Custom Processor CusP

[Altera_Forum]

Where is documentation to the sources file of cusp (cusp-engine-tests.jar\src\... ).

[Altera_Forum]

i don't think its public, what are you trying to do?

[Altera_Forum]

It's not documented for a reason..... hint you don't want to be poking around in there.

[Altera_Forum]

Because CusP is a better tool than SoPC and Qsys.

[Altera_Forum]

how did you arrive at that conclusion? if you look around the forum you'll find that cusp isn't supported and that Altera is porting cusp IP to HDL

[Altera_Forum]

CusP and SOPC Builder/Qsys have different purposes so it's a bit odd to even compare them. CusP is only on the ACDS for legacy reasons, it is not being maintained so I wouldn't recommend using it.

[Altera_Forum]

But Quartus recognizes CusP component and compiles.

[Altera_Forum]

CusP component is working, I tested on DE0 Nano. 

example: cusp_test4.c  # include <alt_cusp.h> SC_MODULE(cusp_test4) {  ALT_GPO<sc_bv<8>> led;    void behaviour()  {  int state = 0;   while(1)  {  for (state = 0; state <= 0xfff; state++) {   if (state == 0x1fff)  {  led.write(1);  }  else if (state == 0x3ff)  {  led.write(2);  }  else if (state == 0x5ff)  {  led.write(4);  }  else if (state == 0x7ff)  {  led.write(8);  }  else if (state == 0x9ff)  {  led.write(16);  }  else if (state == 0xbff)  {  led.write(32);  }  else if (state == 0xdff)  {  led.write(64);  }  else if (state == 0xfff)  {  led.write(128);  }  }  }  }    SC_CTOR(cusp_test4)  {  SC_THREAD(behaviour);  }; };

Use at your own risk then (no support, documentation, etc..) It's typically not a good idea to rely on unsupported features especially when the vendor is moving away from those same features.

[Altera_Forum]

Documentation is not needed, I compiled a new "CusP (no_lic)", everything is in the "cusp-engine-tests.jar". Altera make the mistake of not doing support for "CusP".

[Altera_Forum]

Full circle to my first post, there is a reason why it's not documented or supported.... It was experimental and wasn't persuded any further. I wouldn't recommend using for production since who knows how long it'll work for (or if it will even remain in the tools).

[Altera_Forum]

I have a question, also for Altera, if there is no documentation and support it would be possible to share this on open-source license.

[Altera_Forum]

Since CusP isn't open source licensed I wouldn't attempt to do so. The HDL output from the tool you can make available.

[Altera_Forum]

Not what I meant. 

"Altera" there is no documentation and support for users. Does the "Altera" may provide the source code and documentation on the open-source license.

[Altera_Forum]

Since it was internally developed and never offered as a product the answer is no it cannot be offered under an open source license. You can try asking your FAE to see if they can make a request but I don't think you'll get a different answer.

[Altera_Forum]

if you're interested in open source, have you thought about trying or contributing to myHDL?

[Altera_Forum]

Please give me an email to FAE. 

To write simple programs, only need to me a verilog or vhdl. To write something more difficult, is needed a "hardware accelerator", "myHDL"is not suitable. I am currently writing a "Cellular Neural Networks (CNN)" program in the "CusP".

[Altera_Forum]

It turns out that, I do not have adequate competence to ask such questions on "CusP" and "eperl.exe" error (the human factor). This means that I know how to decode the files "*.epl (generate_rtl.epl) ". Maybe if I wrote on the forum how to do it, someone from Altera to finally talk to me.

[Altera_Forum]

Hi.  

I am new user on this forum, and not very spike to english, I am polish. To "goeth": I would like to know about the cusp.

[Altera_Forum]

Wi&#281;c pogadamy po polsku, bo w sumie ja te&#380; dobrze nie znam angielskiego. 

Pewnie chcia&#322;by&#347; si&#281; czego&#347; dowiedzie&#263; na temat programu "cusp" to skrót od Custom Processor czyli ten program z komponentu opisanego w j&#281;zyku SystemC generuje ten komponent w j&#281;zykach vhdl lub verilog w archtekturze tak zwanej ASIP (Application Specific Instruction set Processor) w pisz w google to co w nawiasie to co&#347; znajdziesz na temat tej architektury. A konkretnie dokumentacji odno&#347;nie tego programu to nie znalaz&#322;em ale znalaz&#322;em dwie publikacje s&#261; w za&#322;&#261;czniku, w j&#281;zyku angielskim. Je&#347;li wolno spyta&#263; to co konkretnie chcesz napisa&#263;.

[Altera_Forum]

Kudos for reverse engineering CusP. Yeah you're not going to get anything from Altera on this. But Mentor has a C->Hardware tool that Altera considered using to replace CuSP (Catapult-C I think). Definitely not free though.
