Dynamically Structured Codes
نویسنده
چکیده
The characteristic property of dynamically structured code is that relations between elements of executable code are established at run-time. The word "structured" underlines that these relations must be in some kind regular. What these relations must and/or may be is a subject for studies. We expect that the use of dynamically structured codes will allow to reduce the complexity of software and thus improve its safety and reduce its cost. The paper discusses dynamically structured codes in general and proposes three new techniques. Two of them are improvements of the method of data execution (data-driven approach): execution of data with a customized method of execution, and joint compilation of two data sets into a single data set (and execution of the joint data set). The third technique — dynamic construction of call hierarchy (DCCH1) — may be used when we need to process a set of records having a complex format (examples: loading an object module, disassembly, instruction set emulation). DCCH1 is a regular way to build for each such record a customized code that will process that record.

Polar Code Construction for List Decoding
A heuristic construction of polar codes for successive cancellation list (SCL) decoding with a given list size is proposed to balance the trade-off between performance measured in frame error rate (FER) and decoding complexity. Furthermore, a construction based on dynamically frozen bits with constraints among the ”low weight bits” (LWB) is presented. Simulation results show that the LWB-polar ...
متن کاملSystems analysis and design of dynamically coupled multiscale reactor simulation codes
Chemical reacting systems involve phenomena that span several orders of magnitude in time and length scales, from the molecular to the macroscopic. To account for the multiscale character of these processes, many papers have adopted a simulation architecture that employs coupled simulation codes, in which each code simulates the physicochemical phenomena for a different range of length scales i...

PSD (Programmable Structured Document) is a framework in which structured documents are edited efficiently and safely by evaluating embedded codes in themselves. Justsytem’s xfy has a technology called Vocabulary Connection, which supports creating and editing source XML documents on the HTML view. Combining these two technologies allows us to produce an environment to support creating XML-base...
متن کاملProviding Secrecy With Structured Codes: Tools and Applications to Two-User Gaussian Channels
Recent results have shown that structured codes can be used to construct good channel codes, source codes and physical layer network codes for Gaussian channels. For Gaussian channels with secrecy constraints, however, efforts to date rely on random codes. In this work, we advocate that structured codes are useful for providing secrecy, and show how to compute the secrecy rate when structured c...
متن کاملAdaptive Soft-Decision Iterative Decoding Using Edge Local Complementation
We describe an operation to dynamically adapt the structure of the Tanner graph used during iterative decoding. Codes on graphs– most importantly, low-density parity-check (LDPC) codes–exploit randomness in the structure of the code. Our approach is to introduce a similar degree of controlled randomness into the operation of the messagepassing decoder, to improve the performance of iterative de...
