Kim Rowe at RoweBots Research let me know his company now offers Unison Version 5 and the open-source version of Unison Version 4. These two ultra-tiny embedded-Linux and POSIX-compatible real-time operating systems (RTOSs) let product developers who use--or want to use-- the Renesas SH-2A microcontroller (MCU) family work with Linux for the first time.

Earlier in 2009, Micrium introduced its μC/OS-III real-time kernel, a real-time operating system (RTOS) that use the ARM7/9, Cortex-MX, Nios-II, PowerPC, Coldfire, i.MX, Microblaze, H8, SH, M16C, M32C, or Blackfin processors, among others.

When you develop products that will employ a Universal Serial Bus (USB) connection, you might need to dive into the nitty-gritty analysis of bus traffic. Previously, that meant struggling through binary, hexadecimal, or other low-level information to find and then interpret transactions. No software developer or hardware engineer wants to work at that level when tools can distance them from bits and bytes.
