ARCHITECTURAL OVERVIEW
The high performance of the PIC16C55X family can be
attributed to a number of architectural features
commonly found in RISC microprocessors. To begin
with, the PIC16C55X uses a Harvard architecture in
which program and data are accessed from separate
memories using separate busses. This improves
bandwidth over traditional von Neumann architecture
where program and data are fetched from the same
memory. Separating program and data memory further
allows instructions to be sized differently from 8-bit
wide data words. Instruction opcodes are 14-bit wide
making it possible to have all single word instructions.
A 14-bit wide program memory access bus fetches a
14-bit instruction in a single cycle. A two-stage pipeline
overlaps
fetch
and
execution
of
instructions.
Consequently, all instructions (35) execute in a single-
cycle (200 ns @ 20 MHz) except for program branches.
The table below lists the memory (EPROM and RAM).
The PIC16C554 addresses 512 x 14 on-chip program
memory. The PIC16C557 and PIC16C558 addresses
2 K x 14 program memory. All program memory is inter-
nal.
The PIC16C55X can directly or indirectly address its
register files or data memory. All special function
registers, including the program counter, are mapped
into the data memory. The PIC16C55X has an orthog-
onal (symmetrical) instruction set that makes it possible
to carry out any operation on any register using any
Addressing mode. This symmetrical nature and lack of
‘special optimal situations’ make programming with the
PIC16C55X simple yet efficient. In addition, the
learning curve is reduced significantly.
The PIC16C55X devices contain an 8-bit ALU and
working 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
otherwise mentioned, arithmetic operations are two's
complement in nature. In two-operand instructions,
typically
one
operand
is
the
working
register
(W register). The other operand is 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
SUBLW and SUBWF
instructions for examples.
A simplified block diagram is shown in Figure 3-1, with
a description of the device pins in Table 3-1.
