I receive an integer from an external API, that is actually a fixed point real value, disguised as int for transport compatibility. I need to convert the integer back into it's fixed point representation. I presume I can convert the int to sc_bv. Then, I would expect sc_fixed to have a constructor accepting a sc_bv, and specify the decimal point place through sc_fixed template. Looking through the source, It seem though that sc_fixed cannot be constructed from a sc_bv. The closest thing I see is the char* constructor (pass bits using sc_bv.to_string() ), but I'm pretty sure that converts a decimal string, not a binary string. In short, is there a simple enough way to convert the bits of an integer (in the form of sc_bv) into a real number (say, float) by specifying the fixed point location in the bit vector?

Hi, I have two files. In header file I have two modules `camkii` and `camkii_ring`. The `camkii_ring` contains N number of `camkii` submodule. I thought of using std::vector to instantiate the submodules. See the code below. #ifndef CAMKII_H #define CAMKII_H #include <systemc.h> #include <vector> using namespace std; SC_MODULE(camkii) { sc_in_clk clock; sc_in<double> ca_conc_in; sc_signal<double> v1, v2, v3; void init() { cout << "[Ca] " << ca_conc_in << endl; //cout << sc_get_time_resolution() << endl; } void compute_rate() { // do something } SC_CTOR(camkii) { init(); SC_METHOD(compute_rates); sensitive << clock.pos(); } }; /* * This module is a ring of CamKII holoenzyme. It has total of 6 camkii * holoenzymes. */ SC_MODULE( camkii_ring ) { sc_in_clk clock; sc_in<double> ca_in; /* It has 6 subunits of holoenzymes */ vector<camkii*> subunits; void init() { for( int i = 0; i < 6; i++) { stringstream name; name << "sub" << i; camkii* c = new camkii(name.str().c_str()); c->clock(clock); c->ca_conc_in(ca_in); subunits.push_back(c); } } void compute() { } SC_CTOR(camkii_ring) { init(); SC_METHOD(compute); sensitive << clock.pos(); } }; #endif /* end of include guard: CAMKII_H */ And here is my main.cc file. #include "camkii.h" #include <systemc.h> #include <iostream> using namespace std; int sc_main(int argc, char** argv) { sc_clock clock_("GlobalClock", 10, SC_MS, 0.5); sc_signal<double> ca_conc, i1p_conc; sc_signal<double> camkii_out; /* connect the camkii ring to ports */ camkii_ring camkii_ring("cakii_ring"); camkii_ring.clock(clock_); camkii_ring.ca_in(ca_conc); cout << "Starting ..." << endl; sc_start(100, SC_MS); return 1; } It compiles fine but when I run it Error: (E112) get interface failed: port is not bound: port 'cakii_ring.sub0.port_1' (sc_in) In file: sc_port.cpp:230

Hi all, I am creating some sc_signal<vector<T> > ports with a user defined T. I have already found a proper link for the same (answer provided by AR/Ravi, inheriting from STL vector). http://www.accellera...g=msg00004.html But now my question is, I am defining other ports where T will be sc_bv, double etc. So shall I write above code for each of the variable type or is it ok with all? (I am particularly worried about << and ==). Thank you. P.S. Will next IEEE1666 talk about sc_vector? Will some provision for above scenario provided in later versions?

Hi all, I have been trying to do something that I'm not sure it's possible. I have some TDF modules that are connected to each other by sca_in and sca_out ports. All of this modules will have at least one of each in/out ports. My idea was that maybe some of them will have some extra in/out ports. For example, if I want two TDFs outputs to go to one TDF input, it is not possible using just one port. Instead, those TDF modules would have a vector of sca_in's so, if I need an extra port, this will be initialized and bound to a signal. All this is already done and compiling. My problem is that when I initialize and bind that new port, it is not specifically assigned to a TDF so I get this error: "Error: (E100) port specified outside of module: port 'sca_tdf_in_0' (sc_port_base)". I understand the reason of this error, but I would like to know if it is possible to assign this port to its TDF. Here I will show my code, maybe it's helpful. class 'gen' is a generator of doubles. It sends an increasing double through its 'out' port. class 'pass' is just getting whatever comes from its 'in' port and sending it out through its 'out' port. class 'waste' is where the 'magic' may be. Receives whatever which is coming from 'pass'. main.cpp: #include <systemc-ams> #include "gen.h" #include "waste.h" #include "pass.h" int sc_main(int argc, char *argv[]) { gen g("g"); pass p("p"); pass p2("p2"); waste w("w"); sca_tdf::sca_signal<double> sig("sig"); sca_tdf::sca_signal<double> sig2("sig2"); sca_tdf::sca_signal<double> sig3("sig3"); g.out(sig); p.in(sig); // Both 'p' and 'p2' receive from the same signal 'sig'. p2.in(sig); // This works perfectly. p.out(sig2); // The out port of both are bound to different signals. p2.out(sig3); // Otherwise, I would get an error. w.in(sig2); // This is a normal binding (to 'p' and 'sig') that works just fine. w.bind(sig3); // Here's where I want to implement my idea. Look at 'waste.h' sc_core::sc_start(500.0, sc_core::SC_MS); sc_core::sc_stop(); return 0; }; waste.h: #ifndef WASTE_H #define WASTE_H #include <systemc-ams> #include <vector> SCA_TDF_MODULE(waste) { sca_tdf::sca_in<double> in; // Main 'in' port std::vector<sca_tdf::sca_in<double>*> secondary_ins; // Vector of extra 'in' ports std::vector<sca_tdf::sca_in<double>*>::iterator it; // Iterator int ins; // Number of extra 'in' ports SCA_CTOR(waste) { it = secondary_ins.begin(); ins = 0; } // This initializes the extra 'in' port and adds it to the vector // Here should go the 'assignation' if it is possible. void new_in() { sca_tdf::sca_in<double> *sec_in = new sca_tdf::sca_in<double>(); secondary_ins.insert(it, sec_in); ins++; } // This method is called in 'main.cpp' and it might assign // the new 'in' port to the given signal void bind(sca_tdf::sca_signal<double> &s) { new_in(); secondary_ins.at(secondary_ins.size()-1)->bind(s); } void processing() { double d = in.read(); std::cout << name() << " - main_in : " << d << std::endl; for(int i=0; i<secondary_ins.size(); i++) { double d2 = secondary_ins.at(i)->read(); std::cout << name() << " - sec_in(" << i << "): " << d2 << std::endl; } } }; #endif So basically that's it. Any ideas? Is it even possible? Thanks a lot
