Renesas is one of the leading semiconductor companies in the world and it offers one of the best microcontrollers in the industry – the Renesas H8SX. Development for the H8SX is suited to appliances which require touch panel graphics at low cost and other appliance related functions. It requires a variety of components and systems to put together a total solution and this is what the Unison package does for the H8SX.

First, Unison offers a broad set of technology which are applicable for appliance applications that the H8SX is currently being used for or has targeted. These applications require:

• Motor control – both drives and motion control
• Smart sensors
• Modems of various flavors
• Touch Panel Color Graphics
• TCP/IP

Most applications are high volume with components of DSP algorithms included. The motor control portion for example, requires DSP if maximum efficiency is sought using vector control algorithms. Other examples might involve noise elimination and averaging.

The Unison RTOS development environment for Renesas H8SX offers the following features with which Linux compatible applications can be developed:

• HEW IDE
• A Compiler, Assembler, Linker, Librarian from HEW
• Downloading support from HEW
• A fully functional debugger which works with jtag
• A tiny tiny Linux RTOS including:
  • pthreads
  • mutex
  • semaphores
  • message queues
  • memory pools
  • memory partitions
  • complete I/O services including a file system, serial I/O and networking

This complete offering ensures that users have all the support they need to get a system up and going with minimal effort and risk. It provides full source code so you never need to wonder how things work or why a certain behavior happens.
