| Welcome to e-News from IAR Systems |
Many users of IAR Embedded Workbench are involved in the development of safety-related systems. Roland Lips, CEO of SCIOPTA Systems, describes the benefits of using a certified RTOS for compliance with IEC61508.
No matter how many new microcontroller families there are, 8051 is still a popular choice. This month we offer an article about the 8051 memory architecture and using IAR Embedded Workbench.
New versions of the IAR Embedded Workbench products for ARM, Atmel AVR32, Renesas M16C/R8C and NEC 78K have been released this summer and we also have a new ARM Cortex-M3 kit for Toshiba's TMPM330.
Best regards,

| Important points in 8051 programming: 8051 data memory architecture |
8051 is an old microcontroller released by Intel in 1980. After its release several semiconductor vendors started offering 8051-based microcontrollers, and it is still widely used with a variety of improvements/enhancements made to it. While it’s designed to improve efficiency considerably when programming in assembler, many instances have been observed where it’s challenging to program in standard C language in terms of memory capacity, without taking special consideration.

| RTOS for safety-related systems |
There are two main technologies of real-time operating systems. Shared Memory RTOS where the user is responsible for protecting memory from mutual access by using specific RTOS tools (e.g. semaphores) and Direct-Message Passing RTOS where data is encapsulated in messages used also for inter-process communication and synchronization.
