TH22352A - The position processor for the signal processor. - Google Patents

Abstract

The invention involved a position processor for one signal processor. A pathway of calculating the position in read / write memory with at least one circular buffer. To store the condition variable Of digital filters It consists of a set (S) of registers. To store the overlapping positions (mod_pointer) then for each appropriate buffer at Correlates to the initial complete position of the buffer. In addition, the compute unit (+) is included to (1) add the current overlay position to the displacement (data_addr, write_addr) of the selected state variable relative to the position. Initiate the appropriate buffer (2) reduce the sum obtained from the step (1) with the appropriate buffer length (mod_numb) if the sum is greater than or equal to that buffer length and (3) add more. The starting position is buffered with the results obtained from step (2) to obtain the complete position of the selected state variable.
