The Mediabench suite [ ^[150]] is a set of multimedia benchmarks that can be considered a de-facto standard for multimedia applications. All the applications are public domain and derive from image processing, communication and DSP applications. The suite is composed of the following applications:

G.721 Voice Compression encoder and decoder:

These applications consist of the reference implementations of the CCITT (International Telegraph and Telephone Consultative Committee) G.711. G.721, and G.723 voice compressions algorithms.

Ghostscript:

This application is an interpreter for the PostScript language characterized by a very high I/O activity but no graphical display.

Mesa:

Mesa is a 3D graphics library very similar to OpenGL. Among the available applications using this library we selected osdemo, which executes a standard rendering pipeline.

MPEG decoder:

This is an implementation of an MPEG2 decoder, a standard for high-quality digital video compression, based on the inverse discrete cosine transform.

PGP encoder:

PGP is digital signature and encryption application based on "message digests", i.e, 128-bit cryptographically strong oneway hash value of the message. Data encryption is based on the RSA asymmetric encryption scheme.

RASTA:

This application performs speech recognition by means of speech analysis techniques such as PLP, RASTA, and Jah-RASTA.

ADPCM encoder and decoder:

Adaptive differential pulse code modulation filters for audio coding.

EPIC encoder and decoder:

Image compression/decompression fixed point tools based on a bi-orthogonal wavelet decomposition, combined with a run-length/Huffman entropy coder.

GSM encoder and decoder:

European GSM 06.10 standard speech transcoders based on residual pulse excitation/long term prediction...
