133 In addition to these modules we need overall control, marker generation,
153 We also need overall control, marker parsing, and a data source module.
241 *** Overall control structure ***
243 We previously mentioned the need for overall control logic in the compression
245 control was mostly provided by "pipeline control" modules, which proved to be
247 control logic has been subdivided into multiple modules. The control modules

265 control code need only be concerned with decisions that affect more than
268 2. Data buffering control. A separate control module exists for each
282 A data buffer control module may itself be viewed as a processing step by a
283 higher-level control module; thus the control modules form a binary tree with
286 The control modules are objects. A considerable amount of flexibility can
287 be had by replacing implementations of a control module. For example:
