AC DataTypes Plus

this repo is a fork of mentor's Algorithmic C Datatype providing more feature and Eigen library compatibility.

TODO :

as you wish

CHANGES :

• add width to ac_datatype
• ac_base_type become base class of ac_int,ac_fixed,ac_float,ac_channel,ac_complex
• add is_ac_type to detect a type is an ac_type
• add is_ac_basic_type to detect a class is ac_int,ac_fixed or ac_channel,ac_complex of these two types
• add ac_hex_string ac_hex_wstring ac_hex_u16string ac_hex_u32string
• add ac_bin_string ac_bin_wstring ac_bin_u16string ac_bin_u32string (any of these strings can convert to ac_basic_type directly. any of these string can be convert from ac_base_type directly )
• add _bin _hex literal to 4 types of strings
• add math lib porting
• support eigen

Examples :

ac_bin_string

auto bin_str = "1001_0110_b"_bin;//'-','_','b',' ' would be ignored
ac_int<8,false> data = bin_str;

cout << bin_str << endl;
cout << data << endl;

data = 42;
bin_str = data;

cout << bin_str << endl;
cout << data << endl;

ac_hex_string

auto bin_str = "0x55AA"_hex;//'-','_',' ','h','H',"0x" would be ignored
ac_int<16,false> data = bin_str;

cout << bin_str << endl;
cout << data << endl;

data = 42;
bin_str = data;

cout << bin_str << endl;
cout << data << endl;

ac_convert

auto ac_int<16,false> data;
auto bits = ac_convert::to_bitset(data);

cout << data << endl << bits << endl;

ac_math

auto ac_fixed<16,1,true> data = 0.5;

cout << sqrt(data) << endl;

type detect

cout << is_ac_type<int8>::value << endl;   // true
cout << is_ac_type<ac_float<16,1,8>>::value << endl; // true
cout << is_ac_type<int8_t>::value << endl; // false
cout << is_ac_type<ac_channel<int>>::value << endl; // true
cout << is_ac_type<ac_channel<int8_t>>::value << endl; // true


cout << is_ac_basic_type<int8>::value << endl; // true
cout << is_ac_basic_type<int8_t>::value << endl; // false
cout << is_ac_basic_type<ac_float<16,1,8>>::value << endl; // false
cout << is_ac_basic_type<ac_channel<int8>>::value << endl; // true
cout << is_ac_basic_type<ac_channel<int8_t>>::value << endl; // false
