can this be simplified? (blu->ary->mem to blu->mem)

This is a conceptual schematic.
I don't like the part with analyzer that creates an array which is then converted to mem. The project will contain approx. 1500 mem points, some of them with very long arrays.
Question - can this be simplified,so that the blue stream is converted directly into mem, and only one copy of analyzer runs somewhere, to redistribute data across all processors to corresponding mems?
*
And second question, when we speak about mems. How to resample (downsample) stream data contained in mem?
There will be multiple situations, where filter sends a stream at certain sample rate. Let say 10 seconds at 44.1k, which gives 441k of samples). When converting from mem to array - I'd like to get a resampled array, let say at 400Hz, which means that the array will be 4k of samples long.
Green primitive can do the job, but I'm sure mem operation will be faster. Especially with over 1000 operations.
BTW, which lowpass filter (among these on FS forum) is best to use prior to downsampling, to block freqs above the nyquist limit? (in above example - 200Hz or less)
