PLS’s UDE 5.0 with hypervisor awareness supports development of virtualized applications

PLS Programmierbare Logik & Systeme provides developers with the latest version 5.0 of its Universal Debug Engine® that offers a wide range of completely new and significantly enhanced functions for professional debugging and testing of embedded systems. The UDE 5.0, presented for the first time at embedded world 2019 in Hall 4, Booth 4-310, now supports the development of virtualized applications for ARM Cortex-A53 by providing hypervisor awareness for the LynxSecure hypervisor from Lynx Software Technologies.

At present there is a trend to consolidate multiple applications, which in the past used separate hardware, on a single computing platform. However, different requirements in terms of safety, security and real-time behavior demand strict isolation, which can only be achieved by virtualization. With the hypervisor awareness, the developer can now use the extensive debug capabilities of the UDE for the development of virtualized applications too. Specific features of the ARM Cortex-A53, such as two-stage address translation or the support of virtual interrupts are handled transparently for the users. The hypervisor awareness of UDE enables the user to debug a bare-metal application as usual and as if it was running on real hardware instead of being encapsulated within a virtual machine (VM). If required, UDE provides also support for debugging and system analysis of the hypervisor itself. For each individual VM, both the state and the contexts can be displayed. In addition, information about the memory layout of the individual VMs as well as the mapping of the virtual memory addresses to physical memory addresses is provided by UDE.

Handling of large quantities of recorded trace data has been further simplified and improved in the UDE 5.0. Special attention was paid to visualization. For example, the time-accurate display of the executed functions and operating system tasks in the UDE Execution Sequence Chart can now be sorted and filtered according to different criteria. Links allow an easy navigation from the recorded functions to their source code. In combination with the add-in for the support of real-time operating systems according to the OSEK (Open Systems and their Interfaces for the Electronics in Motor Vehicles) standard, the operating system tasks and associated runnables can be clearly displayed and measured. An export function for the Best Trace Format (BTF) also allows further processing using popular third-party task analysis tools.

As a true multicore debugger, the UDE 5.0 also supports the visualization of the states and control of all cores of a multicore system within a uniform user interface. Even more efficient than before, for example, is the handling of variables that the compiler made it visible only for one specific core. In the watch windows of UDE such core-local variables are now separated by different colors according to the respective core. Until now this coloring was only applied to windows assigned to a specific core and for status information of the individual cores.

The UDE 5.0 also features numerous improvements and enhancements in terms of supported microcontrollers. Debug functions for 64-bit architectures, for example for the ARM Cortex-A53, have been consistently expanded. The ARM Cortex-R52 32-bit processor and the NETX 90 Cortex-M microcontroller have been added as completely new devices from the ARM world. The UDE 5.0 also offers dedicated debug support for the new PowerArchitecture-based Chorus SPC58NH92x devices from STMicroelectronics and the MPC5775B/MPC5775E microcontrollers from NXP. The latter MCUs target automotive and industrial battery management and inverter applications that require advanced performance. UDE’s Nexus trace support is available also for these devices and provides extensive functions for exact run-time analysis such as profiling, code coverage and the visualization of call graphs.

In particular, the microcontrollers of Infineon’s TC3xxx family benefit from the extended debug and trace functions of UDE 5.0. In addition to the multicore debug functions and depending on the specific controller, trace support is available for non-invasive debugging and system analysis: For the TC35x the new MCDSlight and for the TC38x the basic trace functionality of miniMCDS. The latter is also available to the developers in the basic license of the UDE.

A special multi-AURIX adapter is now available for target communication with the Universal Access Device 3+ (UAD3+). That adapter was developed by PLS in order to meet the special requirements of fail-safe and fail-operational systems, which provide redundancy based on two AURIX devices with two separate debug interface. Together with the UDE 5.0, the adapter allows fully synchronized stop-mode debugging: break, single-step operation and restart – as well as synchronous stopping of the peripheral units of both microcontrollers.

Epson shipping samples of a 32-bit microcontroller with dedicated sound hardware

Seiko Epson Corporation (TSE: 6724, "Epson") has begun shipping samples of the S1C31D50, a 32-bit microcontroller with dedicated sound hardware for 2-channel sound. Epson plans to produce 200,000 units per month of each model.

Sound is becoming an increasingly popular feature in home electronics, remote controllers for home appliances, industrial devices, health and fitness equipment with guidance systems, and alarms in office buildings, shopping complexes, and factories. This MCU is ideal for all these applications. An ARM® Cortex®-M0+ processor integrated with a dedicated HW Processor provides 2-channel sound on a single MCU chip. The use of two channels enables music and voice to be played simultaneously, lending audio guidance greater elegance and warmth. Voice speed can also be flexibly adjusted.

The MCU’s dedicated HW Processor sound hardware boasts a pair of special features. First, the HW Processor plays sound without requiring CPU resources, so CPU resources can be allocated to other processes even during sound playback. The use of a high-compression algorithm (16 kbps @ 16 kHz) shrinks the size of sound data memory, making it possible to provide a large amount of sound data and sound data in multiple languages. Epson also offers a PC tool that provides a development environment for easily creating sound data in Japanese, English, Chinese, and Korean without studio recording. 
Second, the MPU also has a self-memory check function that can detect failures in built-in RAM, built-in Flash, and external SPI-Flash memories without using CPU resources.

Epson is committed to helping its customers improve the performance of their products with solutions that leverage Epson’s efficient, compact, and precision technologies.

* A processor designed by U.K-based ARM Limited, the ARM® Cortex®-M0+ is ARM’s most energy-efficient processor and by far the most widely used processor in the market.

Key Product Features

1. Dedicated hardware block for independently executing functions. The HW Processor executes the following functions without using CPU resources:

Sound play processing

  • 2-channel mixing sound (for playing background music + voice)
  • Voice speed conversion (playback speed adjustable in 5% increments between 75% and 125%)
  • The sampling rate of 15.625 kHz is high enough for background music as well as voice.
  • High-compression voice decoding algorithm with high sound quality (16/24/32/40 kbps)

3. Development environment

Epson sound creation PC tool

  • Studio recording is not needed. Simply use the PC tool to create all the sound data you need (languages supported: Japanese, English, Mandarin Chinese, Korean)
  • Sound data, which is assigned a number in the PC tool, can be played back by specifying the assigned number in the HW processor register, so there is no need to create and evaluate codes for linking sound data, etc.
  • Your WAV format sound data is easily imported into the PC tool
