= Design Overview =
The heart of Axel module is composed by the following components:
* Freescale i.MX6 Solo / Dual / Quad core SoC application processor
* Power supply unit
* DDR memory banks
* NOR and NAND flash banks
* 3x 140 pin connectors with interfaces signals
This chapter shortly describes the main Axel Ultra components.
== Processor Info ==
The i.MX6 Solo/Dual/Quad processors feature Freescale’s advanced implementation of the ARM® Cortex®-A9 MPCore, which operates at speeds up to 1.2 GHz. They include 2D and 3D graphics processors, 1080p video processing, and integrated power management. As a result, the i.MX6 devices are able to serve a wide range of applications including:
* Automotive driver assistance, driver information, and infotainment
* Multimedia-centric smart mobile devices
* Instrument clusters, and portable medical devices.
* E-Readers, smartbooks, tablets
* Intelligent industrial motor control, industrial networking, and machine vision
* IP and Smart camera
* Human-machine interfaces
* Medical diagnostics and imaging
* Digital signage
* Video and night vision equipment
* Multimedia-focused products
* Entertainment and gaming appliances
The i.MX6 application processor is composed of the following major functional blocks:
* ARM Cortex-A9 MPCore 2x/4x CPU Processor, featuring:
** 1 Megabyte unified L2 cache shared by all CPU cores
** NEON MPE coprocessor
** General Interrupt Controller (GIC) with 128 interrupt support
** Snoop Control Unit (SCU)
** External memories interconnect
* Hardware accelerators, including:
** VPU -Video Processing Unit
** Two IPUv3H -Image Processing Unit (version 3H)
** 2D/3D/Vector graphics accelerators
* Connectivity peripherals, including
** PCIe
** SATA
** SD/SDIO/MMC
** Serial buses: USB, UART, I²C, SPI, ...
Axel Ultra can mount three versions of the i.MX6 processor. The following table shows a comparison between the processor models, highlighting the differences:

== RAM memory bank ==
DDR3 SDRAM memory bank is composed by 4x 16-bit width chips resulting in a 64-bit combined width bank. The following table reports the SDRAM specifications:
{| class="wikitable" |
|-
| '''CPU connection'''||Multi-mode DDR controller (MMDC)
|-
| '''Size min'''||512 MB
|-
| '''Size max'''||4 GB
|-
| '''Width'''||64 bit
|-
| '''Speed'''||533 MHz
|-
|}
== NOR flash bank ==
NOR flash is a Serial Peripheral Interface (SPI) device. This device is connected to the eCSPI channel 5 and by default it acts as boot memory. The following table reports the NOR flash specifications:
{| class="wikitable" |
|-
| '''CPU connection'''||eCSPI channel 5

| '''Size min'''||8 MB
|-
| '''Size max'''||64 MB
|-
| '''Chip select'''||ECSPI5_SS0
|-
| '''Bootable'''||Yes
|-
|}
== NAND flash bank ==
On board main storage memory is a 8-bit wide NAND flash connected to the CPU's Raw NAND flash controller. Optionally, it can act as boot peripheral. The following table reports the NAND flash specifications:
{| class="wikitable" |
|-
| '''CPU connection'''||Raw NAND flash controller

|}
== Memory map ==
For detailed information, please refer to chapter 2 “Memory Maps” of the i.MX Applications Processor Reference Manual.
== Power supply unit ==
Axel, as the other Ultra Line CPU modules, embeds all the elements required for powering the unit, therefore power sequencing is self-contained and simplified. Nevertheless, power must be provided from carrier board, and therefore users should be aware of the ranges power supply can assume as well as all other parameters.
== CPU module connectors ==
All interface signals that Axel Ultra provides are routed through three 140 pin 0.6mm pitch stacking connectors (named J1, J2 and J3). The dedicated carrier board must mount the mating connectors and connect the desired peripheral interfaces according to Axel Ultra pinout specifications.
