| VeriSilicon Buys ZSP Unit from LSI Logic |
By BDTI, 7/19/2006
 On July 5th ASIC design house VeriSilicon Holdings Co. announced its acquisition of the ZSP digital signal processor core business from LSI Logic for $13 million in cash and stock (LSI originally acquired the ZSP unit in 1999 for $11.3 million). The acquisition includes cores, development tools, ASSPs, software, and associated patents. VeriSilicon will retain most of the ZSP R&D team and continue developing a roadmap for additional core products.

| TI Introduces 8-Channel Audio Processor for Multi-Channel Audio |
By BDTI, 7/19/2006
 On June 26th Texas Instruments announced the TAS3108, a new 8-channel audio processor targeting high fidelity home and car audio. The TAS3108 contains a relatively simple fixed-point DSP core running at 135 MHz, coupled with an 8051 microprocessor that handles I/O and control operations. The DSP core, with one 28x48-bit multiplier, a 76-bit accumulator, and dither generator, is highly specialized for algorithmically simple filtering tasks such as FIR and IIR filters, mixing, equalization, and dynamic range compression.

| Case Study: Algorithm IP Companies Focus on the Algorithm |
By BDTI, 7/19/2006
Companies that focus on DSP algorithm development are often at the cutting edge, delivering the ideas that drive new technologies. Unfortunately, it takes more than a great algorithm to be successful; an algorithm is only as good as its implementation. In this case study, BDTI examines software optimization techniques utilized for implementation of a video compression algorithm.

| Jeff Bier's Impulse Response – Multi-Core Math |
By Jeff Bier, 7/19/2006
Freescale recently introduced a new DSP chip, the MSC8144, that contains four 1 GHz SC3400 processor cores. Freescale characterizes the new chip as being "performance-equivalent" to one 4 GHz core. But is it really? As usual, the answer is, "It depends." It depends on what kind of application you're running, on how you map the application onto the cores, and on how you choose to characterize "performance."
