Renesas works with ASTC to produce virtual platform and fast Linux porting for a new ASIC

Renesas Electronics Europe has announced a collaboration with the Australian consulting firm ASTC in which it developed a new ASIC for a consumer electronics customer and was able to provide a full board support package (secure boot, drivers and OS) before the silicon was available. The speed and efficiency of the development enabled Renesas to produce the ASIC exceptionally fast, while the customer reduced time to market for its new imaging solution.

This next generation ASIC has been designed to significantly enhance image quality and video analytics performance by incorporating custom hardware accelerators into a standard ARM Cortex-based ASIC. While Renesas was engaged on the hardware development, ASTC used its VLAB Virtual Platform solution, together with existing ARM toolboxes and models, to create and integrate a virtual platform for the new Renesas ASIC.

Due to the pre-silicon availability of the VLAB virtual platform for software development, and its advanced hardware/software debug capabilities, the Linux port only took a few weeks. As a result, ASTC delivered a Linux kernel running on the virtual platform well before the silicon was available.

ASTC used VLAB with the standard ARM Virtual Platform Toolbox to accelerate the development and integration of the virtual platform for the new Renesas device. The VLAB ARM Toolbox includes the ARM Cortex-A9 ISS models, the ARM PrimeCell Toolbox, and a QuickStart Reference Virtual Platform. The QuickStart Reference Virtual Platform for customization comprises a pre-integrated platform with sample kernel and test cases, enabling developers to kick-start development by allowing immediate loading and running of software applications.

After assembling the platform for the Renesas device, Renesas took a standard Linux kernel and ported it to this virtual board in just a few weeks, helping the team achieve the goal of having software running long before the hardware is available. Renesas also used this platform to develop the boot code – software that will cause a respin of the ASIC if it is wrong – and test that it was sufficiently robust for the application. Renesas engineers also took advantage of VLAB’s easy scripting API to validate boot-from-UART over a range of baud rate conditions, and of the RealIO™ Ethernet interface to validate boot-from-Ethernet using the same boot tools that the real hardware will use.

ASTC (Australian Semiconductor Technology Company) delivers semiconductor and systems design, embedded software development and other services across global markets and supply chains for automotive, mobile, multimedia, transportation, and aerospace electronics and embedded software.
