Current focus: MXINT8 and interactions with FP32 (IEEE 754)

MXINT8 Status Table

function	C++ model	Verilog	Testbench
add (vec-vec)	✅	✅	✏️
multiply (scalar-vec)	❌	❌	❌
multiply (vec-vec)	❌	❌	❌
dot product (vector)	✅	✅	✅
broadcast (scalar -> vector)	😐	✅	✅
conversion vector(fp32 -> mxint8)	❌	❌	❌
conversion vector(mxint8 -> fp32)	❌	❌	❌
sum (vector -> scalar)	✅	✅	✅
negate (vector -> vector)	😐	✅	✅

(😐=NA, 🤔=UNSURE, ✏️=WIP, ❌=TODO, ✅=DONE)

For vector add, subtract, multiply, divide, inspiration can be taken from the scalar equivalents in FP32 implemented here in C++.
