Currently, the hardware is complete while the software (firmware) is on its early version. Current implementation
9-
provides corret results for test matrix multiplications.
8+
Finally implemented the interrupt function after load and matmul is finished. I also made the main.c file a little bit cleaner
9+
by using header files for interrupt and XGPIO initialization and the matrix references.

For now, the firmware code includes only the backbone of the planned finished code. I have included an interrupt
12-
signal to be sent from the PL to PS after finishing matrix multiplication (23 clock cycles) and/or loading registers (8 clock cycles) but
13-
had not yet included it on the firmware. I'll do it as soon as possible. :)

Next version would be adding new memory spaces for additional matrices in the PL fabric which would allow us to write
12+
multiple matrices then switch to whatever matrix we want for matrix multiplication by specifying which matrices to load
13+
to the registers.

Note: Github Repo would not be updated for every edit on files but only for major updates only.
16-
Next update would be the completed version of the systolic array software and hardware.
15+
I am also planning to add some features to specify if the matrix to be written on to the FPGA is a weight or input matrix
16+
so we can "automatically" transpose the matrix. As of now, the matrix we have is transposed by default.
