==== Reading ====
* [[SVE2]]
==== SVE2 Demonstration ====
* Code available here: https://github.com/ctyler/sve2-test
* This is an implementation of a very simple program which takes an image file, adjusts the red/green/blue channels of that file, and then writes an output file. Each channel is adjusted by a factor in the range 0.0 to 2.0 (with saturation).
* The image adjustment is performed in the function <code>adjust_channels()</code> in the file <code>adjust_channels.c</code>. There are three implementations:
*# A basic (naive) implementation in C. Although this is a very basic implementation, it is potentially subject to autovectorization.
*# An implementation using inline assembler for SVE2 with strucure loads.
*# An implementation using inline assembler for SVE2 with an interleaved factor table.
*# An implementation using ACLE compile intrinsics.
* The implementation built is dependent on the value of the ADJUST_CHANNEL_IMPLEMENTATION macro.
* The provided Makefile will build four versions of the binary -- one using each of the four implementations -- and it will run through 3 tests with each binary. The tests use the input image file <code>tests/input/bree.jpg</code> (a picture of a cat) and place the output in the files <code>tests/output/bree[1234][abc].jpg</code>. The output files are processed with adjustment factors of 0.5/0.5/0.5, 1.0/1.0/1.0, and 2.0/2.0/2.0.
* '''Please examine, build, and test the code, compare the implementations, and note how it works - there are extensive comments in the code, especially for implementation 2.'''
* Your observations about the code might make a good blog post!
=== Week 8 Deliverables ====
* Continue your blogging
* Include blogging on SVE/SVE
* The second group of blog posts is due on or before this Sunday (November 6, 11:59 pm) and will be marked early next week.
