hi every one, I am a design engineer and doing voice compression in ADSP 218x series.This is basically a 16 bit processor. Actually i am porting C-code in Assembly and I am using its IDE ( Analog Devices Visual DSP ++). Now i am facing a problem in handling 40 bit arithmatic. complete description of my quary is below. " A 40 bit variable ' L40_sum ' , this varia

Hello, I am doing IDMA reading and writting on an ADSP-2189N, revision 3.2 When writting, which I use for boot up from a host PC via a microcontroller, everything goes fine, which I can verify by means of the 218x-EzICE. But when reading the con

Hi, First of all I am sorry if you are receiving multiple copies of this mail. I am trying to program and communicate with CODEC AD73311AR on SPORT0. I have programmed the CODEC to work at 1.024MHz SClock and 32KHZ sampling frequency. I am using I2 and I3 for initializing SPORT0. I am attaching the code for CODEC and SPORTs initialization function. It is clear from the code that I have buffers...

I need to decode multiple MPEG layer IIc audio streams in one or more DSPs. I'm considering either the fixed point 2189 or the sharc 21065, both of which are listed as having support for MPEG audio decoding buried in the analog devices web pages. does anyone have any recommendations

Hello everyone, hope everyone is doing fine. I'm a newbie in ADSP 218x (2181). I have strong micro-controller background .... I have some problems in BDMA, Please be patient to answer my simplest questions. question about BDMA are as follows: 1) Is BDMA used to download the program (that we burn in flash memory) from any flash into the DSP program memory and then ex

I have not used the emulated UART routine with the 219x. I talked with another engineer who is versed on the 218x and he told me pretty much that it's a bit banged UART setup. The RX'ED start bit is picked up with a input flag pin and timer is setup up to interrupt the processor at 3 times the clock rate. On each timer interrupt the dsp samples the UART in

I am familiar with the 218x where imask is pushed into the status stack upon interrupt. From what I read, the 219x/2199x does not. It somehow prohibits interrupts from being serviced when in another ISR (assuming nesting mode is not enabled). What is the exact mec
