The paper describes the development and definition of Intel’s new Internet Streaming SIMD Extensions introduced on the PentiumÒ III processor. The extensions are divided into three categories: SIMD-FP, New Media, and Streaming Memory instructions. The new extensions accelerate the 3D geometry pipeline by nearly 2x that of the previous-generation processor while enabling new applications, such as real-time MPEG-2 encode. The Pentium III processor implementations achieved the desired goal at a modest 10% increase in die size. The definition achieved the short-term goal while still providing the performance scalability needed for future implementations.
