August 18, 2009 — Green Hills Software announced the latest firmware release of its hardware-assisted microprocessor debugging solution, the Green Hills Probe. In combination with Green Hills Software’s MULTI software development environment, the Green Hills Probe enables software developers to gain the control and visibility required to perform board bring-up, device driver development, and other system debugging tasks in the least amount of time and with the lowest development cost. This release of the Green Hills Probe provides support for symmetric multiprocessing (SMP) operating systems, such as Green Hills Software’s INTEGRITY real-time operating system. Green Hills Probe enables a seamless and powerful SMP debugging experience by providing synchronized multi-core run-control, inter-core cache coherency features, and intelligent inter-core breakpoint management. Application and device driver developers will be able to find and fix bugs faster, resulting in faster time-to-market for end products.The release adds support for the latest microprocessors including ARM Cortex A8-based processors - such as the Texas Instruments OMAP 3530 and Freescale i.MX515, the dual core Freescale MPC8641D, and a major overhaul of ColdFire support, including the MCF5222x, MCF225x, and MCF227x processors.About the Green Hills ProbeThe Green Hills Probe is the fastest and smartest debug probe ever built. Harnessed through the MULTI integrated development environment or a fully scriptable Web 2.0 interface, the third-generation Green Hills Probe helps embedded developers find and fix bugs faster than ever before. With download rates in excess of 10 MB per second, Gigabit Ethernet, USB 2.0 High Speed, and a flexible electrical interface, the Green Hills Probe will debug a wider range of CPUs faster than any other probe. The Green Hills Probe uses hand-placed custom logic and a highly optimized software path to attain its unprecedented speed.The Green Hills Probe brings a new level of intelligence and versatility to the world of JTAG debug probes. On-board flash programming support for virtually every NOR flash part available, built-in Python scripting with full access to all JTAG and debug port functionality, and a fully scriptable Web 2.0 interface enable the Green Hills Probe to be used for every phase of the product cycle.Built with INTEGRITYThe Green Hills Probe is powered by Green Hills Software’s INTEGRITY, the leading market share high-reliability real-time operating system. The INTEGRITY RTOS’s partitioning architecture and ultra-fast response time enabled the creation of a probe that is modular, reliable, and easy to use while attaining performance levels that have never before been achieved.

Army Depends on INTEGRITY-178 tuMP RTOS for Improved Data Modem - Nov 12, 2020. Sectigo and Green Hills Software Partner to Help Manufacturers Protect Endpoint Devices - Nov 2, 2020. Green Hills Software Expands Leadership in Automotive Cybersecurity - Oct 28, 2020.

SANTA BARBARA, Calif., Nov. 12, 2020 /PRNewswire/ -- Green Hills Software, the worldwide leader in high-assurance operating systems, today announced that its INTEGRITY^®-178 Time-Variant Unified Multi-Processing (tuMP™) RTOS was selected by the U.S. Army for the operating system upgrade to the Improved Data Modem (IDM-401) program. The originally fielded IDM software functioned on a single core of its multicore CPU. This limited overall system throughput and led the IDM program to find a DO-178C DAL A compliant solution that provided optimal core utilization and greater processing power from the existing IDM multicore CPU. The primary factor in the selection of INTEGRITY-178 tuMP was the low-risk path for the delivery of its DAL A certification artifacts on a multicore architecture for the IDM processor. Other key factors included the built-in multicore interference mitigation and the ability to utilize all available cores in an efficient, optimal and bounded manner.

The IDM-401 is the common solution for digitizing Army Aviation and is fielded on every modernized, rotary-wing Army aircraft, including the CH-47 Chinook, AH-64 Apache, and UH-60 Black Hawk. The IDM enables connectivity to multiple radios used by rotary-wing aircraft and the Blue Force Tracker transceiver, as well as providing the means for rapid data transfer. The program supports Open Systems Architecture (OSA), Future Airborne Capability Environment (FACE), and Common Operating Environment (COE) standards and interoperability.

Multicore interference is one of the biggest challenges facing avionics system integrators today. All multicore processors include some shared resources, such as memory and I/O, and interference results when access to a shared resource is blocked due to it being in use by a different processor core. This issue is of such concern that the Certification Authority Software Team (CAST) has published a position paper called CAST-32A dedicated solely to providing guidance for interference identification, mitigation, and verification in multicore systems.

The INTEGRITY-178 tuMP multicore RTOS addresses the interference challenges discussed in CAST-32A with its Bandwidth Allocation and Monitoring (BAM) capability. BAM was developed to DO-178C DAL A objectives and will mitigate the interference risks for the IDM. The INTEGRITY-178 tuMP BAM monitors and enforces the bandwidth allocation of the chip-level interconnect to each of the cores, thereby guaranteeing a particular allocation of shared resources. The supported bandwidth management technique emulates a high-rate hardware-based approach to ensure continuous allocation enforcement. This capability greatly lowers integration and certification risk while also enabling the integrator to manage significant software retest costs that would occur when a software application changes or is added.
