Hello everybody, I have set up two Sharc 21065L in a multiprocessor enviroment. If they get their code from the external SDRAM, there is a problem with the switching of bus mastership. One DSP is retaining mastership for over 15 microseconds. But I set up the processors t

Hi Jackie, we use host booted SHARC systems for our products. What we do is forget about loader programs (these are for systems with no host in my opinion), but use the host to download the DSP code from a FLASH memory to the SHARC via DMA, and then use the e

Hi All, We are developing a Tiger SHARC based board, the design of which is very similar to the AD-TS101S EZKIT LITE. The core voltage(1.2V), IO voltage (3.3V) and clock (83.3MHz) seem to be OK. The Tiger SHARC is also recognized by the AD JTAG Emulator, and I am

Hi, I have been wondering if is it possible to do SHARC and 218X-219x development on the same computer, I mean, VisualDSP++ 1.0 SP1 and VisualDSP++ 2.0 for 21xx on the same hard disk? Any pointer on how to do it is ver, very welcomed. Best regards,

Hi, I have to call a C function from a SHARC assembly routine. I have read about assembly and C interfacing in C/C++ Compiler and Library manual for SHARC where I came across the ccall macro. Using this macro I can pass parameters to the C function through registers r4 and r8. I can also see that the result appears in registers r0. However, the program does not return from the C fun...

Hi, I've been trying to use a SHARC (21065 and 21262) SPORT as a SPI slave. I have observed that when I receive data, it is right shifted by a couple of bits (usually 3, but not always). If I send a "dummy byte", ie a byte in which the Sharc is not selected (selectio

I am evaluating the Sharc 21065L. I am a private user doing it just for fun and so, the VisualDSP++ - Environment (with C-Compiler) is not affordable for me. Is there a free C-Compiler or Developing Environment for Sharc 21065L available? (For Windows)

Hi, I'm new to DSP programming - though I have experience in assembly programming of micro-controllers. I have a Analog Devices AD-21479 SHARC EZ-KIT, and I'm trying to program an audio pass-thru using the boards SPDIF In and OUT connectors. I'm using the on-chip SPDIF receiver to take my incoming SPDIF input stream from the SPDIF input socket, and feeding this on to the SPORT 0 serial in. Simi...

Dear fellow Sharc programmers, The Signal Routing Unit is a great feature but the documentation is unclear. Beware that when using the Group E Misc registers, you can only use one signal from each group of 5 bits. For example, in the SRU_EXT_MISCA register, you cannot use the MISCA0_I input and the FLAG13_I input simultaneously or they will conflict! Gene Goff Ashly Audio, Inc.
