Media Player SoCs at CES 2014 – Qualcomm Snapdragon 802 and Sigma Designs SMP8756

Apart from Nvidia Tegra K1, CES 2014 has been somewhat disappointing when it comes to new mobile SoCs announcement. On the media processor front, we’ve had Marvell announces Skyworth Android TV set-top boxes and HDTV based on their ARMADA 1500 Plus SoC, and we’ve got at least two new processors for media players with Qualcomm Snapdragon 802, and Sigma Designs SMP8756. Let’s have a look at some of the details. Qualcomm Snapdragon 802 Qualcomm has started to enter the media player space with MPQ8064 / 8064M last year, but I haven’t seen actual products based on this SoC, except Qubi, which is not shipping yet. This year, the company announced Snapdragon 802 SoC designed for next-generation smart TVs, smart set-top boxes and smart digital media adapters. As usual, the company gave very little details in the press release, but here’s what we know: Quad core Krait processor @ 1.8Ghz with […]

What to Expect from AllWinner, Rockchip, Mediatek, and Other Silicon Vendors at CES 2014

CES 2014 is coming soon, and it will take place on 7 – 10 January, 2014, and we can expect some interesting SoC news. Samsung suggested they will unveil their 64-bit ARM SoC (Exynos 6?) at CES 2014, Nvidia will hold a press conference to “showcase new NVIDIA Tegra mobile technologies, gaming innovations, and advanced automotive display technologies”, and Qualcomm has been quiet for now. However, several Chinese SoC vendors, namely AllWinner, Rockchip, and Mediatek, have already announced what they will showcase at CES 2014, albeit with few details. AllWinner at CES 2014 Allwinner announced will showcase their OptimusBoard based on their Ultra Octa-Core A80 SoC, as well as 4G tablets powered by Allwinner A31/A31s, and dual-SIM phablets sporting A23 dual-core. Allwinner A80 is an Octacore processor featuring four ARM Cortex A7 cores, and four Cortex A15 cores @ 2.0GHz together with an unnamed GPU offering 2x more performance over previous […]

Raspberry Pi Releases BCM2835 Datasheet for ARM Peripherals

If you have been following Raspberry Pi project, you may have noticed the dearth of documentation related to Broadcom processors. For BCM2835 (The processor used in Raspberry Pi board), Broadcom only has one laconic webpage. But the Raspberry Pi’s “super-team” has managed to get a (partial) datasheet for the SoC showing the details of BCM2835 ARM peripherals which is all that we may need. This would only be useful for people playing around with the Linux (and u-boot) drivers. The document includes details about the processor’s memory map as shown below. It also contains details (registers, implementation details, etc..) about the following ARM peripherals: Timers Interrupt controller GPIO USB PCM / I2S DMA controller I2C master I2C / SPI slave SPI0, SPI1, SPI2 PWM UART0, UART1 You can download BCM2835 datasheet to get the complete documentation. The Raspberry Pi foundation also announced that the boards will be ready on February […]

ARM Unveils Cortex-A7 and big.LITTLE processing

ARM unveiled the Cortex A7, a new core with higher performance than the Cortex A8 (1.5x) and with 5 times less power consumption. It will be used in conjunction with Cortex-A15 Core and allows big.LITTLE processing where the Cortex A7 (companion core) takes care of the low performance, low power tasks (social network, email, SMS, phone calls) and the Cortex A15 kicks in for high performance tasks such as video processing and gaming. Here’s an excerpt of the Cortex A7 / big.LITTLE processing press release: ARM today announced the ARM® Cortex™-A7 MPCore™ processor – the most energy-efficient application class processor ARM has ever developed, and big.LITTLE processing – a flexible approach that redefines the traditional power and performance relationship. The Cortex-A7 processor builds on the low-power leadership established by the Cortex-A8 processor that is at the heart of many of today’s most popular smartphones. A single Cortex-A7 processor delivers 5x […]
