Abstract:
1. A circuit design method to control access pointers of different memory, which employs an (m+n)-bit read control signal circuit and an (m+n)-bit write control signal circuit to control the access pointers of a memory with 2 m -block, and each block has 2 n -register in order to perform buffer access of printers, comprising the following steps: retrieving the previous addresses of the read and write pointers; receiving a control signal from a data source; analyzing the control signal to extract a transfer mode, an access mode, and an access number; determining the control signal circuit (r transforming the access number to determine a memory block control circuit (r setting the access pointers pointing to the corresponding memory addresses of the memory block control circuit and the register control circuit; and performing a data access of the corresponding memory addresses.
