Instruction Systolic Array

The BitGrid is based on the idea of data flowing through a grid of instructions. The logical inverse of this situation is to have the data remain in place, while instructions to modify it flow past it... this is the Instruction Systolic Array.

The idea is intriguing because it offers a way to get the benefits of the systolic array without having to have all of the bandwidth necessary to update all of the cells at once. The web site is well thought out and informative as well. I like the illustration of the matrix multiply using their concept.

There are a lot of architectures that got skipped along the way to our current crop of FPGA and other programmable logic circuits. I think that the systolic array warrants further consideration as well as the BitGrid.
