This 00023 is also the reason that they are suffixed with _on_help. 00024 00025 The vec_* functions are called through either these 00026 functions or those in sc_nbfriends.cpp. The functions in 00027 sc_nbfriends.cpp perform their work on two inputs u and v, 00028 and return the result object. 00029 00030 Original Author: Ali Dasdan, Synopsys, Inc. 00031 00032 *****************************************************************************/ 00033 00034 /***************************************************************************** 00035 00036 MODIFICATION LOG - modifiers, enter your name, affiliation, date and 00037 changes you are making here. 00038 00039 Name, Affiliation, Date: 00040 Description of Modification: 00041 00042 *****************************************************************************/ 00043 00044 // $Log: sc_nbexterns.h,v $ 00045 // Revision 1.1.1.1 2006/12/15 20:31:36 acg 00046 // SystemC 2.2 00047 // 00048 // Revision 1.3 2006/01/13 18:49:32 acg 00049 // Added $Log command so that CVS check in comments are reproduced in the 00050 // source. 00051 // 00052 00053 #ifndef SC_NBEXTERNS_H 00054 #define SC_NBEXTERNS_H 00055 00056 00057 #include "sysc/datatypes/int/sc_nbutils.h" 00058 00059 00060 namespace sc_dt 00061 { 00062 00063 extern 00064 void add_on_help(small_type &us, 00065 int unb, int und, sc_digit *ud, 00066 small_type vs, 00067 int vnb, int vnd, const sc_digit *vd); 00068 00069 extern 00070 void mul_on_help_signed(small_type &us, 00071 int unb, int und, sc_digit *ud, 00072 int vnb, int vnd, const sc_digit *vd); 00073 00074 void div_on_help_signed(small_type &us, 00075 int unb, int und, sc_digit *ud, 00076 int vnb, int vnd, const sc_digit *vd); 00077 00078 extern 00079 void mod_on_help_signed(small_type &us, 00080 int unb, int und, sc_digit *ud, 00081 int vnb, int vnd, const sc_digit *vd); 00082 00083 extern 00084 void mul_on_help_unsigned(small_type &us, 00085 int unb, int und, sc_digit *ud, 00086 int vnb, int vnd, const sc_digit *vd); 00087 00088 void div_on_help_unsigned(small_type &us, 00089 int unb, int und, sc_digit *ud, 00090 int vnb, int vnd, const sc_digit *vd); 00091 00092 extern 00093 void mod_on_help_unsigned(small_type &us, 00094 int unb, int und, sc_digit *ud, 00095 int vnb, int vnd, const sc_digit *vd); 00096 00097 extern 00098 void and_on_help(small_type us, 00099 int unb, int und, sc_digit *ud, 00100 small_type vs, 00101 int vnb, int vnd, const sc_digit *vd); 00102 00103 extern 00104 void or_on_help(small_type us, 00105 int unb, int und, sc_digit *ud, 00106 small_type vs, 00107 int vnb, int vnd, const sc_digit *vd); 00108 00109 extern 00110 void xor_on_help(small_type us, 00111 int unb, int und, sc_digit *ud, 00112 small_type vs, 00113 int vnb, int vnd, const sc_digit *vd); 00114 00115 } // namespace sc_dt 00116 00117 00118 #endif
