New Contributorwhere is ap_uint or ap_int c++ type defined
hello,
Recently I tried to review and understand HLS architecture in Quartus tools,
in hls/include/HLS/ac_int.h, there were many instances of ap_uint or ap_int
type referenced but I couldn't find any definition about them, would you please
help me to confirm that whether if this specific type was intrinsic to i++ (Intel
HLS compiler)? if not where can I find the proper definition of it? much appreciate for the guideance

LiyenHello,
To follow up my own question posted several days ago, I am trying to create a HLS design upon
Cyclone V soc (with dual arm cortex A9), it's clear that I can develop HLS IP components to optimize
system bottleneck, I would also like the entire design to be run on this soc so ability to communicate
between processor core(s) to HLS IP(s) is critical, would you anyone please guide me how to and/or
point me the appropriate online design documents? much appreciate

Hi Liyen,
The references for the ap_uint/ap_int in intel hls can be found in the document below:
As for the example design to create an IP when installed intel HLS, it is already provided as part of the installation, which can be found in the path below:
- <quartus_installdir>/hls/examples/<design_example_name>
Thanks.

Hello Aik,
Thanks for the pointers, I did mean the definitions of ap_uint and ap_int, instead ac_uinnt and ac_int,
which were apparently derived some sort from the former, anyway I supposed these most likely are
the intrinsic datatype specific to i++, in fact, I observed these arbitrary precision datatype from Xilinx
git repo one day, perhaps they are very close to what were utilized in Altera HLS. thank you very much
anyway, plus I do have another question about Quartus standard edition, which is the single seat pricing?
do you have any idea?
