11.11.6 BCOPY, DMA Operation
See also Page 11-127 for TC1796 specific details of the BCOPY instruction.
BCOPY Syntax BCOPY DST+-, SRC+-, CNC, CNT0
Description Allows the PCP to perform DMA type transfers using FPI
block transfers.
Moves the contents of FPI Bus source location to FPI Bus
destination location. Source location is pointed to by the
contents of register R4; destination location is pointed to by
the contents of register R5. Options (see also Table 11-13 at
Page 11-74) are:
Source pointer (SRC+-): Increment, decrement or
unchanged
Destination pointer (SRC+-): Increment, decrement or
unchanged
Counter control (CNC): see Table 11-13
Block size value (CNT0): see Table 11-13
Operation temp = zero_ext(FPI[R[4]]); value loaded and extended
depending on SIZE
FPI(R[5]) = temp
R4 = R4 +/- n; n depending on SRC+- and CNT0
R5 = R5 +/- n; n depending on DST+- and CNT0
For counter operation see Figure 11-14 at Page 11-78 and
Table 11-13 at Page 11-74.
