Home Entertainment Gateway MCF547x

ColdFire

Microprocessor Application

Overview

A home entertainment gateway is a communication and storage hub in the home that functions as a secure audio,

video, and file server; wireless router and firewall; and a personal video recorder.

Key Benefits

> Enables a wide range of

home entertainment gateway products that can be developed based on the same core design using the different PCI peripherals on the MCF547x devices

> Delivers high data throughput

for communications-intensive peripherals included in a gateway application provided by the device’s system architecture on the MCF547x

> Helps to ensure secure

transmission of data through the gateway with the hardware-accelerated encryption on the MCF547x devices

Design Challenges

The key requirements of a microprocessor for the home entertainment gateway application are connectivity and price/performance. Processors for this application require dual Fast Ethernet interfaces for routing; a USB 2.0 device controller; and a PCI bridge to interface to the IEEE 802.11a/ b/g radios, (serial) ATA storage controller, MPEG2/AC3 video/audio

SG2062-3

processor and optional IEEE 1394 controller. In addition, they require an I

C bus for controlling the video components and an infrared-capable serial port for IR remote control. The processor must have sufficient performance and memory bandwidth to handle simultaneous A/V recording and playback, routing, and file serving. A crypto engine is also required in order to accelerate encryption for the

wireless link and to encrypt files stored on the hard disk.

Because the home entertainment gateway application is an embedded, always-on device that requires a reliable RTOS or Linux® operating system, full memory management capability is an asset.

Freescale Semiconductor Solution

The MCF547x Family provides the essential connectivity requirements for a home entertainment gateway. It features a V4e ColdFire® core with large dual 32 KB caches that deliver 410 MIPS (Dhrystone 2.1) of performance at 266 MHz. The Memory Management Unit (MMU) allows a full protected-mode OS, such as standard Linux OS, to be used.

The 32-bit wide DDR SDRAM controller provides high-memory bandwidth for A/V, storage, and network data. The onchip 32 KB SRAM can be used to store critical routines and data, in addition to keys and initialization vectors for the onchip crypto engine.

The serial peripherals (dual Fast Ethernets, USB 2.0 device, I

C and four

programmable serial ports) are

supported by DMA channels to minimize CPU overhead. The integrated PCI bridge supports bus mastering for direct transfers to and from memory.

With the required key functionalities integrated into the MCF547x Family, a range of home entertainment gateway products can be developed based on the same core design, but with different PCI peripherals and software.
