Features and Benefits

P6 Dynamic Execution Micro-architecture

Includes multiple branch prediction, data flow analysis, and speculative execution.
Multiple branch prediction Predicts program execution through multiple branches, accelerating the flow of work to the processor
Data flow analysis Creates an optimized, reordered schedule of instructions by analyzing data dependencies between instructions
Speculative execution Carries out instruction execution speculatively, ensuring superscalar execution units remain busy, boosting overall performance
Dual Independent Bus (DIB) Frees system bus from cache traffic, providing higher overall system bandwidth, improved system performance and scalability
Non-Blocking Level 1 Cache Fast access to the recently used data, increasing the overall performance of the system
to top of page 256 KB Level 2 Advanced Transfer Cache (some versions) Higher data bandwidth interface between the level 2 cache and the processor core reduces latency interface to cache data
Non-Blocking Level 2 Cache (some versions) Improves performance over cache-on-motherboard solutions with dedicated 64-bit cache bus. Also reduces the average memory access time by providing fast access to recently used instructions and data
Advanced System Buffering (some versions) Increases utilization of the available bandwidth on the 100 and 133 MHz system bus
Internet Streaming SIMD Extensions Higher resolution images viewed and manipulated, high quality audio, MPEG2 video, and simultaneous MPEG2 encoding and decoding, reduced CPU utilization for speech recognition, as well as higher accuracy and faster response times
Up to 133 MHz System Bus Increases bandwidth availability; enables low-cost, two-way symmetric multiprocessing, providing performance boost for multi-tasking operating systems and multi-threaded applications
