RTX-51 is a runtime library that, together with C51, allows real-time systems to
be implemented for all processors of the 8051 family (e.g., 8051, 8052, 80515,
etc.), except for the 8?C751 and 8?C752.
RTX-251 extends the functionality of the RTX-51 to the new intel MCSÒ 251
family of processors. It is available as a set of runtime libraries supporting the
binary and the source mode to be used with the C251.
Verilog HDL: Magnitude
For a vector (a,b), the magnitude representation is the following:
A common approach to implementing these arithmetic functions is to use the Coordinate Rotation Digital Computer (CORDIC) algorithm. The CORDIC algorithm calculates the trigonometric functions of sine, cosine, magnitude, and phase using an iterative process. It is made up of a series of micro-rotations of the vector by a set of predetermined constants, which are powers of two. Using binary arithmetic, this algorithm essentially replaces multipliers with shift and add operations. In a Stratix™ device, it is possible to calculate some of these arithmetic functions directly, without having to implement the CORDIC algorithm.
