Input format for TI C6416 Turbo Coprocessor?
I am getting confused with TI documentation about the format of the
input soft symbols for TI C6416 turbo coprocessor. Assuming I am just feeding hard-decision symbols (to make the argument simpler) into the TCP and the hard-decision symbols are + or - 127 (decimal value), should I having the following values (in hex): +127 = 0x7F (this is using 2's compliment). (Option 1). -127 = 0x81 Or I should have the following values (in hex): +127 = 0x7F (I don't know what is the name of this format). (Option 2). -127 = 0xFF Thanks.
