Abstract: Embodiment herein provide a Bose-Chadhuri-Hocquenghem (BCH) encoder for generating a BCH signal. The BCH encoder (1) includes a memory for storing a minimum distance to be used for generating the BCH signal for a BCH code (n, k) and a polynomial generator for generating a generator polynomial for the BCH code (n, k) and encoding the generator polynomial to obtain the BCH signal. The polynomial generator includes a set of k registers (4) connected in series to receive the information bits and output an encoded bit based on a clock signal, a first gate (5) to receive a code length, a number of information bits, and the minimum distance as input, a second gate (6), and a finite field adder circuit (7) for determining a finite field sum of the output of each register of the set of k registers (4).

Abstract: Methods and system to control the data processing workflows in distributed environment with asynchronous message driven mechanism. A production workflow includes an ordered sequence of tasks to be executed that needs to be distributed on multiple computational nodes. Each task is assigned by a sender application to a receiver application running on a computational node through a message. On receiving the message, the receiver application sends and sends an acknowledgment to the message and schedules the sub tasks associated with the task. The sender application on receiving the acknowledgment removes the message from the queue otherwise the messages are stored in the database. On completion of the sub tasks the receiver application generates a message and the sender application on receipt of the message takes up the next task in the sequence and generates a message to another application. The sender application keeps on generating messages till all the tasks are completed in the sequence. The methods adopted in this invention provides persistence and guaranteed delivery of messages thereby improving the quality of service in transaction processing systems that are managing complex workflows.

Abstract translation: 用异步消息驱动机制控制分布式环境中数据处理工作流的方法和系统。 生产工作流程包括需要执行的有序序列的任务，需要分布在多个计算节点上。 每个任务由发送者应用程序分配给通过消息运行在计算节点上的接收者应用程序。 在接收到消息时，接收方应用程序发送并发送确认消息，并调度与该任务相关联的子任务。 接收到确认的发送方应用程序会从队列中删除该消息，否则将消息存储在数据库中。 完成子任务后，接收方应用程序生成一条消息，接收到该消息的发件人应用程序将占用该序列中的下一个任务，并向另一个应用程序生成一条消息。 发件人应用程序继续生成消息，直到所有任务按顺序完成。 本发明采用的方法提供持久性和保证的消息传递，从而提高正在管理复杂工作流的事务处理系统中的服务质量。
