| Abstract: | A deflate decompressor includes at least one decompressor unit, a memory
access controller, a feedback path, and an output buffer unit. The memory
access controller is coupled to the decompressor unit via a data path and
includes a data buffer to receive the data stream and temporarily buffer
a first portion the data stream. The memory access controller transfers
fixed length data units of the data stream from the data buffer to the
decompressor unit with reference to a memory pointer pointing into the
memory buffer. The feedback path couples the decompressor unit to the
memory access controller to feed back decrement values to the memory
access controller for updating the memory pointer. The decrement values
each indicate a number of bits unused by the decompressor unit when
decoding the fixed length data units. The output buffer unit buffers a
second portion of the data stream after decompression. |
