Mbits SDRAM.
External memory is SDRAM. It is possible to use the following.
The
This system uses only CAS latency = 3, burst length = 4.
When encode using time base corrector and/or displays local decoding picture, it needs equal to or more than 64
When PAL encoding, it needs equal to or more than 64 Mbit SDRAM.
When transcoding, it needs equal to or more than 64 Mbit SDRAM.
