These functions work on two parameters u and 24 v, and copy the result to the first parameter u. This 25 is also the reason that they are suffixed with _on_help. 26 27 The vec_* functions are called through either these 28 functions or those in sc_nbfriends.cpp. The functions in 29 sc_nbfriends.cpp perform their work on two inputs u and v, 30 and return the result object. 31 32 Original Author: Ali Dasdan, Synopsys, Inc. 33 34 *****************************************************************************/ 35 36 /***************************************************************************** 37 38 MODIFICATION LOG - modifiers, enter your name, affiliation, date and 39 changes you are making here. 40 41 Name, Affiliation, Date: 42 Description of Modification: 43 44 *****************************************************************************/ 45 46 // $Log: sc_nbexterns.h,v $ 47 // Revision 1.2 2011/02/18 20:19:15 acg 48 // Andy Goodrich: updating Copyright notice. 49 // 50 // Revision 1.1.1.1 2006/12/15 20:20:05 acg 51 // SystemC 2.3 52 // 53 // Revision 1.3 2006/01/13 18:49:32 acg 54 // Added $Log command so that CVS check in comments are reproduced in the 55 // source. 56 // 57 58 #ifndef SC_NBEXTERNS_H 59 #define SC_NBEXTERNS_H 60 61 62 #include "sysc/datatypes/int/sc_nbutils.h" 63 64 65 namespace sc_dt 66 { 67 68 extern 69 void add_on_help(small_type &us, 70 int unb, int und, sc_digit *ud, 71 small_type vs, 72 int vnb, int vnd, const sc_digit *vd); 73 74 extern 75 void mul_on_help_signed(small_type &us, 76 int unb, int und, sc_digit *ud, 77 int vnb, int vnd, const sc_digit *vd); 78 79 void div_on_help_signed(small_type &us, 80 int unb, int und, sc_digit *ud, 81 int vnb, int vnd, const sc_digit *vd); 82 83 extern 84 void mod_on_help_signed(small_type &us, 85 int unb, int und, sc_digit *ud, 86 int vnb, int vnd, const sc_digit *vd); 87 88 extern 89 void mul_on_help_unsigned(small_type &us, 90 int unb, int und, sc_digit *ud, 91 int vnb, int vnd, const sc_digit *vd); 92 93 void div_on_help_unsigned(small_type &us, 94 int unb, int und, sc_digit *ud, 95 int vnb, int vnd, const sc_digit *vd); 96 97 extern 98 void mod_on_help_unsigned(small_type &us, 99 int unb, int und, sc_digit *ud, 100 int vnb, int vnd, const sc_digit *vd); 101 102 extern 103 void and_on_help(small_type us, 104 int unb, int und, sc_digit *ud, 105 small_type vs, 106 int vnb, int vnd, const sc_digit *vd); 107 108 extern 109 void or_on_help(small_type us, 110 int unb, int und, sc_digit *ud, 111 small_type vs, 112 int vnb, int vnd, const sc_digit *vd); 113 114 extern 115 void xor_on_help(small_type us, 116 int unb, int und, sc_digit *ud, 117 small_type vs, 118 int vnb, int vnd, const sc_digit *vd); 119 120 } // namespace sc_dt 121 122 123 #endif 124
