ChannelScience has deep, practical knowledge of partial-response maximum-likelihood (PRML) sequence detection architectures and algorithms. We can help your team evaluate, design, optimize, understand, and use state-of-the-art PRML and iterative read channels and algorithms for magnetic disk and tape, optical disk and tape, Flash memory, MEMS, holographic media, and the new storage technology you are inventing right now.

Our flagship product, PRMLpro^TM, provides the industry with an independent system-level software tool for design, test, and evaluation of many key drive components and of the data storage device itself. Component suppliers evaluate and improve the performance of their products using PRMLpro^TM's system-level metrics such as bit error rate (BER), without the high cost of a large channel research staff. PRMLpro^TM has been completely re-designed and features a simpler user interface, direct loading of a variety of common digitizer and oscilloscope file formats, and a SOVA-based bit-level reliability metric.

PRMLpro^TM analyzes other types of time-series data beyond storage-based readback signals. For example, cardiac waveforms and sensor signatures have been analyzed with PRMLpro^TM.
