Short Content: Digest: This article described in detail (Texas Instruments) C55x in the series DSP platform integrated in TI real-time realizes 0.3kbps to arrange the decoding algorithm to the 16kbps many kinds of speed pronunciations the method, and optimized the assembly directive in the existing C language source code foundation the skill. Introduced in compiles C55x in the series DSP assembly program the key technologies, such as in function call's parameter transmission, the instruction optimizes, flag bit establishment, great use and so ...

Short Content: Abstract: This article introduced briefly based on the IXP421 pronunciation gateway's system structure, as well as pronunciation DSP module principle of work. In system not special-purpose pronunciation DSP, but realizes by the IXP421 XSCALE nucleus. The system software, the application software and pronunciation DSP shares the CPU time. Pronunciation handling ability will receive the encoding method and the CPU load restriction, therefore, this article stated through the actual system's test result to Intel Corporation the performance index has carried on ...
