The FPGA Semaphore IP example provides a simple reusable FPGA VI to implement a semaphore within your LabVIEW FPGA application. It is intended to be used in situations where you are accessing a shared resource from multiple location of your diagram and need to manual block other accesses while one access is in progress. 

Before using the semaphore the first time in your diagram you must call the Reset function to prime the process.

When you want to use a shared resource you call the Acquire function. You can pass in a Timeout value to specify how long you want to wait for the semaphore if necessary. If the semaphore is available and the acquisition was successful, the Timed Out? return value will be False. If it is True then the semaphore is not available.

Seattle-based Clipper Vacations is a widely recognized provider of sea travel options, including regular ferries to and from Canada, along with tourist excursions for whale watching and other activities. It was struggling with daily network outages across its fleet, costing the business thousands of dollars at a time and causing grief for its staff and customers alike. Additionally, Clipper Vacations requires partner support in British Columbia, Canada, in order to properly manage its fleet and back office, and a solution would need to be accessible by multiple organizations.

Recognizing that Clipper Vacations needed to arm an IT team that wasn’t present across the company’s fleet at all times, Semaphore investigated how a cloud-based management platform might solve a major challenge. The company reviewed Clipper Vacations’ infrastructure, and found that it needed a complete overhaul in order to be able to deliver what it was intended to do. Our team employed a Meraki-focused solution, ensuring that the company’s cameras, wifi, and other network requirements were all manageable through a virtual environment, resulting in an immediate decrease of the company’s prior financial costs due to these network issues.

A black swan event is an incident that occurs randomly and unexpectedly, and has a major effect on operations. The phrase illustrates the frailty of inductive reasoning and the danger of making sweeping generalizations from limited observations.

Semaphores are commonly use for two purposes: to share a common memory space and to share access to files. Semaphores are one of the techniques for interprocess communication (IPC). The C programming language provides a set of interfaces or "functions" for managing semaphores.

I didn't find the time or energy to finish writing up the final two stages of this project once I'd finished it, which was a shame, as the Semaphore Line proved to be an excellent long distance walk - the sort of walk that really deserves a guide book.

However, I've now (March 2012) added a few notes and photographs to cover the final two days of the walk. I can finally call this project complete!

If you decide to do this walk, and then want a interesting return walk to London, I suggest following the London to Portsmouth inland waterway, another product of the Napoleonic wars.
