3.1
The dsPIC33FJ32GP302/304, dsPIC33FJ64GPX02/
X04, and dsPIC33FJ128GPX02/X04 CPU module has
a 16-bit (data) modified Harvard architecture with an
enhanced instruction set, including significant support
for DSP. The CPU has a 24-bit instruction word with a
variable length opcode field. The Program Counter
(PC) is 23 bits wide and addresses up to 4M x 24 bits
of user program memory space. The actual amount of
program memory implemented varies by device. A
single-cycle instruction prefetch mechanism is used to
help maintain throughput and provides predictable
execution. All instructions execute in a single cycle,
with the exception of instructions that change the
program
instruction and the table instructions. Overhead-free
program loop constructs are supported using the DO
and
interruptible at any time.
The dsPIC33FJ32GP302/304, dsPIC33FJ64GPX02/
X04, and dsPIC33FJ128GPX02/X04 devices have six-
teen, 16-bit working registers in the programmer’s
model. Each of the working registers can serve as a
data, address or address offset register. The 16th work-
ing register (W15) operates as a software Stack Pointer
(SP) for interrupts and calls.
There
dsPIC33FJ32GP302/304, dsPIC33FJ64GPX02/X04,
and dsPIC33FJ128GPX02/X04 devices: MCU and
DSP. These two instruction classes are seamlessly
integrated into a single CPU. The instruction set
includes many addressing modes and is designed for
optimum C compiler efficiency. For most instructions,
the dsPIC33FJ32GP302/304, dsPIC33FJ64GPX02/
X04, and dsPIC33FJ128GPX02/X04 is capable of exe-
cuting a data (or program data) memory read, a work-
ing register (data) read, a data memory write and a
program (instruction) memory read per instruction

The data space can be addressed as 32K words or
64 Kbytes and is split into two blocks, referred to as X
and Y data memory. Each memory block has its own
independent Address Generation Unit (AGU). The
MCU class of instructions operates solely through the
X memory AGU, which accesses the entire memory
map as one linear data space. Certain DSP instructions
operate through the X and Y AGUs to support dual
operand reads, which splits the data address space
into two parts. The X and Y data space boundary is
device-specific.
Overhead-free circular buffers (Modulo Addressing
mode) are supported in both X and Y address spaces.
The Modulo Addressing removes the software
boundary checking overhead for DSP algorithms.
Furthermore, the X AGU circular addressing can be
used with any of the MCU class of instructions. The X
AGU also supports Bit-Reversed Addressing to greatly
simplify input or output data reordering for radix-2 FFT
algorithms.
The upper 32 Kbytes of the data space memory map
can optionally be mapped into program space at any
16K program word boundary defined by the 8-bit
Program Space Visibility Page (PSVPAG) register. The
program-to-data-space mapping feature lets any
instruction access program space as if it were data
space.
3.3
The DSP engine features a high-speed 17-bit by 17-bit
multiplier, a 40-bit ALU, two 40-bit saturating
accumulators and a 40-bit bidirectional barrel shifter.
The barrel shifter is capable of shifting a 40-bit value up
to 16 bits right or left, in a single cycle. The DSP
instructions
instructions and have been designed for optimal real-
time performance. The MAC instruction and other
associated instructions can concurrently fetch two data
operands from memory while multiplying two W
registers and accumulating and optionally saturating
the result in the same cycle. This instruction
functionality requires that the RAM data space be split
for these instructions and linear for all others. Data
space partitioning is achieved in a transparent and
flexible manner through dedicating certain working
registers to each address space.
