MPPC-C Version 3 Data Compression Software Hi/fnTM supplies two of the Internet’s most important raw materials compression and encryption. Hi/fn is also the world’s first company to put both on a single chip, creating a processor that performs compression and encryption at a faster speed than a conventional CPU alone could handle, and for much less than the cost of a Pentium or comparable processor.

MPPC-C Version 3 Data Compression Software

Product Description

The MPPC-C Data Compression Software Library provides a processor independent software implementation of the MPPC algorithm in a C source code format. The software is compatible with ANSI C.

This library supports the simultaneous use of multiple compression and decompression histories. Each history is completely independent of other histories. In addition, this software is re-entrant.

MPPC-C is fully compatible with Hi/fn’s data compression processor chips that support the MPPC algorithm. Files compressed or decompressed with MPPC hardware or software may be compressed or decompressed interchangeably with MPPC hardware or software
• MPPC compression format
• Multiple history support
• NT compatible

MPPC-C Files

The MPPC-C library is composed of several files. They are summarized below:

MPPC.H - This header file contains the function prototypes and constant definitions. This header file should be included in all source modules that access the MPPC-C library.

MPPCC.C - This source file contains the functions required for the compression operations.

MPPCD.C - This source file contains the functions required for the decompression operations.

Function Summary

Functions related to data compression are:

MPPC_SizeOfCompressionHistory - Returns amount of memory required for each compression history.

MPPC_InitCompressionHistory - Initializes a compression history.

MPPC_Compress - Compresses a block of data.
