14-implementing FIR filter 1b - Emulation-AIE build crashes

[nielsvanetten]

When building Emulation-AIE for the graph of 1b, it crashes: make[1]: Waiting for unfinished jobs.... make[1]: [25_0.elfgen.Makefile:14: 25_0] Error 5 make[1]: [24_1.elfgen.Makefile:14: 24_1] Error 5 make[1]: [24_0.elfgen.Makefile:14: 24_0] Error 5 aiecompiler 77-4608

Emulation-SW does work though.

In README.md: "In Part 1, we have focused only on functional verification using Emulation-SW. "

Part1 is not expected to be used with Emulation-AIE as it is intended to show the preliminary steps in the development process. Please see Part2a and Part2b to use Emulation-AIE.

If it is really required to run Emulation-AIE on Part1b, please make the following edits to kernel.cpp:

WAS:

for (auto i = 1; i < 12; i++) {
        coeff = aie::load_v<8>(&C[8 * i]);
        acc = aie::mac(acc, coeff, xreg[i + 4]); // xreg[] is not a compile-time constant
        ...
}

IS:

for (auto i = 1; i < 12; i++) {
        coeff = aie::load_v<8>(&C[8 * i]);
                float xval = xreg[i + 4];
        acc = aie::mac(acc, coeff, xval); // xval is a compile-time constant
        ...
}

thank you !
