Difference between ADSP-SC587BBCZ-4B and ADSP-SC589BBCZ-5B

Hi,

There is a temperature difference between these parts.
ADSP-SC587BBCZ-4B - –40°C to +85°C
ADSP-SC589BBCZ-5B - –40°C to +80°C

Please refer the ordering guide in page:173 of SC58x Datasheet for more information.

Dear Divya, 

Thank you for reply.

I want to know about "Processor Instruction Rate".

Thank you.

Best Regards,

Hi Inho Jeon,

Maximum Processor Instruction rate:
ADSP-SC587BBCZ-4B -  450MHz
ADSP-SC589BBCZ-5B -  500MHz

 What is "Maximum Processor Instruction rate"?

Hi Inho John,

The maximum instruction rate of the processor means the maximum number of instructions executed in a second by processor.

Dear Divya,

Which processor are you talking about? ARM Core or DSP Core or both Core? 

And, I want to know 'maximum instruction rate' convert to MIPS(Million Instructions Per Second).

Hi Inhojeon,


Instruction rate is applicable of both cores.

The MIPS can be calculated by below equation.
MIPS = (Processor clock speed * Num Instructions executed per cycle)/(10^6).

Where, the 'Num Instructions executed per cycle' can be obtained using "Performance Monitor Unit (PMU)" which calculate cycle counts for the application running in Cortex A5 core.

Also, kindly refer the below ezone thread.

Dear Divya, 

I have attached the file.

It's a malfunction of my audio device.

It works fine at first. Music that plays normally.

However, as I attached the file, after 3-4 hours, the beep sounds.

Please ask which part is the problem.
