Hi, all, The following code snippet are for C64x touch assembly routine, which can be available in the TI document, spru656a. I don't know why we should choose "31" in the 4th line, || ADDAW .D2 B4, 31, B4 ; Round up # of iters Why not select "32"? Let's take a look at a example. If we have an array, short x[65], the length of which are 130 bytes. Assume that x[0] is located at 0x000...

Hello, I am new here. . first post. I have written code on a HCS12 uC (Dragon 12Plus Board) that meets the write wave form (HAS unused) in the HPI Ref. Guide. I verified this on a MSO2014; by verified I mean my HCNTL bits, HCS, and HSD1 bits are all jiving (it looks right) I am simulating HRDY by sending out a manual burst signal on a function generator. I am using a DSK6713, no daughter...

Dear everybody, I want to plot Eb/N0 vs BER bpsk demodulation in Matlab. I am using BPSK modulated signal @ carrier frequencey 8KHz, data rate 1KHz. Sampling rate is set to 96000Hz. I have tried to use 'awgn function' for adding noise. This signal accepts Signal to noise ratio (SNR)in parameters. In order to convert into Eb/N0 for BPSK signal. I have used following relat...

Hello I'm having trouble trying to run VCP2 on Big Endian Mode in a 6474 EVM. I'm working on an example project, which is working fine in Little Endian mode, the project gets data, convolutional encodes, expands bits to bytes, calculates branch metrics and setup VCP2. But I couldn't manage to get right results in Big Endian mode. Can anyone help me with this issue? Alphan. ___________________...

Hi I need to do some processing where the processed lines are far away one to another. For this purpose i am using 2D EDMA3 (2D to 1D) transfer of these line from DDR2 external memory to DSP;s internal memory. The problem come out when the byte offset between the lines is more then 32K and i can not perform 2D transfer because the the SRCBIDX register which indicating the byte offset...
