Auto vectorization is being increasingly common but it’s only as good as the native instruction support so we believe auto vectorization with our SIMD will be quite effective.” The P5600 incorporates Enhanced Virtual Address (EVA) and Extended Physical Address (XPA) features that enable scalability to future generations of products. EVA enhances the effective use of the virtual memory space in the P5600, allowing both user and kernel space to access more than 3GB of space each without the need for HIGHMEM support in Linux. XPA extends the physical addressing capabilities of the P5600 up to 1 Terabyte. In combination with hardware virtualization, EVA and XPA extend the usability of the P5600 well beyond other 32-bit CPUs. The devices have security applications in mind, with hardware virtualization that separates out the user and root capabilities and allows existing hypervisors to be ported to the new core without requiring modification. “We took a CPU view of hardware virtualization, we have virtualized both the I/O processes and interrupts at the cluster level so I/O is transactional within each virtual domain.” Imagination plans to use virtualization as the foundation for a growing number of applications demanding robustness, support for multiple security contexts and more. Starting with the P5600, MIPS Series5 cores embrace hardware virtualization from the entry level to the high end, with simple, flexible and complete virtualization across the MIPS Series5 range. The silicon footprint for the P5600 is up to 30% smaller than comparable CPU cores with performance exceeding 5 Core- Mark/MHz with 3.5 DMIPS/MHz. At a system level the core shows 1.2x – 2x performance gains on the previous Aptiv family on a wide variety of system-oriented benchmarks, including SPECint2000, Linpack, and Javascript/Browser tests, and 2x – 3x higher data movement on widely-used routines such as MemCopy libraries* There is support for up to six cores per cluster with highperformance cache coherency to support a 4.1 or 4.2 scheme combining high frequency, high leakage versions of the core with lower leakage, lower frequency variants Imagination aims to provide binary compatibility across the range of Series5 Warrior CPUs, from entry-level/microcontroller CPUs up to high-end performance-driven networking systems. MIPS Series5 cores share a common datapath for execution of all 32-bit and 64-bit code, ensuring that 32-bit binaries for any ‘Warrior’ CPU will run without change on any 64-bit ‘Warrior’ CPU. The MIPS P5600 will be available for licensing this quarter while cores based on the v8-R architecture will be announced next year, with silicon from partners in the second half of 2015. The first devices will emerge for the industrial market even though the main focus is automotive, says York, and the same cores will be used for both. “The main competition is proprietary architectures,” he said. “The people we are talking to are using Freescale PowerPC, Renesas SH, Infineon Tricore or Renesas V850.” The first device XMOS XA device is the XA-U8-1024, features eight 32bit processors (seven xCORE logical cores plus an ARM Cortex-M3 processor), 192KB SRAM, and 1024KB of Flash and will sell for around $15, says Toon. The device includes a low energy USB interface, ultra low-energy peripherals and analog functions including ADC, DAC, op-amps and capacitive sensing comparators. Future family members will include 6-core and 8-core products with Flash sizes ranging from 512KB to 1024KB, and device variants with or without the low-energy USB 2.0 interface.
