H.264 Makes Encoding Easier

Speaking at a red carpet interview during the recent Streaming Media East conference in New York City, Jan Ozer, an expert on encoding for the web, see the rise of the H.264 codec on the fractured landscape of devices, formats, and codecs, offering video has gotten easier.

"Things have actually gotten better over the last year, because the H.264 standard has become the focal point of technologies that can actually take an H.264 stream and transmux it, which basically means put it in a different container format, for multiple targets," said Ozer. Wowza Media Server 2 was the first tool he saw that could do that, he added.

"If you're producing today, typically your high-level challenges are, number one, I need a desktop technology, and that can be Flash or Silverlight, and number two, I want to hit iDevices, and number three, then you'll start to look at the other mobile devices out there," said Ozer.

No longer having to encode separately for the desktop and Apple iOS devices has been a big time-saver.

Cadence acquires power specialist Azuro

Cadence Designs Systems Inc. has moved to strengthen design tools it provides to customers developing next-generation SoCs through the acquisition of power-focused Azuro Inc. According to Cadence press release, Azuro offers unique clock concurrent optimization technology, also known as ccopt, which delivers superior capabilities for designers faced with increasing performance, power and area challenges. Specifically, ccopt technology has delivered significant quality of silicon (QoS) on high-speed processor designs in the areas of:
  • Power (clock tree power reduction up to 30 percent and total power improvements of up to 10 percent),
  • Performance (improvements of up to 100 MHz for a GHz design), and
  • Area (clock tree area reduction up to 30 percent)

Bluespec June 2011 Release

Bluespec is an electronic system level (ESL) synthesis solution that addresses algorithms, control logic and complex datapaths. It includes compiler (BSC), simulator (BlueSim), development station (BDW), and emulation platform (emVM). The latest Bluespec version is 2011.04C (?).

It seems Sce-Mi has been improved in this version. Sce-Mi, the Standard Co-Emulation Modeling Interface, is an Accellera standard which was designed to aid in verification of hardware designs. The standard specifies a transaction-based modeling interface used to pass messages between an un-timed software test bench and a design under test (DUT) described in register transfer language (RTL). The DUT can be emulated on an FPGA to achieve better performance than software RTL simulators are capable of.

Core Technology

Bluespec Core Technology
Bluespec Compiler (BSC)Compiles a high-level model, transactor, test bench or implementation into Verilog RTL or SystemC
Bluespec Simulator (Bluesim)Simulates Bluespec designs 5X-20X faster than RTL
Bluespec Development Workstation (BDW)Provides a high-level GUI-based development environment for the design, analysis and debug of Bluespec designs
emVMProvides debug, instrumentation & co-emulation for easy emulation of synthesizable models and legacy RTL with third-party FPGA boards/emulators
