Ticket Name: TDA2: TIDL library from vison SDK profiling cycles doesn't match with the prescribed cycles in the data sheet

Query Text:
Part Number: TDA2 I'm using TDA2X vision high board. I built the test application provided along with the TI deep learning library TIDL for EVE and loaded it on the EVE core from Debugger. The profiling results i got was: TEST_REPORT_INIT_PROFILE_DATA : TSC cycles = 1045023112, SCTM VCOP BUSY cycles = 0, SCTM VCOP Overhead = 0 TSC cycles are 1045023112 which is way higher than the promised cycles in the datasheet. What am I doing wrong. Please guide.

Hi Srinidhi, The number that you are observing the initialization cycles (it is one-time cycle, not the process cycle). The test execution is not complete. At end of execution below print is expected from TIDL test bench. below highlited is the cyclee required for one inference process TEST_REPORT_INIT_PROFILE_DATA : TSC cycles = 1090612854, SCTM VCOP BUSY cycles = 0, SCTM VCOP Overhead = 0 I/O Bytes : 183972592 ( 12396776 + 171575816 ) : 0 ( 0 + 0 ) Processing Frame Number : 0 TEST_REPORT_PROCESS_PROFILE_DATA : TSC cycles = 159966840, SCTM VCOP BUSY cycles = 115715684, SCTM VCOP Overhead = 0 I/O Bytes : 93366432 ( 61884464 + 31481968 ) : 197540112 ( 170210288 + 27329824 ) End of config list found !

Hi kumar, Yes this is in line with the numbers with the datasheet. But in "Embedded low-power deep learning with TIDL" document it says: It says at 0.700giga cycles(700 mega cycles) time was 194.44 ms. How to achieve this performance. Was this on EVE core? On vision High board i consider EVE at 535Mhz. What was the clock speed at which this was achieved? Thanks

The original question was for datasheet numbers in the TIDL SW release package. Regarding the new question abou the above table, this is for 4xEVEs running at 900Mhz. The model used for the abiove table is diffrenet from the one available in the TIDL SW. The above mentioned sparse model takes 188 mega cycles for one frame inference (Againt the 159 Mega cycles for the one in TIDL SW release opackage). The dense model number 700 mega cycles is for reference. I hope this clarifies your new question. Regards, Kumar.D

Hi Kumar, When will be the Single-shot detector based libraries out? Any date that we can expect of? Thanks
