Tensilica ConnX BBE16 BaseBand Engine DSP

The ConnX BBE16, from Tensilica, is a second generation baseband engine for LTE (long-term evolution) and 4G baseband SOC (system-on-chip) designs. The ConnX BBE16 is an ultra-high performance 16-MAC fixed-point DSP engine. It is based on an 8-way SIMD (Single Instruction, Multiple Data), 3-issue VLIW (Very Long Instruction Word) architecture with two 128-bit load/store units. It is a click-box configuration option with the configurable Xtensa LX3 processor core. Designers can also choose from a number of other configuration options (memories, interfaces, etc.) when designing their core. The ConnX BBE16 and an evaluation kit will be available in the second quarter of 2010.

CEVA Application Optimizer for C-based Development of DSP Cores

CEVA launched the Application Optimizer, which is an integrated optimizing toolchain that enables an end-to-end, fully C-based development flow for licensable DSP cores. Available as part of the CEVA-Toolbox Software Development Environment, the Application Optimizer enables application developers to easily develop software for CEVA’s DSPs purely in C-Level, eliminating any hand-written assembly coding. This results in significantly better overall performance and a shorter design cycle for SoC designs.

Digital Signal Processing Theory Architecture and Algorithms Course

The Institute for System Level Integration and Steepest Ascent Ltd. will host a digital signal processing course at the Bath Innovation Centre on October 20-23, 2008. The 4-day intensive course will focus on digital signal processing, architectures, and algorithms. The event will provide attendees with a solid and intuitive understanding of the essential digital signal processing tools — such as digital filters, FFTs, correlators, adaptive systems, and multirate systems. The underlying theory, algorithms, and practical knowledge is then applied across a range of DSP applications including QAM/QPSK digital communications, time-frequency signal analysis, adaptive data equalisation, acoustic echo cancellers, multirate systems, and sigma delta coding.

The course comes at a time when DSP is increasingly being applied to more powerful general purpose microprocessors, field-programmable gate arrays, digital signal controllers and stream processors. It is suitable for all engineering, marketing and technical management staff. By delivering a sound grounding in DSP theory and practice, participants will leave with the knowledge required to apply DSL solutions to problems within their given domains.

BDTI Benchmarks for picoChip PC102 multicore-DSP

According to Berkeley Design Technology (BDTI) benchmarks, picoChip’s PC102 multicore signal processing device has a 40-fold advantage in price-performance over traditional DSP processors solutions in key communications benchmarks, and 8-times higher absolute performance.

The BDTI Communications Benchmark (OFDM)(TM) shows that the PC102 picoArray(TM) can implement 14 benchmark channels in a single device running 160MHz. This represents a cost per channel of $6.78, some 40 times less than the figure for competing traditional DSPs.

The BDTI Communication Benchmark (OFDM) is designed to be representative of the signal processing workloads found in communications equipment for applications such as DSL, cable modems and wireless systems. It is intended to enable benchmarking and comparison of a wide range of devices on real-world, datapath-focused applications. Each channel of the benchmark is a representative model of an Orthogonal Frequency Division Multiplex (OFDM) modem, including filter, Fast Fourier Transform (FFT), slicer and Viterbi decoder.

The complex mathematical theory associated with digital signal processing is presented in an intuitive and straightforward style. The course is aimed at a wide audience reaching from scientists, engineers, project managers to even marketing staff. The following prior experience is useful but not essential: programming principles, electrical engineering principles, Bachelor level mathematics.

The training will feature presentations and design sessions. Special attention is paid to practical experience; each presentation is concluded by a hands-on session in which attendees will be able to simulate and implement the structures and architectures introduced. Each attendee will receive a comprehensive set of notes and examples for in depth study after the course.
