These FPU's have a high failure rate :( like 50% of them :roll:
Meanwhile.. just soldered this up...

What is FMUL:Brand?
No idea, I didn't write that app.
I know. I thought it said something in the read me but I had a read myself and it was very sparse. Maybe "Function Multiply", but "Brand" I have no idea?
"BRAND" comes up loads of times, I don't know what it means. https://www.exxosforum.co.uk/forum/viewt ... 00&p=19330DoG wrote: 17 Jul 2020 18:56 I know. I thought it said something in the read me but I had a read myself and it was very sparse. Maybe "Function Multiply", but "Brand" I have no idea?
More precisely: brand = binary data. drand = unit random values. erand = exponentiated random values. The test in question ("FMUL") multiplies the values from these random tables and checks the results.Three large random tables are used. One provides unit double precision values in
the range (-1.0 -> +1.0), another raises unit random values to 2^+/-N where N is
a random in the range (-128 -> +127), another uses pure random binary data which
may include denormalised or NaN values. These tables are used as source data for
many of the tests.
