The IBM PowerPC
processors will be distributed as fully soft register transfer level (RTL)
cores which can be easily implemented in any foundry process and configured to
product design requirements including low power, high performance, or small
silicon area. These design tools can help designers to
address the full range of design issues including power reduction, signal
integrity, design for manufacturing (DFM) and verification. The DesignWare Library
Portfolio includes foundry libraries, verification IP, AMBA(TM) bus IP and
peripherals , memories, building block IP and microcontrollers. More information is available at:
