PIC16F5X
2.0
ARCHITECTURAL OVERVIEW
The high performance of the PIC16F5X family can be
attributed to a number of architectural features
commonly found in RISC microprocessors. To begin
with, the PIC16F5X uses a Harvard architecture in
which program and data are accessed on separate
buses. This improves bandwidth over traditional von
Neumann architecture where program and data are
fetched on the same bus. Separating program and data
memory further allows instructions to be sized differ-
ently than the 8-bit wide data word. Instruction opcodes
are 12-bits wide, making it possible to have all single-
word instructions. A 12-bit wide program memory
access bus fetches a 12-bit instruction in a single cycle.
A two-stage pipeline overlaps fetch and execution of
instructions. Consequently, all instructions (33) execute
in a single cycle except for program branches.
The
PIC16F54
addresses
512 x 12
of
program
memory, the PIC16F57 and PIC16F59 addresses
2048 x 12 of program memory. All program memory is
internal.
The PIC16F5X can directly or indirectly address its
register files and data memory. All Special Function
Registers (SFR), including the program counter, are
mapped in the data memory. The PIC16F5X has a
highly orthogonal (symmetrical) instruction set that
makes it possible to carry out any operation on any reg-
ister using any Addressing mode. This symmetrical
nature and lack of ‘special optimal situations’ make pro-
gramming with the PIC16F5X simple, yet efficient. In
addition, the learning curve is reduced significantly.
The PIC16F5X device contains an 8-bit ALU and work-
ing register. The ALU is a general purpose arithmetic
unit. It performs arithmetic and Boolean functions
between data in the working register and any register
file.
The ALU is 8-bits wide and capable of addition,
subtraction, shift and logical operations. Unless other-
wise mentioned, arithmetic operations are two's
complement in nature. In two-operand instructions,
typically one operand is the W (working) register. The
other operand is either a file register or an immediate
constant. In single operand instructions, the operand is
either the W register or a file register.
The W register is an 8-bit working register used for ALU
operations. It is not an addressable register.
Depending on the instruction executed, the ALU may
affect the values of the Carry (C), Digit Carry (DC) and
Zero (Z) bits in the STATUS Register. The C and DC
bits operate as a borrow and digit borrow out bit,
respectively, in subtraction. See the SUBWF and ADDWF
instructions for examples.
A simplified block diagram is shown in Figure 2-1 with
the corresponding device pins described in Table 2-1
(for PIC16F54), Table 2-2 (for PIC16F57) and
Table 2-3 (for PIC16F59).
