Matrix Multiply
Start systolic matrix element multiply, the source register is the location of the register source matrix, the product is written into the destination register. Refer to the section on matrix multiplies.
Code/Case: 54
The flags reflect the final multiply/accumulate operation:
Flags
Z – set if the result is zero
N – set if the result is negative
C – represents carry out of the adder
Register Usage
Refer to the discussion of multiply/accumulate
DSP matrix multiples only work in the lower 4K of DSP RAM. The DSP matrix register can only point to memory locations in the first 4K of DSP RAM. Only address lines 2-11 are programmable; the rest of the matrix address is hard-wired to $F1Bxxx.
