WebDec 14, 2008 · In embedded systems, computation time and memory are critical resources. Floating-point calculations require special floating-point units for efficient computation and this translates to processors that are more expensive. For this reason, designers of embedded systems often use fixed-point numbers. WebMatrix-Multiply Engine Calculation. Calculation: A (NxM) * B (MxL) = R (NxL) The calculation is O (N) in time as the design unrolls two levels of inner loop in the matrix multiply. At the innermost level, the design unrolls the dot product as a systolic DSP chain or column. At the next level, the design unrolls and calculates L columns in parallel. orderflow traders club review
