Memory Mapping Method for Teaching in Reed Solomon Forward Error Correction System in AAL Type 1

摘要

The present invention comprises a first step (S1) of inputting RS encoded data from an RS encoder to a standby state; Determining whether a virtual path identification number (VPI) and a virtual channel identification number (VCI) are determined for the RS encoded data and maintaining the idle state of the first step (S1) if the virtual path identification number (VPI) and the virtual channel identification number (VCI) are not determined; A third step S3 of recording an ATM cell header at the top of the teaching block of the memory when the virtual path identification number VPI and the virtual channel identification number VCI are determined as a result of the determination in the second step S2; A fourth step (S4) of recording a SAR header at the top of a teaching block of the memory; A fifth step (S5) of reading the RS encoded user data and sequentially recording the user data in the horizontal direction on the teaching block; A sixth step (S6) of sequentially reading and outputting the ATM cell header, SAR header and teaching block recorded in the memory in the longitudinal direction; If there is data to be transmitted, it is determined whether there is data to be transmitted, and a seventh step (S7) of performing the fifth step (S5) and terminating the data transmission if there is no data to be transmitted .
