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.
RT-RK is specialized in development of complete algorithms according to customer requirements, modification of existing algorithms (improvement, real time restrictions, platform requirements), and algorithm evaluation (performance evaluation, feasibility study — estimation of needed resources, platform/architecture proposal).
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 and 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).
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.
Verification and certification
Simplification of certification procedure tends to decrease inevitable human errors and to speed up the certification process. RT-RK offers the following services:
- Fully automatized pre-certification testing for 3rd party audio solutions
- Certification package, error-less installation of a complete testing environment for a certification house site: SDK, firmware, test cases, testing tools, board configuration, measuring devices and the like.
- Support during certification process
Highly important in most businesses are the tools of the trade. Development of the DSP solutions is no exception. In the past years we have created a complete tool chain for the several DSP platforms: assemblers, macro-assemblers and high-level assemblers, dynamic and static linkers, generic C compiler, high-speed instruction level compiled simulators, and Integrated Development Environment (IDE) based on the Eclipse framework.
Building of complete DSP systems
In complete DSP solutions we provide:
- HW design and prototyping (choice of appropriate DSP architecture, design of real time system based on selected DSP architecture, prototyping of the DSP system
- SW design and implementation (algorithm development, porting, optimization)
- Verification (verification of the requirements, verification of the algorithm implementation, verification of the final DSP system)
