This work introduces a new floating point representation for complex numbers (“Complex floating point”), and compares it to the floating point representation defined in the IEEE 754 standard, with a reference to the common DSP fixed point representation. The new suggested representation uses fewer bits than the IEEE 754, while keeping the same dynamic range and precision. A number of common DSP building blocks have been implemented. Results show that for the new representation, the ASIC silicon… CONTINUE READING
