3.2.3 General-Purpose Interfaces

There are 4 GPIO banks, each of which has 32 I/O pins, giving a total pin
number of 128 (4x32).

3.2.4 Programmable Real-Time Unit Subsystem

The PRUSS of AM3359 consists of 2 programmable real-time units; a 12KB
shared RAM with single-error detection (parity), tree 120B register bank
that can be accessed by each PRU, an interrupt controller module used to
process input events of the system, and the following peripherals:
 UART with data flow control and maximum rate of 12Mbps
 Two MII Ethernet interfaces with support for industrial Ethernet such
as EtherCAT™
 A MDIO interface
 An enhanced capture module (eCAP)
3.2.5 3D Graphics Engine
The POWERVR SGX graphics acceleration subsystem is used to improve 3D
image processing, as well as to provide regular display and gaming effects.
The subsystem features:
 Tile-Based Architecture Delivering Up to 20 MPloy/sec
 Universal Scalable Multi-Threaded Shader Engine Incorporating Pixel
and Vertex Shader Functionality
 Advanced Shader Feature Set in Excess of Microsoft VS3.0, PS3.0 and
OGL2.0
 Industry Standard API Support of Direct3D Mobile, OGL-ES 1.1 and
2.0, OpenVG 1.0, and OpenMax
