Forum Post: EZSDK memory map question / IPC_SR_HOST_DSP / IPC_SR_MC_HDVICP2_HDVPSS

Hi,

We use EZSDK 5_05_02_00 and dm8148 based custom board with 512MB DDR.  We are developing an application which needs H264 encoder and custom DSP code.

We basically followed http://processors.wiki.ti.com/index.php/EZSDK_Memory_Map / MEMORY MAP TABLE FOR DEFAULT 512MB SYSTEM to setup the memory map.

The questions are:

Q1:  IPC_SR_HOST_DSP -- is this a shared region used for syslink for ARM / DSP communication?

Q2:  So we need to specify the address 0x99400000 in dsp.cfg (and platform)?   Do we need to define this memory area in other places (such as memseqdef_default.c)?

Q3:  IPC_SR_HOST_DSP and IPC_SR_MC_HDVICP2_HDVPSS must use different memory regions, correct?

Thanks,
