For the unsigned integer format used in the MMDVSQ's square root calculation, an
u(nsigned)Qm.n notation requires m+n bits (m+n = 32) for the input radicand. An uQm.n
format produces an uQ(m/2).(n/2) square root. As examples, consider the following
tables involving the square root of 2 and square root of “pi” calculations. As expected, as
the number of fractional bits (n) increases, the error between the calculated square root
and the “actual” result decreases.

The application of the Q notation for square root calculations provides a powerful
extension for these types of fractional numeric computations using fixed-point integer
processing hardware.

6.5.2 Execution times

The MMDVSQ module includes early termination logic to finish both divide and square
root calculations as quickly as possible, based on the magnitude of the input operand.
Accordingly, the execution time for the calculations is data dependent as defined in

and

. In this context, the execution time is defined from the register write to

initiate the calculation until the result register has been updated and available to read.
Stated differently, it represents the time CSR[BUSY] is asserted for a given calculation.
In the following two tables, “x” signals a bit with a don’t care value.
