I don't know where this linking error come from:
bfin-elf-gcc -g -mcpu=bf561 -mmulticore -mcoreb -mlong-calls -Wall -save-temps …
I´m using the High speed ADC "AD9272BSVZ-40", i want to know if it´s possible to use a clock oscillator of 50 MHz , or the maximum frequency of the clock oscillator has to be 40 MHz.
How can I use Blackfin 40 bits accumulator.
Can I use it in C, or must I use assembler.
We are looking for amplifiers in 1-20 MHz band to output 10 W, we have found 2 such amplifiers in a close range– HMC8500 and HMC1099; they both operate in the 0.01-1.1 GHz range. We were wondering if the amplifier can operate below 10 MHz…
We check power consumption of AD9237-40 both power scaling enable and disable .Datasheet figure 43 and 44 describle only power consumption by 10MSPS at power scaling disable and enable.Please let me knoe about power consumption when we use AD9237…
I try to find a good way to save and restore 40-Bit register values (floating point in f0-f15) during an interrupt service routine.
My audio calculations are done in 40-Bit floating point, my SPI communicates with a microcontroller.
The SPI end…
VisualDSP++ 5.0 C/C++ Compiler Manual for SHARC Processors describe why 40 bit operation is absent.
I want to debate about this.
As datasheet is written:
Where possible, the compiler will attempt to perform constant folding (the simplification…
I am working on the ADSP21489 EZ-Kit.
The datasheet says that this processor is capable of working not only with 32-bit floating point formats but also with 40-bit as well.
I found the following discussion on a forum, but this discussion was quite…
I encountered some issues about AD9212-40, could you please help check them
1、when CLK doesn't connect the common-mode voltage, what is voltage for pin9（clk-） and pin10（clk+）, should it be 1.6V or 1.25V.
2、 how to start the test…
Please let me know about the threshold of mode pin in AD9237-40.
Datasheet P.20 describes below but does not describe threhold.
Mode2 ; Span ; Power scaling
AVDD ; 1; Disabled
2/3 AVDD ; 1; Enabled
1/3 AVDD ; 2 ;Enabled
AGND ; 2 ;Disable…
