Other Parts Discussed in Thread: PCM5242
你好,
PCM5242 采样率在96K/192K的时候,不能调节EQ (HYBRID FLOW 1-7)都不能使用?怎么办?
芯片设计就是这样吗?只能48KHZ的时候才能调节内部的EQ 和DRC参数?
您好
The PCM5242 features a programmable miniDSP core that offers Hybrid-Flows which are a RAM/ROM
combination of code. Common functions are embedded in ROM, and custom RAM flows, created by TI can be
run on the miniDSP core. The algorithms for the miniDSP must be loaded into the device after power up. The
miniDSP can run up to 1024 instructions on every audio sample at a 48kHz sample rate. Development is done
using Purepath Console software.
根据datasheet描述 miniDSP core处理能力能保证48Khz的处理能力
NOTE At higher sampling frequencies, fewer instruction cycles are available. (For example, 512 instructions can be done in a 96kHz frame.)
在高频处理能力有限。
