Appl. No.:

11/239710

Eric Pan - Irvine CA, US

Assignee:

Via Technologies, Inc. - Taipei

International Classification:

G08C 15/00
H04L 12/46
H04L 12/54

US Classification:

370232, 370235, 370412, 370429

Abstract:

A mechanism is disclosed for imposing a delay on a variable rate information stream. A stream of information sets is received, where the stream has a variable information rate that can change from time period to time period. In a first time period, information sets are stored into a first buffer. In a second time period, information sets are stored into a second buffer. Because of the variable information rate, the number of information sets stored into the first and second buffers may differ. After a delay period has elapsed since the beginning of the first time period, the information sets in the first buffer are outputted. After a delay period has elapsed since the beginning of the second time period, the information sets in the second buffer are outputted. In this manner, a consistent delay is imposed on the information sets regardless of the information rate of the stream.

Abstract:

An apparatus, spread spectrum receiver, and method of controlling a circular buffer, comprising a circular buffer and a controller coupled thereto. The circular buffer receives first data at a first data rate and second data at a second data rate. The controller determines a first range in the circular buffer based on the first data rate and a first time difference between the first write and first read speed, accesses the first data in the first range, estimates a second range in the circular buffer based on the second data rate and a second time difference between the first write and first read speed, and accesses the second data in the second range, where the second range is larger than and partially covered by the first range.
