VOV on TMS320C54x DSPs

Processor Support

TMS320C54x Family

VOV is VINJEY's implementation of Ogg Vorbis I Decoder. Vorbis is general purpose perceptual audio codec from xiph.org foundation. It intends to allow maximum encoder flexibility, thus allowing it to scale competitively over exceptionally wide range of bit rates.

VOV is an independent implementation of Ogg vorbis decoder developed from scratch by VINJEY Software, keeping in mind with the MIPS and Memory requirements of resource constrained embedded solutions. VOV has support for detecting and handling lost and errant packets in the input stream. VOV has an effective memory management algorithm, that ensure no dynamic memory allocation is required. VOV supports decoding of input streams with Floor0. Support for Floor0, can be enabled (Or) disable at compile time.

The C54x fixed-point DSP is based on an advanced modified Harvard architecture that has one program memory bus and three data memory buses. This processor provides an arithmetic logic unit (ALU) with a high degree of parallelism, application-specific hardware logic, on-chip memory, and additional on-chip peripherals. The basis of the operational flexibility and speed of this DSP is a highly specialized instruction set. Separate program and data spaces allow simultaneous access to program instructions and data, providing a high degree of parallelism. Two read operations and one write operation can be performed in a single cycle. Instructions with parallel store and application-specific instructions can fully utilize this architecture. In addition, data can be transferred between data and program spaces. Such parallelism supports a powerful set of arithmetic, logic, and bit-manipulation operations that can all be performed in a single machine cycle.
