DeviceGuru writes: Freescale has unveiled a new i.MX7 embedded processor family. The family launches with two parts having one or two Cortex-A7 cores, along with Cortex-M4 microcontroller cores, and boasts much lower power consumption than the company's popular i.MX6 embedded processors, making it ideal for power constrained Internet of Things applications. The i.MX7 is Freescale's second i.MX family to use Coretex-A7 cores, and its first to move backward in performance, although significantly upward in power efficiency — a testament to how IoT is impacting the semiconductor business. Like the recently introduced i.MX6 UltraLite, the initial i.MX7 parts are limited to 2D image processing in hardware. An ARMv8 Cortex-A53 based i.MX8 line is also under development, and is expected to be announced next year with 2016 or 2017 availability.

DeviceGuru writes: Freescale has announced three new versions of its popular i.MX6 SoCs, including new DualPlus and QuadPlus parts featuring enhanced GPUs and expanded memory support, and a new low-end, IoT focused 528MHz UltraLite SoC that integrates a more power-efficient, single-core ARM Cortex-A7 architecture. The UltraLite, which will be available in a tiny 9x9mm package, is claimed by Freescale to be the smallest and most energy-efficient ARM based SoC. It has a stripped-down WXGA interface but adds new security, tamper detection, and power management features. All the new Freescale i.MX6 SoCs are supported with Linux BSPs and evaluation kits.

Bunnie Huang is both a hardware and software hacker, but that's greatly understating the case: renaissance man is more like it. Bunnie doesn't just tinker with one-off system modifications or console mods (though he's done that, too) -- he creates and repurposes at scale. (He's also an author, respected researcher with interesting thoughts on a wide range of topics, like how to think of the H1N1 flu from the point of view of a security researcher.) Bunnie's latest long-term project has been mentioned a few times on Slashdot: It's an open-source laptop computer that goes much farther than some other open-source hardware projects, and as a bonus includes an FPGA as well as a conventional -- but unusual -- processor. (Bunnie grants that there are still bits that aren't quite open source, but points out that we also don't have the software that runs the fabs; there's a point of diminishing returns.) A crowd funding campaign (via CrowdSupply) was successful enough to also fund several stretch goals, including a general purpose breakout board. I talked with Bunnie at the recent Bay Area Maker Faire. (Expect more from that show in coming weeks.) He walked us through the state of the hardware, and talked about some of the design decisions that go into making a computer that is of, by, and for hackers. (Alternate video link)

eldavojohn writes "Last week, Freescale Semiconductor announced their i.MX508 chip and a few days ago released a rather bland and boring announcement that it's available. But there was at least one interesting line from that press release, 'The i.MX508 applications processor is expected to be priced at less than $10 (USD) in quantities greater than 250K units.' Yes, less than ten dollars. This sparked a wave of articles detailing how this new chip will allow the sub-$99 e-reader to emerge and according to market research, consumers are thirsty for something much more affordable than the Kindle."

Alchemist253 writes "The New York Times is running an article about a possible leveraged buyout of speciality chipmaker Freescale Semiconductor. Freescale currently makes a variety of embedded processors, microcontrollers, and memory, but is probably best known to the Slashdot crowd as the Motorola spinoff that supplied Apple its PowerPC chips before the shift over to an Intel architecture. From the article, "A consortium of investment firms was near a deal late last night to acquire Freescale Semiconductor... for more than $16 billion, according to people briefed on the negotiations. The deal, if completed, would be the largest leveraged buyout ever in the technology sector, surpassing the $11.3 billion sale of SunGard Data Systems last year.""

ThinSkin writes "Photon processors that transmit data via light, not electrons, are slated to enter production in mid-2006, ExtremeTech reports. Headed by a UCLA professor and a Nobel Prize winner, startup Luxtera claims that its optical modulator clocks in at 10-GHz, tens times that of Intel's optical modulator researchers talked about last year. Since the optical module exists as its own entity, it will require a standard CMOS processes to integrate the optical waveguides. Luxtera has worked closely with Freescale Semiconductor to develop this technology."

acsinc writes "The Register reports that Freescale (Motorola's chip division) has launched the 90nm G4, and is planning a dual core version for next year. The chip is faster -- over 1.5GHz -- and cooler than the old chip, but it is also pin compatible. This ought to help provide a speed bump for PowerBooks, which still don't have G5s."
