ARM Inc. has announced two additional ARM11 family microprocessors, the ARM1176JZ-S core and the ARM1176JZF-S core that power a new version of the ARM11 core family-based PrimeXsys Platform.

The CPUs and platform are the first products to implement the company's TrustZone technology for enhanced security in open OS applications for portable and consumer devices, and are the first to integrate support for Intelligent Energy Manager technology which reduces processor energy usage by up to 75 percent.

The cores are based on the ARMv6 instruction set architecture and are targeted at service providers and operators that need to deliver products that support e-commerce and secure download of content through these next-generation of consumer devices. They include the AMBA 3.0 AXI System Bus Interface for higher memory bandwidth, simplified interconnect design and reduced time-to-market. Both cores also integrate Jazelle technology for efficient embedded Java execution, and include the ARM-Synopsys RTL to GDSII Reference Methodology within the deliverables.

Both cores are synthesizable and are expected to achieve 333MHz to 550MHz worst-case performance on a range of 0.13?m processes.
