3.1
The
dsPIC33FJ64MCX02/X04
dsPIC33FJ128MCX02/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 main-
tain throughput and provides predictable execution. All
instructions execute in a single cycle, with the excep-
tion 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 time.
The
dsPIC33FJ64MCX02/X04
dsPIC33FJ128MCX02/X04 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.

dsPIC33FJ32MC302/304,
and dsPIC33FJ128MCX02/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
dsPIC33FJ64MCX02/X04
dsPIC33FJ128MCX02/X04 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.
A block diagram of the CPU is shown in Figure 3-1, and
the
dsPIC33FJ32MC302/304,
and dsPIC33FJ128MCX02/X04 is shown in Figure 3-2.
3.2
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.
