Ignorant question:
Given the ridiculous number of transistors and so on we can use in CPUs and GPUs nowadays how feasible is a relatively huge trig lookup table burned into rom?
- zokier 3y agoThere is huge number of 64bit floats and huge portion of those are between 0..pi/2.
- bigbillheck 3y agoSeems like a terrible idea on latency grounds alone.
- aidenn0 3y agoA lookup table (for any function) that covered all values between 0 and 1 in single precision, would be ~4GB; there are approximately 1B values between 0 and 1, and the result of each value is 4 bytes. Such a table for double-precision would be much, much larger.
