Command processor with multiple string copy engines for a decompression system

A method for decompressing compressed data to recreate original data from which the compressed data was generated in an electronic device that includes a first string copy engine and a second string copy engine, the method comprising:

• processing, by the first string copy engine, a first string copy command by:
• acquiring a first string from recreated original data;
• and
• appending the first string to the recreated original data;
• and
• processing, by the second string copy engine, a second string copy command by:
• checking the second string copy command for a direct dependency on the first string, a direct dependency occurring when the second string copy command is to acquire bytes from the first string, and, when the direct dependency is found, stalling further processing of the second string copy command until the first string copy engine has appended a corresponding portion of the first string to the recreated original data;
• acquiring a second string from the recreated original data;
• and
• appending the second string to the recreated original data.
