• First sentence "The Summed Parallel Infinite Impulse Response (SPIIR) pipeline, first implemented by Shaun Hooper" not very appropriate. The SPIIR method has been developed by a group of people and is still being improved. SPIIR "pipeline" employs the SPIIR method and other components. Shaun implemented the first version of SPIIR filtering in the pipeline. Many people contribute to this pipeline.

• label all equations ? easier to refer to.

• work explained first and then span ? easier to understand.

• Sec. 3.2 number of filters F is number of templates

• Sec. 3.3 O(ST/P) not clear what is T

• you are right, the complexity for postcoh is ~ D^3 instead of D^4.

The proposal is due on UWA's LMS at 12:00+08:00 2020-04-20

The estimate of O(2 * N_d^3 * N_m * N_p) from Qi Chu's PhD thesis wasn't updated in this optimization paper. We need to check what the runtime complexity is, and determine the per-thread complexity.

• More thoroughly read optimization paper
• Begin reading through the code in postcoh
• Generate call graph in postcoh
• Write out the per-thread math
• Determine runtime complexity

I don't know an awful lot about it, so its worth researching to nail it down.
