OmniVision OA805 4K Video Camera SoC Supports 100 ms Boot Time, 4K HEVC Encoding

OmniVision OA805 Arm Cortex-A5 4K video camera processor is specifically designed for battery operated security and surveillance cameras, including video doorbells, with the ability to encode 4K30p video streams with HEVC/H.265 video codec at very low power consumption. The processor also has a very short boot-up time of just 100ms, meaning it can go from completely powered off to fully functional upon trigger by a motion detection sensor. That short boot time removes the need for standby or sleep mode further lowering the power consumption and allowing the camera to have up to two years of battery life (albeit no mention of battery capacity was made…). OmniVision OA805 specifications: CPU Main CPU – Arm Cortex-A5 processor with NEON, 32KB I-cache, 32KB D-cache Secondary CPU (SPU) – Arm Cortex-A5 processor with NEON, 32KB I-cache, 32KB D-cache Media Processing Unit (MPU) – 32-bit RISC MCU with 8KB I-cache, 8KB D-cache System Memory […]

AMLogic to Unveil M805 & S805 Quad Core Cortex A5 SoCs with Mali-450 GPU

As we are still waiting for retail availability of Android TV boxes and mini PCs based on AMLogic S802 quad core processor, rumors have started to surface about another quad core processor by the company called S805 to be used in media players, and probably it’s equivalent M805 for tablets. M803 and M805 were already part of AMLogic roadmap and were said to feature quad core CPU and GPU. It turns out M805 and S805 will feature four ARM Cortex A5 cores @ 1.5 GHz combined with a quad core ARM Mali-450 GPU (Mali-450MP2 ?). That means S805 will be cost down version of S802 with four cortex A5 cores instead of four Cortex A9r4 cores, and Mali-450MP2 instead of Mali-450MP6. The new processor will also support hardware decoded of H.265 @ 1080p, and embed a Gigabit Ethernet controller. If the features listed in the roadmap are still correct, we […]

VWorks VLAB Powers Freescale Vybrid Virtual Platform

Back in March, Freescale announced their Vybrid solution featuring both a Cortex A5 processor and a Cortex M4 microcontroller, and they had prototypes running an unnamed virtual platform in order to speed up software development and possibly have the software ready at the same time as the silicon is. Always looking to learn more, I studied and wrote about virtual hardware platforms such as Cadence Virtual System Platform, Wind River Simics Virtual Platforms and the open source Imperas OVPsim simulator. It turns out Freescale does not use any of these solutions, but relies on VWorks VLAB instead, which still use the same standard (SystemC/TLM) as the virtual hardware solutions aforementioned. VWorks uploaded a demonstration of VLAB running a virtual platform for the Freescale Vybrid controller and showing how it can handle both ARM Cortex-A5 and Cortex-M4 cores. This demo of VLAB 1.7.0 is pretty interesting and showcases: Dual (virtual) display […]
