Memory

Table 56 lists the memory requirements for the lib_voice DSP components. The estimates are provided as a guideline to help audio pipeline developers assess the memory cost of including a component in the pipeline.

Note

The IC memory usage includes VNR memory usage as well, since VNR processing is part of IC. Stand-alone VNR memory usage is also computed, as shown in the VNR row of the table.

Table 56 Memory usage (in bytes)

Component	Memory use (bytes)
ADEC	8840
AEC_ALT_ARCH	240400
AEC_STD_ARCH	277824
AGC	9896
IC	136344
NS	35664
VNR	62936

CPU

Table 57 lists the approximate CPU requirements in MIPS for the lib_voice DSP components. The MIPS values are computed as the worst-case processor cycles consumed by the component’s process_frame function. All CPU estimates are based on the default configuration for each feature. Alternate configurations may require more or less MIPS.

These estimates are provided as a guideline to help audio pipeline developers assess the CPU cost of including a component in the pipeline.

Note

The IC MIPS numbers include VNR processing that is part of IC. Stand-alone VNR processing numbers are also computed, as shown in the VNR row of the table.
