2.0
This chapter summarizes the CPU and peripheral
functions of the dsPIC30F6010A/6015.
2.1
The core has a 24-bit instruction word. The Program
Counter (PC) is 23 bits wide with the Least Significant
bit (LSb) always clear (see Section 3.1 “Program
Address Space”), and the Most Significant bit (MSb)
is ignored during normal program execution, except for
certain specialized instructions. Thus, the PC can
address up to 4M instruction words of user program
space. An instruction prefetch mechanism is used to
help maintain throughput. Program loop constructs,
free from loop count management overhead, are
supported using the DO and REPEAT instructions, both
of which are interruptible at any point.
The working register array consists of 16x16-bit
registers, each of which can act as data, address or
offset registers. One working register (W15) operates
as a Software Stack Pointer for interrupts and calls.
The data space is 64 Kbytes (32K words) and is split into
two blocks, referred to as X and Y data memory. Each
block has its own independent Address Generation Unit
(AGU). Most instructions operate solely through the X
memory AGU, which provides the appearance of a
single unified data space. The Multiply-Accumulate
(MAC) class of dual source DSP instructions operate
through both the X and Y AGUs, splitting the data
address space into two parts (see Section 3.2 “Data
Address Space”). The X and Y data space boundary is
device-specific and cannot be altered by the user. Each
data word consists of 2 bytes, and most instructions can
address data either as words or bytes.
There are two methods of accessing data stored in
program memory:
• The upper 32 Kbytes of data space memory can be

mapped into the lower half (user space) of program
space at any 16K program word boundary, defined by
the 8-bit Program Space Visibility Page (PSVPAG)
register. This lets any instruction access program
space as if it were data space, with a limitation that the
access requires an additional cycle. Moreover, only
the lower 16 bits of each instruction word can be
accessed using this method.
CPU ARCHITECTURE
OVERVIEW
Core Overview
This data sheet summarizes features of
this group of dsPIC30F devices and is not
intended to be a complete reference
source. For more information on the
peripherals, register descriptions and
general device functionality, refer to the
“dsPIC30F Family Reference Manual”
(DS70046). For more information on the
device instruction set and programming,
refer to the “dsPIC30F/33F Programmers
Reference Manual” (DS70157).
dsPIC30F6010A/6015
• Linear indirect access of 32K word pages within
Overhead-free circular buffers (Modulo Addressing) are
supported in both X and Y address spaces. This is
primarily intended to remove the loop overhead for DSP
algorithms.
The X AGU also supports Bit-Reversed Addressing on
destination Effective Addresses, to greatly simplify input
or output data reordering for radix-2 FFT algorithms.
Refer to Section 4.0 “Address Generator Units” for
details on Modulo and Bit-Reversed Addressing.
The core supports Inherent (no operand), Relative,
Literal, Memory Direct, Register Direct, Register
Indirect, Register Offset and Literal Offset Addressing
modes. Instructions are associated with predefined
addressing modes, depending upon their functional
requirements.
For most instructions, the core is capable of executing
a data (or program data) memory read, a working reg-
ister (data) read, a data memory write and a program
(instruction) memory read per instruction cycle. As a
result, 3-operand instructions are supported, allowing
C = A + B operations to be executed in a single cycle.
A DSP engine has been included to significantly
enhance the core arithmetic capability and throughput.
It 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. Data in the accumulator
or any working register can be shifted up to 16 bits right
or 16 bits left in a single cycle. The DSP instructions
operate seamlessly with all other instructions and have
been designed for optimal real-time performance. The
MAC class of instructions can concurrently fetch two data
operands from memory, while multiplying two W
registers. To enable this concurrent fetching of data
operands, the data space has been split for these
instructions and linear for all others. This has been
achieved in a transparent and flexible manner, by
dedicating certain working registers to each address
space for the MAC class of instructions.
The core does not support a multi-stage instruction
pipeline. However, a single stage instruction prefetch
mechanism is used, which accesses and partially
decodes instructions a cycle ahead of execution, in order
to maximize available execution time. Most instructions
execute in a single cycle, with certain exceptions.
The core features a vectored exception processing
structure for traps and interrupts, with 62 independent
vectors. The exceptions consist of up to 8 traps (of which
4 are reserved) and 54 interrupts. Each interrupt is
prioritized based on a user-assigned priority between 1
and 7 (1 being the lowest priority and 7 being the highest)
in conjunction with a predetermined ‘natural order’.
Traps have fixed priorities, ranging from 8 to 15.
program space is also possible using any working
register, via table read and write instructions. Table
read and write instructions can be used to access
all 24 bits of an instruction word.
