Dear Sir
I am using SHARC 21065L Processor, and VDSP4.0++ Simulator. My Querry is How to
Declare a Circular Buffer of Array Size 25?, And How to call the Buffer.

With the circular buffer registers, like so:
In the data section, declare the data array:
"
.VAR circular_buffer_data[25];
"
In the code section, initialize the circular buffer registers:
"
b0 = circular_buffer_data; // base address of circular buffer
l0 = length(circular_buffer_data); // length register
"
Now you can use i0 as a circular buffer index register. For example,
reading and writing can be done like this:
"
f0=dm(i0,0); // read output from circular buffer into f0
dm(i0,1) // store input f4 into circular buffer
"
This would implement a standard delay functionality.
