The dsPIC33FJ32MC202/204 and dsPIC33FJ16MC304
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 flow, the double-word move (MOV.D) instruction
and the table instructions. Overhead-free program loop
constructs are supported using the DO and REPEAT
instructions, both of which are interruptible at any point.
The dsPIC33FJ32MC202/204 and dsPIC33FJ16MC304
devices have sixteen, 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 working register (W15) operates as a software Stack
Pointer (SP) for interrupts and calls.
There
dsPIC33FJ32MC202/204 and dsPIC33FJ16MC304
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,
dsPIC33FJ16MC304 is capable of executing a data (or
program data) memory read, a working register (data)
read, a data memory write and a program (instruction)
memory read per instruction cycle. As a result, three
parameter instructions can be supported, allowing
A + B = C operations to be executed in a single cycle.

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 register (PSVPAG). The
program-to-data-space mapping feature lets any
instruction access program space as if it were data
space.

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.
