GC7000 Nano Ultra

Graphic Processing

Unit

GPU-3D

Multimedia

i.MX 7ULP integrates the Vivante

GC7000 Nano Ultra Graphic Processing

Unit (GPU-3D). supporting OpenGL

ES2.0/1.1, Desktop OpenGL 2.1,

OpenVG1.1, and GLSL shading

language support.

Hardware Semaphore SEMA42_0 and

SEMA42_1

Multicore Peripherals

and Resource Domain

Control submodules

AD, RT

The Hardware Semaphore (SEMA42)

module provides the hardware support

needed in multicore systems for

implementing semaphores and provide a

simple mechanism to achieve "lock/

unlock" operations via a single write

access. SEMA42_0 is in the real-time

domain. SEMA42_1 is in the application

domain.

Input/Output

Multiplexing

Controller

IOMUXC0-1 &

IOMUXC_DDR

System Control

AD, RT

The Input/Output Multiplexing Controller

(IOMUXC) enables the chip to share one

pad for multiple signals from different

peripheral interfaces. This pad sharing

mechanism is done by multiplexing the

pad's input and output signals. The

IOMUXC also controls the pads setting

parameters and digital filter functions of

the pad. In addition, the IOMUXC

controls input multiplexing logic for input

signals multiplexed at multiple locations.

IOMUXC0 is in the real-time domain.

IOMUXC1 and IOMUXC_DDR are in the

application domain.

Internal Reference

Clock 1kHz

IRC1K

Clock Sources and

Control

SYS

The Internal Reference Clock 1kHz

(IRC1K) module is an internal oscillator

that can generate a reference clock of

1kHz. The IRC1K clock is enabled in all

modes of operation, including all low

power modes.

Joint Test Action

Group Controller

JTAGC

Debug

Joint Test Action Group Controller

(JTAGC) provides the means to test chip

functionality and connectivity while

remaining transparent to system logic

when not in test mode. Testing is

performed via a boundary scan

technique, as defined in the IEEE

1149.1-2001 standard.

LCD Interface

Controller

LCDIF

Multimedia

The LCDIF is a general purpose display

controller used to drive a wide range of

display devices varying in size and

capabilities. The LCDIF is used as a
