„ wide range of flexible programmable applications
– intelligent data pre-conditioning e.g. building up mean value of several
concurrently sampled ADC values
– DMA data transportation like queued memory or FIFO structures e.g. coming
from serial communication interfaces like CAN, SPI or ASC off-loads TriCore and
realizes partially peripheral functionality in SW
– complex state machines easily can be coded e.g. flywheel driver SW

Structure and Benefits
Two independent move engines for 8 *) channels each can have simultaneous R/W access
to SPB and RPB without interfering each other. By mapping simple data transportation
tasks to the DMA controller, the TriCore CPU and Peripheral Control Processor (PCP) are
significantly released and might focus on their application and low level driver tasks.
Infineon
Technologies AG
02.2005
„ flexible usage for single event or continuous transfer operation including programmable
data width for 8/16 or 32 bit memory transfer transactions covers a wide range of feasible
customer application requirements
„ flexible interrupt generation from up to 34 *) different interrupt sources (e.g. for data pattern
recognition) fulfills clear hierarchical separation of HW driven data transfers and needed SW
interaction
„ programmable request wiring matrix of 8 hardwired possible inputs for each DMA channel
supports maximum adaptation flexibility to the customer
„ combination of hardwired channel priority with programmable SW priority for each
individual DMA channel offers maximum adaptation to application demands
TC1796 Peripherals –
Memory Checker
Capabilities
Check dedicated memory portions (e.g. program
memory flash or program SRAM memory of the
PCP) in background for correctness
(e.g. to be able to determine code corruption)
Structure and Benefits
The memory checker has implemented a polynomial generator which equals to the
standard used within Ethernet:
G32 = x32 + x26 + x23 + x22 + x16 + x12 + x10 + x8 + x7 + x5 + x4 + x2 + x + 1
Any bus master (TriCore CPU, PCP or DMA controller) might serve the memory checker
located on the SMIF interface of the DMA module.
„ checking a memory portion is feasible by a sequential read of dedicated memory portion and a
sequential write to a single address of the memory checker located on the SMIF interface
„ simple compare function is needed to fell a decision whether calculated memory checker
result matches to the pre-calculated expected result stored somewhere in the FLASH area
Infineon
Technologies AG
02.2005
„ using a DMA channel offloads TriCore CPU and PCP and additionally offers the benefit of
only seen READ operations on the System Peripheral Bus (SPB) or the Remote Peripheral Bus
(RPB). The write operation to the memory checker by the move engine is hidden within the
DMA (routed to SMIF interface) and does not require any bandwidth of SPB or RPB

Capabilities
The GPTA offers very flexible filtering and high resolution signal acquisition, a digital PLL used
for the generation of a higher resolution of input signals and due to its universal cell structure all
kinds of enhanced counting, capture compare and PWM functionality.
Structure and Benefits (1/2)
perfect adaptation to target application by non-static modular cell approach compared
to timer implementations of the competition:
„ very flexible digital input filtering can be achieved by the usage of the implemented Filter
Prescaler Cells (FPC). Flexible strategies between delayed and immediate debounce filtering
are possible (e.g. for input filtering of the flywheel or the camshaft signals)
„ tracking of all kind of rotating shafts (e.g. within a gearbox system) including the encoding of
the signals for the forward and backward position can be easily achieved by usage of the
Phase Discrimination Logic (PDL) cells which supports the decoding of 2 and 3 sensor input
signals

Structure and Benefits (2/2)
perfect adaptation to target application by non-static modular cell approach compared
to timer implementations of the competition:
„ independent access to time and angle domain by two global timers (GT0/GT1)
with corresponding Global Timer Cell (GTC) array
- optimal support for capture/compare interaction corresponding to time or angle counters
(e.g. injection or ignition for gasoline engines)
„ all kinds of PWM generation are supported by the usage of the Local Timer Cell (LTC) array.
Hereby all kind of desirable scalability in terms of
- autonomous full coherent high speed PWM generation from 0-100% duty cycle with five
LTC cells driven completely in HW down to
- SW supported PWM generation from 10-90% duty cycle with minimum on one LTC cell
of used GPTA resources can be easily implemented
„ optimal application driven balance between precise HW driven event generation (e.g. HW
driven start of ignition on pre-calculated engine angle) and SW driven interrupt tasks
(e.g. reconfiguration of the compare value for next ignition start)

