This is a novel integer divider using r4 division by recurrence. The

Although this version does not contain scaling, it could do this, if
|
|
needed. Moreover, a higher radix or overlapped radix can be done
|
|
easily to expand the the size. Also, the implementations here are
|
|
initially unsigned but hope to expand for signed, which should be
|
|
easy.

|
There are two types of tests in this directory within each testbench.
|
|
One tests for 32-bits and the other 64-bits:
|
|
|
|
int32div.do and int64div.do = test individual vector for debugging
|
|
|
|
iter32.do and iter64.do = do not use any waveform generation and just
|
|
output lots of tests
