Leon: I just did some bencmark testing using LATTIC C and a loop of 70000 multiplies and divides. The test involves inlined 881 code, standard Amiga IEEE libraries, IEEE without coprocessor, and FFP. Part of the speed of the 881 code is due to the small loop used. Part is due to the the pure speed of the 881/882 processor. IEEE no 881 4.20 sec FFP 2.50 sec IEEE Amiga 1.250 sec 881 inline 0.366 sec At nearly 10 times the speed, it would be very desireable to have a compiler switch which would generate 881 requiring code. At twice the speed, it would be desirable to have IEEE double presision library support. This does not cover the need for double presision math for several applications such as Simulations (particularly continuous or mixed type problems. Non-linear optimizations. Dynamic programing. Linear Algebra. Need I go on? >> Gary <<
