PROGRAM DATA TABLE ACCESS (MSB)
3.1.2
DATA ACCESS FROM PROGRAM
MEMORY USING PROGRAM SPACE
VISIBILITY
The upper 32 Kbytes of data space may optionally be
mapped into any 16K word program space page. This
provides transparent access of stored constant data
from X data space without the need to use special
instructions (i.e., TBLRDL/H, TBLWTL/H instructions).
Program space access through the data space occurs
if the MSb of the data space, EA, is set and program
space visibility is enabled by setting the PSV bit in the
Core Control register (CORCON). The functions of
CORCON
are
discussed
in
Section 2.4
“DSP
Engine”.
Data accesses to this area add an additional cycle to
the instruction being executed, since two program
memory fetches are required.
Note that the upper half of addressable data space is
always part of the X data space. Therefore, when a
DSP operation uses program space mapping to access
this memory region, Y data space should typically con-
tain state (variable) data for DSP operations, whereas
X data space should typically contain coefficient
(constant) data.
Although each data space address, 0x8000 and higher,
maps directly into a corresponding program memory
address (see Figure 3-6), only the lower 16 bits of the
24-bit program word are used to contain the data. The
upper 8 bits should be programmed to force an illegal
instruction to maintain machine robustness. Refer to
the “16-bit MCU and DSC Programmer’s Reference
Manual” (DS70157) for details on instruction encoding.
Note that by incrementing the PC by 2 for each
program memory word, the 15 LSbs of data space
addresses directly map to the 15 LSbs in the corre-
sponding program space addresses. The remaining
bits are provided by the Program Space Visibility Page
register, PSVPAG<7:0>, as shown in Figure 3-6.
For instructions that use PSV which are executed
outside a REPEAT loop:
The following instructions require one instruction
cycle in addition to the specified execution time:
- MAC class of instructions with data operand
prefetch
- MOV instructions
- MOV.D instructions
All other instructions require two instruction cycles
in addition to the specified execution time of the
instruction.
For instructions that use PSV which are executed
inside a REPEAT loop:
The following instances require two instruction
cycles in addition to the specified execution time
of the instruction:
- Execution in the first iteration
- Execution in the last iteration
- Execution prior to exiting the loop due to an
interrupt
- Execution upon re-entering the loop after an
interrupt is serviced
Any other iteration of the REPEAT loop allows the
instruction accessing data, using PSV, to execute
in a single cycle.
