Ticket Name: TDA2P-ACD: Several questions for using TDA2 with radar

Query Text:
Part Number: TDA2P-ACD Other Parts Discussed in Thread: TDA2, AWR1243, TDA2PXEVM Hello team, My customer has the plans to use TDA2 to use it with AWR1243 and perform first order FFT and second order FFT using TDA2 devices and to perform it on the 2.5MB L3 RAM On-chip (without DDR2/3). 1. could you please advise if our device can use the C66x DSP without external DDR2? 2. there is a need to have at least 2.5GB throughput of output data from the device, what is the best I/F for doing that (I think the PCIe II could do the trick)? 3. what is the PN chipset that comes with TDA2PXEVM (the customer is looking for TDA2PHF-ACD chipset EVM)? 4. Could you please advise if the upcoming TDA4 comes with higher memory (on-chip) in the L3 RAM than the TDA2 (2.5MB)? Thanks in advance Shai

Responses:
Hi Shai, There are couple of things to look at: What is the Radar cube you are looking at? We could have C66x code running from OCMC RAM along with rest of the radar cube, but a memory partition needs to be done on what is the code/data section requirements for C66x and then plan for a DDR less system. Are there other cores you are looking at for running code out of OCMC? PCIe would do the trick if the requirement is 2.5 Gbits per second. For the PCIe if you would like to have enumeration features, the linux PCIe drivers are more mature than bare metal PDK drivers. With Linux in the picture, it would be a challenge to fit everything in a DDR less system. The EVM comes with a pre-production part DRA77xP/DRA76xP/TDA2Px (Superset SoC) . For TDA4x specific questions please contact your TI representative. Thanks and Regards, Piyali
