While Accurate MUL is implemented as very resource heavy fully fledged soft float operation, there is theoretically less accurate but very fast "accurate MUL" available. Surprisingly this is not copy pasted PS3 implementation (no need to reach Olympus from Lop Nor this time). While this implementation is assumed to be less accurate | While Accurate MUL is implemented as very resource heavy fully fledged soft float operation, there is theoretically less accurate but very fast "accurate MUL" available. Surprisingly this is not copy pasted PS3 implementation (no need to reach Olympus from Lop Nor this time). While this implementation is assumed to be less accurate, result should be the same as with soft floats. r14 and esi are source floats for operation. So, here it comes: | ||
