Applied Micro X-Gene 64-Bit ARMv8 Server-on-Chip Presentation

Applied Micro Showcases World’s First 64-bit ARMv8 Core at ARM Techcon 2011, Santa Clara California. The day ARM announced the first 64-bit ARMv8 instruction set architecture, AppliedMicro unveiled the launch of the industry’s first 64-bit ARM “Server-on-a-Chip” solution. Most of the presentation is used to explain the competitive advantage this platform would bring including TCO reduced by 30%. There is also an (underwhelming) demonstration of X-Gene based on Xilinx Virtex-6 FPGA running Server SoC consisting of ARM-64 CPU complex, coherent CPU fabric, high performance I/O network, memory subsystem along with fully functional SoC subsystem. The FPGA platform and tools will be available for customer evaluation by the first half of 2012. Redhat will be in charge of implementing ARMv8 support in Linux and this will be part of Fedora for ARM in the future. The platform will run LAMP: Linux, Apache, MySQL and Perl/PHP/Python. The silicon will be available in H2 2012 and they expect most of the key software […]

Bootloader to OS with Unified Extensible Firmware Interface (UEFI)

Unified Extensible Firmware Interface (UEFI) is a specification detailing an interface that helps hand off control of the system for the pre-boot environment (i.e.: after the system is powered on, but before the operating system starts) to an operating system, such as Windows or Linux. UEFI aims to provides a clean interface between operating systems and platform firmware at boot time, and supports an architecture-independent mechanism for initializing add-in cards. UEFI will overtime replace vendor-specific BIOS. It also allows for fast boot and support for large hard drives (> 2.2 TB). There are several documents fully defining the UEFI Specification, API and testing requirements: The UEFI Specification (version 2.3.1) describes an interface between the operating system (OS) and the platform firmware. It describes the requirements for the following components, services and protocols: Boot Manager Protocols – Compression Algorithm Specification EFI System Table Protocols – ACPI Protocols GUID Partition Table (GPT) Disk Layout EFI Byte Code Virtual Machine Services — Boot […]
