Inversion Mode) and/or the microcode level being used. The typical time ranges for latency are as follows:
Latency Notes
The above latency time ranges include internal encoder latency only. Compressed data output buffering and
other system latency is not included.
The time units associated with 1 frame are dependent on the specified frame rate (e.g. for a 1 frame latency with
a frame rate of 30 per second, the latency is 33 milliseconds).
The above latency time ranges do not guarantee a fixed timing relationship between the pixel interface VR signal
and HENC_INTRPT. System designers must not rely on such a relationship when using the encoder in a system
since it can change based on encoding parameters and/or microcode level.
Encoder Memory Requirement
Two external memories are needed to support the encoder. These include frame memory and compressed data
output memory components. The required size, type and speed of each external memory is defined in the following
