Fixed-point representation
WebThe range of a U(a,b) representation is from 0 to (2N −1)/2b =2a −2−b. For example, the 8-bit unsigned fixed-point rational representation U(6,2) has the form b 5b 4b 3b 2b 1b 0.b−1b−2, where bit bk has a weight of 2k. Note that since b = 2 the binary point is to the left of the second bit from the right

WebNov 23, 2016 · \$\begingroup\$ "Fixed point" is a mapping of a mathematical concept to its representation in logic signals. I cannot see why referencing the same VHDL-type would be a drawback for designs using the same mapping. It makes IP interoperable. You are still free to define whatever you want, if you are better off with a non-standard representation ... WebOct 7, 2003 · Fixed-point math typically takes the form of a larger integer number, for instance 16 bits, where the most significant eight bits are the integer part and the least significant eight bits are the fractional part. Through the simple use of integer operations, the math can be efficiently performed with very little loss of accuracy.
