7.1.4.4 Software Development
Figure 7-4. Code Editor
Anchoring the tool is a modern, highly customizable user
interface. It includes project management and integrated editors
for C and assembler source code, as well the design entry tools.
Project build control leverages compiler technology from top
commercial vendors such as ARM^® Limited, Keil™, and
CodeSourcery (GNU). Free versions of Keil C51 and GNU C
Compiler (GCC) for ARM, with no restrictions on code size or end
product distribution, are included with the tool distribution.
Upgrading to more optimizing compilers is a snap with support
for the professional Keil C51 product and ARM RealView™
compiler.
7.1.4.5 Nonintrusive Debugging
Figure 7-5. PSoC Creator Debugger
With JTAG (4-wire) and SWD (2-wire) debug connectivity
available on all devices, the PSoC Creator debugger offers full
control over the target device with minimum intrusion.
Breakpoints and code execution commands are all readily
available from toolbar buttons and an impressive lineup of
windows—register, locals, watch, call stack, memory and
peripherals—make for an unparalleled level of visibility into the
system.
PSoC Creator contains all the tools necessary to complete a
design, and then to maintain and extend that design for years to
come. All steps of the design flow are carefully integrated and
optimized for ease-of-use and to maximize productivity.
7.2 Universal Digital Block
The UDB represents an evolutionary step to the next generation
of PSoC embedded digital peripheral functionality. The
architecture in first generation PSoC digital blocks provides
coarse programmability in which a few fixed functions with a
small number of options are available. The new UDB
architecture is the optimal balance between configuration
granularity and efficient implementation. A cornerstone of this
approach is to provide the ability to customize the devices digital
operation to match application requirements.
To achieve this, UDBs consist of a combination of uncommitted
logic (PLD), structured logic (Datapath), and a flexible routing
scheme to provide interconnect between these elements, I/O
connections, and other peripherals. UDB functionality ranges
from simple self contained functions that are implemented in one
UDB, or even a portion of a UDB (unused resources are
available for other functions), to more complex functions that
require multiple UDBs. Examples of basic functions are timers,
counters, CRC generators, PWMs, dead band generators, and
communications functions, such as UARTs, SPI, and I²C. Also,
the PLD blocks and connectivity provide full featured general
purpose programmable logic within the limits of the available
resources.
