IVA2.2 Subsystem Overview
The device includes the high-performance Texas Instruments image video and audio accelerator (IVA2.2),
based on the TMS32 VLIW digital signal processor (DSP) core.
The internal architecture is an assembly of the following components:
•
High-performance TI DSP (TMS32) integrated in a megamodule, including local L1/L2
cache and memory controllers
•
L1 RAM and L2 RAM and ROM
•
Video hardware accelerator module, including local sequencer
•
Dedicated enhanced data memory access (EDMA) engine to download/upload data from/to memories
and peripherals external to the subchip
•
Dedicated memory management unit (MMU) for accessing level 3 (L3) interconnect address space
•
Local interconnect network
•
Dedicated modules SYSC and WUGEN in charge of power management, clock generation, and
connection to the power, reset, and clock manager (PRCM) module
shows the IVA2.2 subsystem top-level architecture.
