H.264 and H.265 standards encoding/decoding.

Up to eight simultaneous streams.

8K x 4K at a reduced frame rate.

Progressive video only (no interlace support).

I, IP, and IPB encoding/decoding.

8-bit and 10-bit color depth, YCbCr 4:2:2 and 4:2:0 video formats, and up to a 4K x 2K@60/8K x 4K@15 Hz rate.

Low-latency mode.

Low software overhead for slice-level management and multi-stream switching.

Functions to queue tasks to eliminate dependency on CPU interrupt response time.

Power management.

°Clock and Power Island Controls.

°Built-in power sequencing state machine or interface to an external one.

Performance monitoring.

°Task execution time.

°Bandwidth and AXI transaction count.

°Min, max, and average AXI transaction latency.

The VCU contains encoder and decoder interfaces. The VCU also contains additional functions that facilitate the interface between the VCU and the PL.

VCU operation requires a small amount of processor activity. Interrupt response time must not be critical. The encoder is controlled by the CPU through a task list prepared in advance, and the CPU response time is not in the execution critical path. The VCU has no audio support. Audio encoding and decoding is supported on the PS application processors.
