Title: Method for calculating of ac-3 decoder
Inventor: BAEK GEUN WOO
IPC: H03M7/00
Filed: 1998-10-09
Abstract: PURPOSE: A method for calculating of an AC-3 decoder is provided to adjust the size of a buffer for calculating by using N/2 buffers instead of using N buffers in calculation. CONSTITUTION: A method for calculating of an AC-3 decoder includes a first and a second tep. The AC-3 decoder includes a controller, an IDCT, a CIFFT, a first buffer and a second buffer. The controller controls a calculation operation of a frequency domain coefficient value by a time domain data sample. The IDCT calculates by applying a reverse conversion formula from the data of a conversion coefficient buffer according to the control of the controller. The CIFFT performs a CIFFT in a value calculated at the IDCT. The first buffer makes the calculated value at the CIFFT by storing. The second buffer stores the result calculated at the CIFFT. The first step is to store N time domain data in the first buffer, to calculate the frequency domain coefficient value by using the stored N time domain data, and to repeatedly store the calculated result in the second buffer until when a predetermined condition is achieved by comparing the N value with the second buffer's column information. The second step is to transfer the N/2 data to the block using the second buffer when the compared result achieved the predetermined condition.
