Digital IP Library

Plextek maintain an internal library of in-house developed functions in order to allow us to quickly, reliably and cost effectively implement the complexity that modern design typically requires. Our Intellectual Property includes various implementations of numerous Digital Signal Processing functions, including:

Filters:

Real FIRs (eg Root Raised Cosine)

Complex FIRs (eg correlators, equalizers)

IIRs

Decimators

Interpolators

Adaptive Equalisers

FFTs

FEC building blocks:

Reed-Solomon codecs

Turbo coders

Viterbi

BCH codecs

CRC generators

Miscellaneous functions:

Modulators (QPSK, QAM16, QAM 64, BPSK, GMSK, etc)

Demodulators (QPSK, QAM16, QAM 64, BPSK, GMSK, etc)

Upconverters

Downconverters

Complex multipliers

CORDIC

FIFOs

UARTs

I2C (master and slave)

PCMCIA interface

PCI

These building blocks are implemented in synthesisable VHDL and are, in most cases, very portable thus allowing silicon vendor independence.

Even more important than our library of Intellectual Property is our knowledge of how to apply it. We have found that many designs require similar, but not identical, blocks of IP. We are able to customise our IP in order to provide a design implementation optomised for throughput or size, in order to best meet the needs of the application.

Our thorough knowledge of programmable logic technology and associated design methods (and tools) allows us to design solutions that are implemented efficiently in silicon, yet written in a manner to allow ongoing support, development and evolution. Please contact us with your requirements.
