| MimoOn Fields LTE Software for Multiple Processor Vendors |
By BDTI, 9/2/2010
 With the growth in mobile data traffic, there is increasing interest in fourth-generation (4G) cellular technologies, especially the Long Term Evolution (LTE) of the 3rd Generation Partnership Project (3GPP) – the successor to GSM/EDGE and UMTS/HSxPA technologies. LTE has gained a decided momentum advantage over WiMax and is expected to be the most important 4G technology. BDTI recently spoke with mimoOn, a company headquartered in Duisburg, Germany that licenses LTE software for both terminals and base stations. mimoOn was founded in 2006 by Thomas Kaiser, a researcher from University of Duisburg-Essen. mimoOn currently employs about 50 people, including wireless experts with backgrounds at companies such as BenQ, TTPCom, and Nokia.

| Texas Instruments’ Graphical Programming Tool Generates Prototyping Code |
By BDTI, 9/2/2010
 Texas Instruments (TI) recently introduced C6EZFlo, a graphical programming tool for its C6000 and DaVinci DSP families. C6EZFlo is a prototyping tool to help users quickly develop initial software implementations of their applications. In particular, C6EZFlo is designed to help programmers develop initialization, configuration, and framework code for their applications. C6EZFlo generates C code and project files intended to be loaded into TI’s C language Code Composer Studio tool suite for further development.

| Jeff Bier's Impulse Response— The Last One-Man Dog? |
By Jeff Bier, 9/2/2010
What’s a “one-man dog,” you ask? It’s a dog that works for one person and one person only. (It’s also the title of a 1929 movie about a dog that solves a murder mystery, but that’s a story for another day.) What does this have to do with embedded processing or DSP, you ask? Well, I use the phrase “one-man dog” to refer to a processor architecture that is captive to a single semiconductor vendor.

| Case Study: Patent Litigation Support |
By BDTI, 9/2/2010
These days it’s not uncommon to see patent infringement claims settled for hundreds of millions of dollars. There was RIM’s settlement with NTP for $612 million, Intel’s with Intergraph for $600 million and with MicroUnity for $300 million, and the blockbuster, Qualcomm’s settlement with Broadcomm for $891 million. These huge sums stimulate the equivalent of high-tech ambulance-chasing: individuals and companies pursuing patent infringement claims against companies with deep pockets, seeking substantial settlements. Whether the claims of infringement are valid or not, technology companies need to ensure they are equipped to defend themselves.

| Xilinx Announces Next-Generation 28 nm FPGA Families |
By BDTI, 7/29/2010
 Xilinx recently announced its next-generation “7 series” FPGAs, featuring new power-saving features as well as increased capacity and performance. The series will be composed of three chip families, all fabricated in TSMC’s high-k metal gate (HKMG) 28 nm technology. All three families will use the same logic cells, block RAMs, DSP slices, and I/O cells. Compared to existing 40 nm Xilinx devices, Xilinx claims that, in typical applications, the new FPGAs will reduce power consumption by 50, deliver the same performance at 50% lower cost, or offer twice the performance in a single chip. The forthcoming ARM-based CPU-FPGA platform described here will be part of the new 7 series FPGAs.

| ARM Introduces Cortex-M4 Core for Digital Signal Controllers |
By BDTI, 7/29/2010
 This spring, ARM added the Cortex-M4 digital signal controller (DSC) to its processor core line-up. This product brings digital signal processing capabilities to ARM’s microcontroller core line (the Cortex-M family). At the Embedded Systems Conference in San Jose in April, NXP demonstrated a prototype Cortex-M4-based chip running at approximately 150 MHz. In June, Freescale announced its Kinetis line, also based on the Cortex-M4. ST Micro and Texas Instruments have also announced their intentions to use the Cortex-M4.

| Case Study: Benchmarking PowerPoint Processors |
By BDTI, 7/29/2010
Processor designers know that a cycle-accurate simulator can be used to benchmark a processor that has not yet been fabricated. But many designers don’t realize that it’s also possible to benchmark an idea for a processor, a processor that may exist only in PowerPoint slides—and that there are good reasons for doing so.

| Octasic Announces Video and Wireless Processor Chips |
By BDTI, 6/29/2010
 Octasic Semiconductor recently announced the OCT2200 family of multi-core DSP processors based on its Opus clockless (asynchronous) DSP core. The OCT2224M is intended for media processing equipment including video conferencing systems, internet video streaming and transcoding, and video surveillance. The OCT2224W is designed for wireless applications, notably smaller basestations such as femtocell, picocell, and low power basestations. According to Octasic, it can support GSM, EDGE, HSPA, WiMAX and LTE standards. Octasic, headquartered in Montreal, was founded in 1998 with an emphasis on voice digital signal processing.
