  1. For the smart meter development, the hardware consists of MCU, DSP,and an external memory. We programmed after finished the hardware. Although MCU provides some functions like DSP and embedded memory on it. We still need external chips to meet SPEC's requirement due to the signal accuracy and the memory capacity. Once, the performance can't satisfy the SPEC and we had to do everything again. With TLM, we can get modules from IP providers and have abstraction modeling for the specification. Finally we can make a SoC (System on Chip) according to SPEC. In other words, we won't have useless c
  2. Most of materials mentioned TLM, however, there are many discussions on TLM. For example, specification model, component-assembly model, bus-arbitration model, Bus-functional model, Cycle-accurate computation model and implementation model introduced by Lukai Cai and Daniel Gajski,"Transaction Level Modeling: An Overview". It will be great to understand them for choosing a right model on your simulation. In fact, I participated a project for developing the smart meter specified by IEC 62056 few years ago but our work was not successful because of the wrong modeling methodology(software and ha
  3. Remember to build your own systemc.lib .
  4. Dear Alan : David's "SystemC from the Ground Up" is a lovely book. It reminds me someone.
  5. Thanks for your suggestions. I will study both. regards David
  6. I would like to point out what differences between them. 1. A SystemC Primer focus on digital hardware. However, some descriptions are outdated. Users may refer SystemC 2.0.1 Language Reference Manual Revision 1.0 to modify them. 2. SystemC 2.0.1 Language Reference Manual Revision 1.0 only shows you the definition of SystemC. 3. SystemC Version 2.0 User’s Guide will explain how to build the communication protocol on SystemC. Unfortunately, the codes of examples in those documents are outdated or not complete. If somebody mix three of them and fix the mentioned problems, th
  7. Personally, I recommend following documents for beginners. You can find them with google. 1. A SystemC Primer J. BHASKER 2. SystemC 2.0.1 Language Reference Manual Revision 1.0 3. SystemC Version 2.0 User’s Guide
  8. Please get "systemc 2.0.1 language reference manual" online with google. In chapter 7 Modules, it will show you how to define a sc_module .
  9. Hi : Sirs I found a technical paper introducing Named pipes to share data bidirectionally synchronously or asynchronously for GUI front-end on a command-line app. Dr. Dobb's Web site : Using Named Pipes to Connect a GUI to a Console App in Windows
  10. Hi : ElliottCB : You can refer and modify the following example as your template, actually it was modified by using SystemC example (pipe project as i remember). Due to the version of SystemC, some descriptions indicated in old documents can not work properly at this moment. That will be a major problem for you as a beginner. It works after referring many documents and examples about SystemC. Good Luck to make it happen #define DISPLAY_H // display.h #include "systemc.h" class display : public sc_module { public: sc_in<bool> inPort0; sc_in<bool> inPort1;
  11. Hi : I would like to provide my experience of programming on both Qt and Visual C++ platforms. Yes, there is a limitation for the compiler specially when you program with a thread(process). It will shunt down if you generate a large file up to around 500M byte with a thread under Qt platform . Although I modified codes by using the dynamic allocation, it still shunt down. Finally, i just re-wrote it under console mode(DOS mode). Recently, i try the new version of visual C++, it can generate a file up to 7G bytes with a thread. By the way, Bjarne Stroustrup(creator of C++) has an idea fo
  12. I heard there is a ADC for impedance control on DRAM output circuit. Hope the diagram can help... Impedance calibrations using external resistor
  13. Actually, from the view of the hardware, we always read/write n bits data with an address. I think your work is similar to the attached file. You can define your hardware architecture according to page 25 of the attached file. http://cseweb.ucsd.edu/~swanson/papers/HotChips2010GreenDroid.pdf
  14. Entry point is the first problem but I think it is possible to be solved .Furthermore, if you want to create separate processes, you still consider windows programming (it provides a real multitask environment). I learn from SystemC. It looks like having it's own scheduler for multitask processing(similar to MicroC/OS). As i knew, there was a thought from OSCI for replacing such scheduler by using OS threads.
