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, 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...

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.

One SHARC is always the bus master, and will hold BR until another asserts its BR. If the original bus master does not need the bus at that point, it will deassert BR, granting the transfer of ownership. The new bus master will then hold the bus until another SHARC asks for it.
