U.S. Patent 9,513,920 - Computer Processor Employing Split-Stream Encoding

This patent is for the split-stream method of encoding that permits Mill CPUs to decode extremely wide instructions (those with many independent operations in each instruction) using a compact and flexible variable-length encoding that is also fast to decode. The stream of instructions that is the program being executed is split into two streams of half-instructions that are stored separately in memory but are processed in lock-step by the CPU decoder. Because wide fixed length instruction encodings use an impractical amount of cache and memory, and variable-length encodings take time polynomial in the width, instruction decode on legacy CPUs is limited to eight operations per cycle or fewer; Mill split-stream encoding supports instruction widths of over thirty operations decoded per cycle. In addition, split-stream permits doubling the amount of instruction cache with no clock or pipeline penalty.

General Questions

Fri, 28 Mar 2014 04:03:02 +0000

Q: What does NYF stand for? Stands for Not Yet Filed - as used here it refers to a patent or patents that are Not Yet Filed. Questions about patentable mechanisms that are NYF cannot be answered without an NDA due to USPTO rules.

Q: Why no PDF slides? Publishing PDF slides (instead of .pptx) would make them available to more people. A: Unfortunately PDF format doesn’t support the animations, and without those the slides are pretty useless. We looked into creating a completely different presentation without the animations, but decided we don’t have the bandwidth, and the need for a static format was better served by white papers, of which we have a few in process. We had been using OpenOffice (and tried LibreOffice) but found both useless because of bugs in the animation on some platforms and the generally limited support for animation creation, and so settled on MSOffice as the best of the choices.

Introduction to the Mill CPU Programming Model

Fri, 07 Feb 2014 10:48:53 +0000

The Mill is a new CPU architecture designed for very high single-thread performance within a very small power envelope.

The Mill has a 10x single-thread power/performance gain over conventional out-of-order (OoO) superscalar architectures, yet runs the same programs without rewrite.

The Mill is an extremely-wide-issue, statically scheduled design with exposed pipeline. High-end Mills can decode, issue, and execute over thirty MIMD operations per cycle, each cycle.

The Mill architecture is able to pipeline and vectorise almost all loops, including while loops and loops containing calls and flow control.
