A

Real Time Operating System:
Is an operating system (OS) intended to serve real-time applications that process data as it comes in, typically without buffering delays. Processing time requirements (including any OS delay) are measured in tenths of seconds or shorter increments of time. They either are event driven or time sharing. Event driven systems switch between tasks based on their priorities while time sharing systems switch the task based on clock interrupts.

FPGA

A

Field Programmable Gate Array
Is an integrated circuit designed to be configured by a customer or a designer after manufacturing - hence “field programmable”. The FPGA configuration is generally specified using a hardware description language (HDL), similar to that used for an applications-specific integrated circuit (ASIC).
FPGAs contain an array of programmable logic blocks, and a hierarchy of reconfigurable interconnects that allow the blocks to be “wired together”, like many logic gates that can be inter-wired in different configurations. Logic blocks can be configured to perform complex combinational functions, or merely simple logic gates like AND and XOR. In most FPGAs, logic blocks also include memory elements, which may be simple flip-flops or more complete blocks of memory.

ISO 11898

A

CAN (Controller Area Network)
In 1993, the International Organisation for Standardization (ISO) released the CAN standard ISO 11898.
A controller area network (CAN bus) is a robust vehicle bus standard designed to allow micro-controllers and devices to communicate with each other in applications without a host computer. It is a message-based protocol, designed originally for multiplex electrical wiring within automobiles to save on copper, but is also used in many other contexts.

80
Q

CRC

A

Cyclic Redundancy Check:
This protects the useful data in a CAN data transmission by appending a checksum to the useful data, which is evaluated by the receiver by applying the CRC algorithm.

81
Q

CSMA/CA Method

A

Carrier Sense Multiple Access/Collision Avoidance:
Ensures that CAN nodes wishing to send do not access the CAN bus until it is available. It also ensures that the CAN node with the highest priority data frame prevails.

82
Q

Bit Stuffing (CAN)

86
Q

NRE

A

Non Recurring Engineering:
Refers to the one-time cost to research, design, develop and test a new product or product enhancement.
When budgeting for a new product, NRE must be considered to analyse if a new product will be profitable.
Even though a company will pay for NRE on a project only once, NRE costs can be prohibitively high and the product will need to sell well enough to produce a return on the initial investment. NRE is unlike production costs, which must be paid constantly to maintain production of a product. Rather it is a form of fixed cost in economics terms. Once a system is designed, any number of units can be manufactured without increasing NRE cost.

87
Q

QoS

A

Quality of Service

88
Q

ROM

A

Rough Order of Magnitude

89
Q

MTTF

A

MTTF
Mean Time to Failure or θ is another standard industry value which provides the average time to failure of Non-repairable items such as light bulbs and diodes or unserviceable systems such as satellites or other unmanned space craft. For items with long life expectancies, it is often more useful to report MTTF in years than hours.

90
Q

MTBF

A

MTBF
Mean Time Between Failures is used to describe Repairable Items such as compressors and aircraft. MTBF uses MTTF as one factor and Mean Time to Repair (MTTR) as the other to capture the complete break-down and repair cycle. The primary purpose of MTBF is to identify appropriate preventive maintenance schedules to avoid, perhaps indefinitely, catastrophic failures due to predictable piece part wear-out. As a rule of thumb, component reliability centers around MTTF since most components cannot be repaired.

91
Q

ISO 15504

A

SPICE / ASPICE
Automotive - Software Process Improvement and Capability Determination is an international standard of ISO used to carry out assessments of company processes relating to the development of software.
The core elements of this norm:
The improvement of processes within the organisation (i.e. the transformation of input products to output products)
and
The determination of the process capability

92
Q

ASIC

A

ASIC
Commonly used in automotive computers to control the functions of the vehicle, Application-Specific Integrated Circuits are chips designed for a particular applications (as opposed to the integrated circuits that control functions such as RAM in a PC). ASICs are built by connecting existing circuit building blocks in new ways. Since the building blocks already exist in a library, it is much easier to produce a new ASIC than to design a new chip from scratch.

