Note:

1.

All these memory requirements are for DVCPro50 decoder library only. They do not include any memory requirements

from test application side. Stack, heap and code requirements for test-application are extra.

2.

All memory requirements are expressed in kilobytes (1K bytes = 1024 bytes).

3.

The memory requirements given in Table 3 are calculated for D1 PAL resolution.

4.

Typical input and output buffers for D1 PAL resolutions are as follows.

Input Buffer: 282KB

Output Buffer:810KB

5.

One output buffer is sufficient as a part of DPB i.e only Intra frames are allowed in the standard.

Note:

1.

Decoder stack is mapped to Local L2 memory and not included in the above table.

2.

Constant and Persistent memory can be corrupted by application provided application uses algorithm activate and

deactivate APIs before using process and control APIs

All memory requirements are expressed in kilobytes (1K bytes = 1024 bytes).
