Instruction Definition
It seems the ADAU1701 can perform 1024 instructions at a 48KHz sample rate. I have looked at the software description for Sigma Studio without spending a long to looking. Can anyone tell me what an in

process structure in 1787 fast dsp FDSP
What is the process structure, with respect to number of bits in internal datapaths and memory and accumulator, used by the 1787 FDSP when executing a series of consecutive biquads? I imagine it is si

1787 FDSP number of instructions
What controls the number of instructions available per frame in the 1787 FDSP core? Is the number always 64, or will it sometimes be less than that? The datasheet says "The core is controlled with a 2

ADAU1701: How many instructions?
Hello, It's well known that some of the ADAU1701's 1024 instructions (at 48K sample rate) are needed for what's generally described as "overhead." Is there a better-defined answer for exactly how many

ADAU1701 Instruction Usage Table
Several designers have recently asked about how to estimate instruction usage by various algorithms on the ADAU1701, since its compiler does not itemize instruction usage by individual blocks. The att

1701 mclk vs max instructions
For the ADAU1701, if I change the MCLK from 12.288MHz to 24.576MHz and I have a sample rate of 192kHz, does the maximum number of instructions increase from 256 to 512 instructions maximum? Audio Sign
