Communication Processor Module
The first half-word is composed of the following bits:
S—STOP
Bits 1, 9, and 10—Reserved
These bits are reserved and must be set to 0.
W—Wrap (Final Function Descriptor in Table)
I—Interrupt
Z— Complex Output
IALL— Auto-Increment X For All Iterations
INDEX— Auto-Increment Index
PC— Preset Coefficients Pointer
OPCODE—Function Operation Code
This field specifies the function to be executed. Table 16-6 contains the value for this field.
0 = Do not stop after executing this function descriptor.
1 = Stop after executing this function descriptor.
0 = This is not the last function descriptor in the function descriptor table.
1 = This is the last function descriptor in the function descriptor table. After this buffer
0 = No interrupt is generated after this function is processed.
1 = A maskable interrupt is generated after this function is processed.
0 = Only the real component of the result is written to the output buffer.
1 = The real and imaginary parts of the result are written to the output buffer.
0 = The X (input) data pointer is incremented (Modulo M+1) by the number of samples
1 = The X data pointer is incremented (Modulo M+1) by the number of samples
00 = The X (input) pointer is not incremented.
01 = The X (input) pointer is incremented by one sample.
10 = The X (input) pointer is incremented by two samples.
11 = The X (input) pointer is incremented by three samples.
0 = The coefficients pointer is not preset after each iteration.
1 = The coefficients pointer is preset after each iteration to the CBASE pointer.
has been used, the CPM processes the first function descriptor that the FDBASE
index pointer points to in the table. The number of function descriptors in this table
are programmable and determined only by the W bit and overall space constraints
of the memory.
specified in the INDEX field after the last iteration.
specified in the INDEX field after each iteration.
