In the past, designers were faced with the task of interfacing a microprocessor to several peripherals and their necessary glue logic, which was expensive in terms of board space and power requirements, and upgrades were difficult to perform. Another challenge was implementing the many protocols and interfaces between the different network segments, while achieving the required system bandwidth. On the other side of the dual port RAM is a microprocessor for data link layer and maintenance processing, as well as the SIU, which consists of a versatile programmable memory controller, reset circuitry, PLL, and timers. Select the specific family member which satisfies your data rate requirements and enjoy the benefits of a flexible, cost-effective design. In ATM mode, the local bus is used to store connection tables for active ATM connections.
Additional ports remain available for system management functions.
Network security protocols involve processing sophisticated, compute-intensive algorithms, which can reduce system performance by monopolizing the host processor. The MPC180 Security Processor is easily integrated into systems already using Motorola's processors, and utilizes existing system memory, resulting in significant savings of both board space and system cost.
