RT-RK has abundant expertise in digital signal processing and more than 15 years of hands-on experience with designs that comprehend a full development cycle of DSP based systems.

ALGORITHM PORTING

However powerful and brilliant DSP algorithm is at the end of the day it should not on run on the last generation PC yet on a fancy device limited in resources (memory, CPU capabilities also with limited battery life). RT-RK provides a full port of in-house developed and customer provided algorithms on a range of embedded systems (DSP, CPU, FPGA) from various manufactures (TI, Intel, MIPS, ARM, Cirrus Logic).

OPTIMIZATION

It is often the case that customer has application properly working on a target environment but with inadequate performance. Customer R&D team has focused on development of new algorithms and algorithm proving. Algorithm is handed over to system integrators to be adapted to fit in the target SW/HW environment. In most cases the first team knows little (or does not care) about real time system requirements, whereas the second team knows little about algorithms. In these cases RT-RK specialists perform algorithm analysis, evaluate performance of the target SW/HW system, perform algorithm modification, code size and speed optimization in assembler and/or HLL language.
