MPC184VMB

P1-P3P4-P6P7-P9P10-P12
This technical summary provides an overview of the MPC184 security processor, including a
brief development history, target applications, key features, typical system architecture, device
architectural overview, and a performance summary.
1 Development History
The MPC184 belongs to the Smart Networks platform’s S1 family of security processors
developed for the commercial networking market. This product family is derived from
security technologies Motorola has developed over the last 30 years, primarily for government
applications. The fifth-generation execution units (EU) have been proven in Motorola
semi-custom ICs and in other members of the S1 family, including the MPC180, MPC190,
and MPC185.
2 Typical Applications
The MPC184 is suited for applications such as the following:
• SOHO VPN routers
• Customer Premise Equipment
• Wireless Access Points
• eCommerce servers
• Dedicated Encryption Modules
3 Features
The MPC184 is a flexible and powerful addition to any networking or computing system using
the Motorola PowerQUICCline of integrated communications processors, or any system
supporting 32-bit PCI. The MPC184 is designed to off load computationally intensive security
functions, such as key generation and exchange, authentication, and bulk encryption from the
host processor.
The MPC184 is optimized to process all the algorithms associated with IPSec, IKE,
WTLS/WAP, SSL/TLS, DOCSIS BPI+, 802.16, and 802.11(WEP). In addition, the Motorola
family of security co-processors are the only devices on the market capable of executing

MOTOROLA MPC184 Security Processor Technical Summary 3
Figure 4-1) or any system using PCI. The ability of the MPC184 to be a master on the 8xx bus allows the
co-processor to offload the data movement bottleneck normally associated with slave devices. The external
processor accesses the MPC184 through its device drivers using system memory for data storage. The
MPC184 resides in the memory map of the processor, therefore when an application requires cryptographic
functions, it simply creates descriptors for the MPC184 which define the cryptographic function to be
performed and the location of the data. The MPC184’s mastering capability permits the host processor to
set up a crypto-channel with a few short register writes, leaving the MPC184 to perform reads and writes
on system memory to complete the required task.
