The AN/UYK-44 CPU had built in trig instructions, including a single instruction rectangularpolar conversion feature. It use an odd floating point format where the exponents were base
16 instead of base 2. And for extra fast angular stuff, it supported a "BAM" type: binary angular measurement, where 0-360 degrees was mapped to 0-MAXUNSIGNED. That let you do a lot of angular calculations very quickly using integer ALU operations.And it was definitely not BGA. :)
It was a whole rack of SEMs: approx 2x5" "DIMM" style modules (that were on ceramic substrates instead of fibergalss, IIRC).
All the computing power of an 8086/8087 combination, but neatly packaged in a cabinent the size of a small refridgerator with a
5-digit pricetag and requring hundreds of watts of power.Oh, and the software tools...
