Abstract :
The AltiVecTM technology is an extension to the PowerPC architectureTM which provides new computational and storage operations for handling vectors of various data lengths and data types. The first implementation using this technology is a low-cost, low-power processor based on the acclaimed PowerPC 750TM microprocessor. This paper describes the microarchitecture and design of the vector arithmetic unit of this implementation