93
Q

PCB

A

PCB
A Printed Circuit Board mechanically supports and electrically connects electronic components or electrical components using conductive tracks, pads and other features etched from one or more sheet layers of copper laminated onto and/or between sheet layers of a non-conductive substrate. Components are generally soldered onto the PCB to both electrically connect and mechanically fasten them to it.

94
Q

ICT (Testing)

A

ICT (Testing)
In-Circuit Test is an example of white box testing where an electrical probe tests a populated printed circuit board (PCB), checking for shorts, opens, resistance, capacitance, and other basic quantities which will show whether the assembly was correctly fabricated.

95
Q

EOL (Testing)

A

EOL (Testing)
End-of-Line testers are responsible for testing the overall functionality of the product during the manufacturing process. Under the hard conditions of the manufacturing environment, test systems must simulate all the relevant conditions, whilst measuring the response of the equipment being tested.

96
Q

CAN-FD

A

CAN-FD
Denotes CAN with Flexible Data-Rate, which is an extension of the original CAN bus protocol. Developed in 2011 and released in 2012 by Bosch, it was originally created in response to the requests of automakers for more accurate, “real-time” data. Just like with classic CAN, this protocol is designed to record and transmit data, including errors, between devises and microcontrollers without the use of a central, “host” computer.
CAN FD is primarily designed to meet the needs of automakers, however, the pervasiveness of classic CAN indicates the inclusion of this improved protocol across a variety of applications, including defense, industrial automation, autonomous devices, underwater vehicles and medical equipment.

97
Q

SiP

A

SiP
System In Package or system-in-a-package is a number of integrated circuits enclosed in a single module (package). The SiP performs all or most of the functions of an electronic system, and is typically used inside a mobile phone, digital music player, etc. Dies containing integrated circuits may be stacked vertically on a substrate. They are internally connected by fine wires that are bonded to the package. Alternatively, with a flip chip technology, solder bumps are used to join stacked chips together.
SiP technology is primarily being driven by market trends in wearables, mobile devices and IoT. As the IoT becomes more of a reality and less of a vision, there is innovation going on at the system on a chip and SiP level so that MEMS sensors can be integrated on a separate die and control the connectivity.

98
Q

EEPROM

A

EEPROM
Stands for Electrically Erasable Programmable Read-Only Memory and is a type of non-volatile memory used in computers and other electronic devices to store relatively small amounts of data but allowing individual bytes to be erased and reprogrammed.
EEPROMs are organized as arrays of floating-gate transistors. EEPROMs can be programmed and erased in-circuit, by applying special programming signals.

99
Q

PCB

A

PCB
Printed Circuit Board - mechanically supports and electronically connects electronic components or electrical components using conductive tracks, pads and other features etched from one or more sheet layers of copper laminated onto and/or between sheet layers of non-conductive substrate.

100
Q

PPAP

A

PPAP
Production Part Approval Process is used in the automotive supply chain for establishing confidence in suppliers and their production processes.

The purpose of any PPAP is,

  • To ensure that a supplier can meet the manufacturability and quality requirements of the parts supplied to the customer.
  • To provide evidence that the customer engineering design record and specification requirements are clearly understood and fulfilled by the supplier.
  • To demonstrate that the established manufacturing process has the potential to produce the part that consistently meets all requirements during the actual production run at the quoted production rate.

Actual measurements are taken of the parts produced and are used to complete the various test sheets of PPAP.
The PPAP process is designed to demonstrate that a supplier has developed their design and production process to meet the client’s requirements, minimizing the risk of failure by effective use of APQP. Requests for part approval must therefore be supported in official PPAP format and with documented results when needed.

This includes paying for shipping costs, export and import duties, insurance and any other expenses incurred during shipping to an agreed-upon location in the buyer’s country.

106
Q

BSP

A

BSP
In embedded systems, a Board Support Package is the layer of software containing hardware-specific drivers and other routines that allow a particular operating system (traditionally a real-time operating system, or RTOS) to function in a particular hardware environment (a computer or CPU card), integrated with the RTOS itself. Third-party hardware developers who wish to support a particular RTOS must create a BSP that allows that RTOS to run on their platform. In most cases the RTOS image and license, the BSP containing it, and the hardware are bundled together by the hardware vendor.
