Unable to change cache size in codec engine.
Hello ,
I am trying to build an application to encode video in mpeg4 format
and also integrate the scale example from the codec engine in the
encode combo server. During the integration fro performance reasons I
want to increase the L2 cache size from 64k to 128k. My processor is
tms320dm6446.
On building the codec_server I get the error:
Error: Can't set cache to size: 128k
Following is the encode.tcf file:
/*
* Setup platform-specific memory map, CLK rate, etc.
*/

Re: Unable to change cache size in codec engine.
Refer to tms320dm6446.pdf /p14 (datasheet of TMS320DM6446) DSP has only
64KB
The DSP Subsystem includes the following features:
· C64x+ DSP CPU
· 32KB L1 Program (L1P)/Cache (up to 32KB)
· 80KB L1 Data (L1D)/Cache (up to 32KB)
· 64KB Unified Mapped RAM/Cache (L2)
· Little endian

Subject: Re: Unable to change cache size in codec engine.
I am referring doc spru871j.pdf. In the section Level 2 memory and
cache it is mentioned that the L2 cache size can be configured for
32KB, 64KB, 128KB and 256KB. I presume the L2_CACHE is same as this.
If there is any other doc whcih specifies that the cache size
configured is limited to 64KB please refer the same to me.
