A 600MHzlA-32 microprocessor with enhanced data streaming for graphics and video

摘要

This Intel architecture microprocessor (Pentium III) implements 70 additional instructions to further accelerate the performance of data-streaming applications including 3D graphics and video encode/decode. This processor is enhanced by additionof these instructions along with circuit improvements for higher clock frequency [2]. The 10.17×12.10mm{sup}2 die contains 9.5M transistors and is in a CMOS 5-layer metal 0.25μ process in an OLGA package with C4 interconnect technology. It has anoperating range of 1.4V to 2.2V and is currently running up to 600MHz.The Pentium III processor implements 53 new instructions and an 8-entry register file to support a new packed floating point data type. Each architectural register is 128b wide with four independent single-precision elements packed in parallel.Floating-point arithmetic modes are supported for full compliance with IEEE 754 standard in rounding, and for streamlining multimedia applications where under-flowed results are forced to a zero result.
