Marvell shows off the new OLPC XO-4 powered by the Marvell PXA2128 dual-core 1.2Ghz, Marvell 8787, and uses Neonode IR touch screen technology to thus add touch functionality to the One Laptop Per Child XO-4 laptop. Performance is thus increased and battery life further improved by using this latest 40nm process node Marvell ARM Processor in the upgrade.
The XO 4.0 is powered by the Marvell ARMADA PXA2128. Optimized by ARM v7 high-performance mobile processors with Hybrid-SMP technology at up to 1.2GHz, the PXA2128 reduces power consumption by roughly half and enables an extended battery life thanks to a low-power mobile (LPM) processor.
Features of the Marvell ARMADA PXA2128 include:
Marvell optimized ARM®v7 dual High-Performance Mobile (HPM) processors with Hybrid-SMP technology at up 1.2GHz
Architecturally matched ARMv7 Low-Power Mobile (LPM) processor optimized with Hybrid-SMP technology for extended battery life
Dual-channel independent memory controllers (LPDDR2 or DDR3/DDR3L)
Multiple power islands, dynamic voltage/frequency scaling, clock and power gating and standby modes
Powerful hardware accelerators for 2D/3D graphics, 1080p video, HiFi audio codecs and camera ISP
Dedicated security engine with hardware keys, secure memory and ARM® TrustZone® for secure boot and cryptographyMarvell’s Avastar 88W8787 delivers the wireless performance and range that will make the XO 4.0 a connected learning experience. Designed for both simultaneous and independent operation of the following:
IEEE 802.11a/g/b and 802.11n payload data rates for Wireless Local Area Network (WLAN)
Bluetooth 3.0 + High Speed (HS) (also compliant with Bluetooth 2.1 + EDR)
FM transmit and receive (digital encoder/decoder FM radio with RDS/RBDS)
The device supports the 802.11i security standard through implementation of the AES/CCMP, WEP with TKIP, AES/CMAC, and WLAN WAPI security mechanisms
