Perhaps you can help by trying to implement them in VHDL (after all, one of the key requirements for a task being non-draft is multiple implementations, preferably in widely different languages) but be aware that this may be difficult because of lack of definition of ... Basic resizing and rounding resize is a VHDL library function that can be used as a rounding and saturation primitive for adjusting the size of fixed-point operands Input: a fixed-point operand (arg), a left and a right index bound and two additional arguments that specify the rounding (underflow) and saturation (overflow) mechanisms Synthesis 107 UG901 (v2019.1) June 12, 2019 www.xilinx.com Chapter 4:HDL Coding Techniques. -- For static convergent rounding, the pattern detector can be used -- to detect the midpoint case.

The effect is to round to the nearest remaining even value. This is also called convergent rounding. Using the example from above we see the convergent rounded values are 0110and 1010which add to zero.The digit recurrence non restoring division algorithm is designed using high speed subtractor and adder and implemented on FPGA xc3s100e-5vq100. Binary division is basically a procedure to determine how many times the divisor D divides the dividend B thus resulting in the quotient Q. At each step in the process the divisor D either divides B into a group of bits or it does not. The divisor ... There appears to be support for symmetric rounding in the "Math Functions -> Multiplier" core, but it was grayed out, and nothing I did seemed to enable it. If you examine the downloadable code examples from UG901, you'll see examples of RTL (vhdl & verilog) that implement convergent rounding to odd or even values in the DSP48.
