TL;DR: This paper will evaluate the new processor ADSP-21535 Blackfin from Analog Devices in terms of speech coding by thoroughly examining the fixed point source code from ITU, International Telecommunication Unions and by the instruction reference manual and the hardware reference guide.
Abstract: This paper will evaluate the new processor ADSP-21535 Blackfin from Analog Devices in terms of speech coding. Three speech coding algorithms has been studied, G.723.1, 6.3 kbit/s and 5.3 kbit/s and G.729 8 kbit/s. All these three algorithms are proposed by the H.323 standard together with G.711 64 kbit/s and G.728 16 kbit/s. I will discuss some important issues of these speech coding algoriths and compare them with the capabilities of Blackfin. The work has been done by thoroughly examining the fixed point source code from ITU, International Telecommunication Unions [1], [2] and by the instruction reference manual [3] and the hardware reference guide [4].
