Texas Instruments Makes It Harder to Run Programs on its Calculators

Texas Instruments' graphing calculators have a reputation as hobbyist devices given their program support, but they just lost some of their appeal. Cemetech has learned (via Linus Tech Tips) that Texas Instruments is pulling support for assembly- and C-based programs on the TI-84 Plus CE and its French counterpart, the TI-83 Premium CE. Install the latest firmware for both (OS 5.6 and OS 5.5 respectively) and you'll not only lose access to those apps, but won't have a way to roll back.

The company explained the move as an effort to "prioritize learning and minimize any security risks." It's to reduce cheating, to put it another way... While this could please teachers worried that students will use apps to cheat during exams, enthusiasts are unsurprisingly mad. This reduces the amount of control programmers have over their calculator apps.

There has been some brainstorming in the past few days among community members about (for lack of a better name) the TI-84 Plus CE Developer Edition. If we were to float that idea to TI, perhaps a calculator clearly and visibly distinguished from the TI-84 Plus CE that could be used on tests, what would you want from it? Opened up for ASM, C, and Python programming? Having the same specs as the usual TI-84 Plus CE, or something else? Having more features to help you connect hardware to it? And considering that TI is (after all) a business, would you buy one, and how many others do you think would? Beyond the community, who else could it be marketed to? Why would someone choose to buy the Developer Edition over a standard TI-84 Plus CE? Why would TI benefit by having it?

Mobile TV heats up with Broadcom's 65-nm SOC

The official news is out!
Broadcom has just announced a monolithic digital CMOS mobile TV receiver/demodulator, that reduces power consumption by up to 40 percent and physical dimensions by up to 30 percent from current handset design budgets. Designed for global digital TV reception on portable devices, the BCM2940 chip supports VHF III, UHF IV and V bands. It also supports the EU/US L-bands and integrates a 4-Mb MPE-FEC SRAM to handle DVB-H parallel/consecutive streams and services. The chip offers various physical interfaces including SPI, SDIO and USB 2.0.

Ok that sound great and appetizing, but is there a Market really?
Sometime ago TI came up with its own single-chip DVB-H receiver, called the Hollywood using a 90-nm technology, but the company hasn't announced any major design wins.
ST put its project on the back burner more than a year ago.
Now noise from NXP or Infineon!!!!!!!

Infineon given it recent track record and recent aquisitions i would not be surprised if they throw one in pretty soon :-) it is more a speculation than prediction.
Lets wait and watch and do Read on... this article on EE Times..

TI reveals details of 45-nm process

Rumors had been rampant for the past 3 months or so that TI had stopped development on the 45 nm node and moved on to 40nm attributing to lower power advantages and poor performance scaling till this article was published at EETimes.

"The first 45-nanometer chip to be designed by Texas Instruments, and fabricated by a foundry, uses new processing technology never before revealed by TI. The design details of the 45-nanometer process used to lower power by 63 percent and increase performance by 55 percent, compared with its 65-nanometer process, will be revealed Tuesday (Feb. 5) by TI at the International Solid-State Circuits Conference here."
