The Oregano Systems 8051 IP core offers faster program execution compared to the original 8051 devices since we have optimized the processor’s architecture. Additionally, the 8051 IP core offers some sort of parametrize ability. The Oregano Systems 8051 IP Core is available free of charge even for industrial applications under the LGPL (Lesser General Public License).
The ADPCM (Adaptive Differential Pulse Code Modulation) algorithm performs speech compression of 64 kbit/s PCM data. The algorithm is standardized as ITU Standard G.721 and G.726.
