The EE-Auto platform, which combines Enea's OSE Epsilon real-time operating system (operating system) Real-Time Operating System - (RTOS) Any operating system where interrupts are guaranteed to be handled within a certain specified maximum time, thereby making it suitable for control of hardware in embedded systems and other time-critical applications. (RTOS) with an optimized TCP/IP stack, flash file system, and development tools, provides an ideal platform for hosting MAC7111-based automotive infotainment control applications that require small code size and fast, reliable real-time response. EE-Auto is available for all MAC71xx family processors and runs out of the box on MAC7111 evaluation boards, which include an OSE Epsilon demonstration CD and motor control application example. "Electronic systems are controlling a growing number of functions in modern cars, everything from ABS brakes and engines to telematics," said Michael Christofferson, director of product marketing at Enea. "EE-Auto gives automotive OEMs who are designing MAC7111-based automotive control systems the advanced real-time scheduling, memory management, interrupt processing, I/O (Input/Output) The transfer of data between the CPU and a peripheral device. Every transfer is an output from one device and an input to another. See PC input/output. I/O - Input/Output and networking functionality needed to reliably manage this complex set of functions." "The MAC7111's high performance, integrated flash, and versatile I/O architecture make it ideal for tackling compute-intensive automotive applications with tight size and memory constraints," continued Christofferson. "OSE Epsilon's compact size and fast, predictable real-time response make it a perfect fit for the MAC7111, and an excellent platform for hosting sophisticated automotive and telematics applications." The MAC7111 is a pin-compatible member of a family of flash-equipped 32-bit microcontrollers optimized for embedded automotive applications like airbag, instrument cluster and body control. Featuring a 32-bit ARM7/TDMI-S(TM) RISC RISC in full Reduced Instruction Set Computing Computer architecture that uses a limited number of instructions. RISC became popular in microprocessors in the 1980s. core operating at speeds of up to 50 MHz (MegaHertZ) One million cycles per second. It is used to measure the transmission speed of electronic devices, including channels, buses and the computer's internal clock. A one-megahertz clock (1 MHz) means some number of bits (16, 32, 64, etc. , the MAC 7111 is equipped with 512 kbytes of program flash EEPROM (Electrically Erasable Programmable ROM) A rewritable memory chip that holds its content without power. Although EEPROMs spawned flash memory, EEPROMs are byte addressable at the write level, whereas flash chips must erase a block of bytes before rewriting. , 32 kbytes of data flash EEPROM, and 32 kbytes of RAM. The MAC7111 also features a 16-channel, 10-bit analog-to-digital converter, a 16-channel enhanced modular I/O timer subsystem, four enhanced serial communications interfaces, four CAN 2.0 interfaces, two serial peripheral interfaces (SPI (1) (Stateful Packet Inspection) See stateful inspection. (2) (Service Provider Interface) The programming interface for developing Windows drivers under WOSA. ), an I2C bus interface and a JTAG (Joint Test Action Group) An IEEE standard for boundary scan technology. See scan technology. JTAG - Joint Test Action Group test port with real-time instruction trace support. EE-Auto's OSE Epsilon RTOS is a high-performance real-time kernel optimized for resource-constrained applications. Occupying as little as 4 kbytes of memory, OSE Epsilon features integrated error handling, a context switching speed of 300 nsec, full pre-emptibility, and a worst-case interrupt latency of 1 usec. OSE Epsilon offers both priority-based and deadline scheduling, a key requirement for automobile control applications with hard real-time constraints. EE-Auto features a complete network solution, including an optimized TCP/IPv4 stack, a Web server, an embedded file system and Internet utilities. "Enea has a reputation for product quality and reliability, making the company an ideal choice to support Freescale's MAC7111," said Bill Krakar, tool program manager for Freescale. "We expect our automotive customers will appreciate the robustness of the Enea MAC7111 EE-Auto platform." EE-Auto supports integrated development environments from GNU gnu (n  ) or wildebeest (wĭl`dəbēst'), large African antelope, genus Connochaetes. , ARM, Green Hills Software, and IAR Systems. Enea's own OSE Soft Kernel simulation tool allows designers to develop and test their code on a PC without the need for the target hardware. Enea also offers an RTOS-aware system analysis and profiling tool, OSE Illuminator illuminator (light box),n a source of light with uniform intensity for viewing radiographs. illuminator the source of light for viewing an object. , that enables programmers to monitor, control and collect data for applications viewed as a sequence of events (such as context switches and message-passing between processes). OSE Illuminator lets designers debug multiple MAC7111 nodes simultaneously, graphically view all processes and process information running on each node, set breakpoints on events, profile CPU CPU in full central processing unit Principal component of a digital computer, composed of a control unit, an instruction-decoding unit, and an arithmetic-logic unit. performance, and monitor/fine tune memory usage. EE-Auto is available immediately for MAC7111 processors. Pricing starts at $8,000 for a single developer's seat.
