Being the SIMD fanatic that I am, a few years ago I did the PowerPC Altivec and ARM NEON port for the Eigen linear algebra library, one of the best and most popular libraries -and most ported. Recently I thought it would be a good idea to extend ... [More] both ports to 64-bit, and it would also help me with the SIMD book, using VSX in one case and ARMv8 NEON (or Advanced SIMD as ARM likes to call it) in the latter. ARMv8 hardware is a bit scarce at the moment, so I thought I'd start with VSX. Being in Debian, I have access to a number of porterboxes in several architectures, and luckily one of those was a Power7 (with VSX) running ppc64. So I started the porting -or rather extending the code- to use VSX in the 64-bit doubles case. Unluckily, I could not test anything because Debian kernels do not have VSX enabled in wheezy -which is what the porterbox is running and enabling it is a non-option(#758620). So, running VSX code would turn out to be quite hard. [Less]

Ok, took a while but I got the final word about this and can announce that the sponsor who donated 500 EUR to the Indiegogo campaign was ARM itself! I have to thank my friends at ARM@Cambridge and especially Dr Monika Biddulph, General Manager ... [More] , Partner Enablement Group at ARM. When the book goes to print you can be sure it will include "Sponsored by ARM" somewhere! :) Also a friendly reminder that even if the campaign is over, I still welcome the support in the form of preorders/sponsorships.

Finally. Apologies for the delay, but it's been a busy month. This time I will hold true to my word and upload a PDF for people to see (attached to this page). So, what's new? Here is a list of things done: * Finished ALL addition/subtraction related ... [More] instructions for all engines and major derivatives (SSE*/AVX, VMX/VSX, NEON/armv8 NEON). With diagrams (these were the reasons it has taken so long). * Reorganized the structure (split the book into Parts I/II, the instruction index will be in Part II, Part I will carry the design analysis of each SIMD engine. * Added an TOC/index. * So far, with just Addition/Subtraction Chapter and the rest empty sections, it has reached 175 pages (B5, again I'm not fixed on the size, it might actually change)! My estimate is that the whole book will surpass 800 pages with everything included. TODO: [Less]

From the Indiegogo page: https://www.indiegogo.com/projects/simd-engines-comparative-reference-guide/x/4966960#activity Added titlepage (simple, but will do the job) Reorganized ALL instructions to include both unsigned/signed in the same ... [More] entity Added Saturated Addition, Subtraction and Saturated Subtraction Added ARMv8 NEON instructions taken from ARM infocenter draft Fixed some instructions (added 64-bit arithmetic for NEON) Added some special addition/subtraction, like add/sub with carry(vmx/vsx), addsub(SSE3/AVX) Added some in-vector sum additions, sum reductions but no descriptions yet Added diagram for 8-bit addition/subtraction (still need lots more). Removed VMX128, couldn't find enough information, an email to some IBM toolchain developers was left unanswered, so I guess noone really will really care if that engine is left out, if enough people insist on it, please also be kind enough to provide some documentation on it.
