STORAGE SYSTEM FOR VARIABLE LENGTH DATA

摘要

PURPOSE:To improve the availability of a buffer memory by using a describer containing a storage area designating information describing part, a data dividing information describing part and a chain information describing part. CONSTITUTION:The buffer areas BA1, BA2... having each fixed size and stored in a buffer memory are connected with each other by a describer dD containing 1st and 2nd pointers PNT1 and PNT2. The head address of a buffer area storing the reception data of a single frame is described to the pointer PNT1; while the head address of a memory area storing a describer (DDi+1) following a describer DDi is described to the pointer PNT2 respectively. Furthermore the describer DD contains an instruction column DES which describes a data dividing mark showing whether the reception data is through or not within a buffer area instructed by the DD itself. Thus it is possible to improve the avilability of a buffer memory which stores the data on a variable length frame.
