PulseDSP makes DSP product implementations as cost-effective as a fixed ASIC solution, effectively providing the programmability for free.
RadioScape's PulseDSP, which addresses the increasing computation complexity of today's wireless and multimedia applications, is a fully synthesisable parallel processor that works in harmony with existing cores on a single chip to produce a system capable of extremely high processing throughput at low power.
It provides faster time to market for programmable signal processing acceleration products, and allows developers to reconfigure their DSP functions as needed, allowing never before offered flexibility.

Toolset accelerates 3G development
RadioScape has announced the worldwide availability of the RadioLab 3G 2.0 system-level design toolset.
The core's performance is an order of magnitude better than existing DSPs, and is efficient in chip area and power consumption.
"RadioScape recognises that field-programmable DSP technology is key to successful implementation of next-generation systems.
Our 'soft core' makes it accessible to a larger community of customers", said Andrew Dewhurst, CTO of RadioScape's Systolix PulseDSP group.
"We have designed our technology specifically for the embedded market to integrate and verify it within a larger system, and so it does not introduce new and painful issues into the already demanding ASIC development process".
The synthesisable version of RadioScape's PulseDSP is a result of joint collaboration between RadioScape and Systolix, a DSP licensable core provider, which RadioScape acquired in January 2002.
The integration of Systolix's solutions into RadioScape's technology portfolio addresses the increasing need for targeted programmable parallelism required by next-generation basestation and multimode wireless user equipment (eg GSM/W-CDMA).
The fusion of these solutions enhances RadioScape's Layer-1 solutions for 3G designers trying to meet time, feature and cost targets.
"RadioScape's PulseDSP offers wireless baseband developers incredible flexibility and performance efficiency.
It is a 'must have' building block for demanding signal processing applications like 3G", said Robin Shephard, worldwide head of sales and marketing at RadioScape.
"We are committed to offering best-in-class software and hardware technology to accelerate the development of Layer-1 wireless systems with an emphasis on meeting competitive price-performance challenges".
In addition to its focus on Layer-1 wireless systems, RadioScape's PulseDSP is optimised for demanding arithmetic and signal processing functions.
Additional targeted applications include software radio, medical imaging, radar, multimedia and test and measurement systems.
RadioScape's PulseDSP soft core provides licensees a configurable and scalable architecture with performance up to 200 GMACs, 16bit fixed-point operations at 0.15um.
PulseDSP licensees benefit from a unique package of tools to ensure flexible integration into industry standard implementation flows.
The Systolix Design System (SDS) supports automatic core generation to users specifications using a 'wisard-like' core generator.
The built-in device independent compiler allows customers to develop designs on generic cores, and then supports evaluation of these designs across a range of targeted systems.
The tool flow produces independent, accurate HDL and C models of the complete core to allow detailed presilicon simulation and verification, allowing for the evaluation of target designs on a large number of possible cores before committing to a final specification.
PulseDSP has applicability to a number of DSP functions, including, filtering, decimation, interpolation, gain control, mixing, correlation, convolution, FFT/DCT, equalisation, mixing, linearisation and channel (de)coding.
It also works in harmony with existing cores on a single chip to produce a system capable of extremely high processing throughput at low power.
With existing feature sises of 0.15um and below, 20-200 GMAC per second is attainable in 16-32bit fixed-point precision.
This is an order of magnitude better than existing "state-of-the-art" von Neumann DSPs.
RadioScape is demonstrating its PulseDSP solution this week at the Embedded Systems Conference in San Francisco, on Booth 1837.
