The user selects the numeric format and transformation to be performed (Rectangular-To-Polar or Polar-To-Rectangular), and the operation is performed on the data presented to the inputs on the next clock. The transformed result is then available at the outputs 22 clock cycles later, with new out- put data available every 20ns with a 40 MHz clock. All input and output data ports are registered, with input clock enables and asynchronous high-impedance output enables to sim- plify connections to system buses. When executing a Rectangular-To-Polar conversion, the input ports accept 16-bit Rectangular coordinate words, and the out- put ports generate 16-bit magnitude and 16-bit phase data. The user selects either two’s complement or sign-and-magnitude Cartesian data format. Polar magnitude data are always in magnitude format only. Since the phase angle word is modulo 2 π, it may be regarded as either unsigned or two’s complement format (Tables 1 and 2). In Polar-To-Rectangular mode, the input ports accept 16-bit Polar magnitude and 32-bit phase data, and the output ports produce 16-bit Rectangular data words. Again, the user selects between two’s complement or sign-and-magnitude Cartesian data format. |
