The /spl mu/PP ASIC: design, methodologies and tools for a pay phone system-on-a-chip based on an ARM core and design reuse

This paper describes the /spl mu/PP (Microcontroller for Pay Phones) ASIC, a system-on-a-chip solution based on the present Spanish pay phone system. The design integrates an ARM embedded microprocessor, several third party blocks and new custom modules developed in house, using ARM's Advanced Microprocessors Bus Architecture (AMBA). The system has been designed for low power consumption and management. Design reuse, aided by the use of new management tools, and co-design, allowed an important reduction in global design time.
