extension (VMX) and Vector Scalar Extension (VSX) load and store intrinsic procedures operate on the vectors in registers in
