ARM Models: Carbon Inside

ARM Models: Carbon Inside
by Paul McLellan on 05-01-2012 at 10:00 pm

ARM used to build their own models. By hand. They had an instruction-set simulator (ISS) called ARMulator that was largely intended for software development, and cycle-accurate models that were intended to run within digital simulators for development of the hardware of ARM-based systems.

There were two problems with this … Read More


Smart mobile SoCs: Apple

Smart mobile SoCs: Apple
by Don Dingee on 04-29-2012 at 9:00 pm

Apple sells devices. Lots of them. Their success is due to many things related to design and tech religion, and an important part is the SoC inside those devices which creates the experience people want. The official Apple information on their parts is minimal. Their SoCs have been dissected with more fervor than Roswell aliens.… Read More

Chris Rowen, Tensilica’s CTO, presented in Santa Cruz at the Globalpress briefing. He was basically presenting Tensilica’s audio strategy, which I’ve written about before. But he provided an interesting perspective. Globalpress (which flies journalists in from all over the world and then fills the few… Read More

TI has parlayed its heritage in digital signal processing and long-term relationships with mobile device makers into a leadership position in mobile SoCs. They boast a relatively huge portfolio of design wins thanks to being the launch platform for Android 4.0. On the horizon, the next generation OMAP 5 could change the entire… Read More

There are few companies that impact the overall mobile supply chain more than Samsung. They are one of Apple’s largest suppliers, fabbing the processor and LCDs in the iPhone and iPad. They also design and fab the Exynos SoC at the heart of their own Galaxy line of phones and tablets.… Read More


The Carbon Decade

The Carbon Decade
by Paul McLellan on 04-19-2012 at 6:00 am

Carbon Design Systems celebrates its 10th anniversary this month. It is a celebration that the company has survived a decade but also bittersweet that the company hasn’t been acquired for a juicy premium. But we just have to accept that EDA is not a business where you can throw together a company in 18 months and sell it for $1B… Read More

I went to part of the Linley Tech Mobile Conference. This is the current incarnation of what started life as Michael Slater’s Microprocessor Report, and the twice-yearly Microprocessor Forum. These very technical analysis organizations seem to work well when they are a small group of analysts working together to cover… Read More

I wrote on Monday about ARM’s Processor Optimization Packs (POPs). In Japan they announced yesterday the Seahawk hard macro implementation in the TSMC 28HPM process. It is the highest performance ARM to date, running at over 2GHz. It is a quad-core Cortex A15.

The hard macro was developed using ARM Artisan 12-track libraries… Read More


Making your ARMs POP

Making your ARMs POP
by Paul McLellan on 04-16-2012 at 6:30 am

Just in time for TSMC’s technology symposium (tomorrow) ARM have announced a whole portfolio of new Processor Optimization Packs (POPs) for TSMC 40nm and 28nm. For most people, me included, my first question was ‘What is a POP?’

A POP is three things:

  • physical IP
  • certified benchmarking
  • implementation knowledge

ARM big.LITTLE Virtual Platforms

ARM big.LITTLE Virtual Platforms
by Paul McLellan on 04-03-2012 at 7:11 pm

You have probably heard something about ARM’s big.LITTLE architecture. This links a Cortex-A15 multi-core CPU with a Cortex-A7 CPU. The A15 is a high-performance processor and the A7 is a very low power processor. The basic idea is that when high-performance is required (playing a graphical video game on your smartphone,… Read More
