New ARM9E Family Core Provides Unrivalled Low-Power Performance

The ARM968E-S core has a low latency AMBA™ AHB-lite bus interface, and separate core and DMA clocking for low power idle mode operation. The ARM968E-S core integrates these benefits in a size that is 20 percent smaller than the ARM966E-S™ core and gives power savings of at least 10 percent.

The ARM968E-S core introduces a dedicated Direct Memory Access (DMA) port with tightly coupled memories (TCM) support. These enhanced benefits improve the efficiency of packet processing and data throughput, increasing the communications capacity of devices based on the new core. The DMA capability is particularly suited to communications devices such as 802.11 clients, Firewire or SCSI interfaces, but also applies to areas like audio where streams of data need to be processed.
