Brief Description

VPU

Video Processing Multimedia

Unit

Peripherals

A high-performing video processing unit (VPU) version 3, which covers

many SD-level video decoders and SD-level encoders as a multi-standard

video codec engine as well as several important video processing such as

rotation and mirroring.

VPU Features:

• MPEG-2 decode, Mail-High profile, up to 1080i/p resolution, 40 Mbps bit

rate

• MPEG4/XviD decode, SP/ASP profile, up to 1080 i/p resolution, 40 Mbps

bit rate

• H.263 decode, P0/P3 profile, up to 16CIF resolution, 20 Mbps bit rate

• Sorenson H.263 decode, 4CIF resolution, 8 Mbps bit rate

• H.264 decode, BP/MP/HP profile, up to 1080 i/p resolution, 40 Mbps bit

rate

• VC1 decode, SP/MP/AP profile, up to 1080 i/p resolution, 40 Mbps bit

rate

• RV10 decode, 8/9/2010 profile, up to 1080 i/p resolution, 40 Mbps bit rate

• DivX decode, 3/4/5/6 profile, up to 1080 i/p resolution, 40 Mbps bit rate

• MJPEG decode, Baseline profile, up to 8192 x 8192 resolution,

40 Mpixel/s bit rate for 4:4:4 format

80 Mpixel/s bit rate for 4:2:2 format

WDOG-1 Watch Dog

Timer

Peripherals

The watch dog timer supports two comparison points during each counting

period. Each of the comparison points is configurable to evoke an interrupt

to the ARM core, and a second point evokes an external event on the

WDOG line.

WDOG-2 Watch Dog

(TZ)

(TrustZone)

Timer

Peripherals

The TrustZone watchdog (TZ WDOG) timer module protects against

TrustZone starvation by providing a method of escaping normal mode and

forcing a switch to the TZ mode. TZ starvation is a situation where the

normal OS prevents switching to the TZ mode. This situation should be

avoided, as it can compromise the system’s security. Once the TZ WDOG

module is activated, it must be serviced by TZ software on a periodic basis.

If servicing does not take place, the timer times out. Upon a time-out, the

TZ WDOG asserts a TZ mapped interrupt that forces switching to the TZ

mode. If it is still not served, the TZ WDOG asserts a security violation

signal to the CSU. The TZ WDOG module cannot be programmed or

deactivated by a normal mode SW.