„ Peripheral Control Processor (PCP2) is an ideal counterpart for the SW handling of short
and real-time critical GPTA interrupt demands. PCP and GPTA may realize flywheel, ignition
and injection low level driver functionality without any TriCore interaction
„ In field test and repair feasible due to dynamic reconfigurable in/out multiplexer and array of
replaceable blocks
TC1796 Peripherals – ADC/Fast ADC
Aanalog to Digital Converters ADC and Fast ADC
Capabilities
AUDO-NG incorporates two different implementations for ADC peripherals using successive
approximation conversion principle:
- two ADC modules with programmable resolution 8/10/12 bit and conversion time of
1,25 µs @ 10bit
with a sophisticated feature set for autonomous analog/digital data acquisition
- one Fast ADC module with 10 bit resolution and a minimum conversion time of 280 ns resp.
(corresponding to 3,5 Msamples) including a data reduction filter with moving average
- auto-calibration mechanism build in at power up
FADC targeted application segments are knock detection and dynamic control of ignition
by ion current measurement
Structure and Benefits Fast ADC
unique solution for knock detection without external ASICs or dedicated DSP
„ reduced SW load for FIR-Filter by usage of integrated decimation comb filter
(e.g. data reduction by factor 6 from 1200 to 200 ksamples)
„ quick adaptation of the overall filter quality to the application demands by programmable
adaptation of data rate used for the FIR filter
Infineon

„ increase of ADC accuracy by data reduction filter and moving averaging filter
(e.g. from 10 bit to 11 bit by selected oversampling factor of 4)
TC1796 Peripherals – MLI
Multiprocessor Link Interface
Capabilities
AUDO-NG incorporates two MLI modules which are used for a serial high speed inter processor
connection to other AUDO-NG family members.
Structure and Benefits MLI
„ serial high speed interface up to fMLI/2 (i.e. 37,5 MBAUD for TC1796) which is used for interprocessor communication between the AUDO_NG family members and therefore offers the
possibility of scalable processing power within an application
„ parallel memory accesses to up to four memory windows automatically will be converted to serial
high speed MLI protocol and vice versa at the other MLI device
„ capability of posting up to four interrupts to the second processor on the other side by sending a
command frame
„ high efficient data transfer bandwidth supported (up to 35 MBaud) by special protocol for data,
address offset or data and address offset
„ for security reasons MLI interface is locked after HW reset and first has to be unlocked by the
device itself

TC1796 Peripherals – MSC
Micro Second Channel
Capabilities
purpose of the MSC module is to set a new open standard for the serial high speed communication
to power ASIC modules, like multi-switches (i.e. for ignition or injection drivers) including transfer of
command frames, data frames and asynchronous diagnosis feedback from the device
Structure and Benefits MSC
Design goals for the new approach has been:
„ parallel high speed PWM channels generated by the General Purpose Timer Array (GPTA) are
serialized via MSC module and transferred to the corresponding MSC module within the connected
power ASIC device without any additional SW load
„ maximum resolution for transferred PWM data is 500 kHz or 2µs period length
„ 2x2 signal wires Low-Voltage Differential Signals (LVDS) drivers implemented for high speed
downstream signals (CLK and Data) for lower EMI
„ asynchronous upstream channel implemented for diagnosis data for getting rid of SPI used
polling mechanism
„ 6 wires used to connect up to 32 high speed PWM channels instead of the standard SPI approach
with 36; saving of up to 30 package pins on the MC and power asic side offers ability of smaller
pin counts on packages for microcontroller and power asic and therefore saves system costs
„ scalable approach supported for the connection of up to four MSC power devices to one module
„ standard SPI protocol alternatively supported for high speed downstream channel

Summary – Peripheral Support
TriCore Architecture
combining three worlds of µProcessor, µController and
DSP results in scalable HW resources optimized for
embedded Powertrain applications
optimized Bus Architecture
Three layer SW concept simplifies clear hierarchical
separation of e.g. “Branding Application SW” based on the
IP of the OEM and standard Low Level Driver SW delivered

Enhanced Peripheral Modules helps to lower system
costs by:
• saving package pins of the µC through serialization
(e.g. µs-Bus for external Power ASSP)
• porting external ASIC function to AUDO-NG
(e.g. saving external Knock-ASIC by FADC usage)
• scalable system performance (e.g. connecting family
members of AUDO-NG through MLI bus)
