  • v1.0.9 released with many fixes and a new sample

    Tags: Release

    Hastlayer v1.0.9 is out! Not many new features but you'll love these bugfixes! Here are the most important changes:

    • Binary operator expressions (like 1 + 2) could in some cases give incorrect results, as could remainder operations (e.g. 9 % 4). These are all fixed now.
    • When you try to transform a piece of code with Hastlayer which Hastlayer doesn't support now better error messages will be surfaced, hinting you what exactly the problem is.
    • And there is also a new Loopback sample that just sends back what you send it from the host PC. This is to test connectivity and use as a generic testbed.

    Hope you'll like these! We've been working on features too, for example adding floating point support, which is mostly done now. We'll talk about it at various conference, starting with ones in Singapore this week!

  • Method inlining, fixed point arithmetic and more - Hastlayer v1.0.8 released

    Tags: Release, Method inlinding, Fixed-point arithmetic

    New year, new Hastlayer version - and we think this one is quite exciting, a lot of improvements arrived! Let's see the highlights:

    • Hastlayer now supports method inlining. Method inlining is when a compiler basically copies the implementation of the method to the place where it's called, thus avoiding the overhead of a method call but making the program bigger. We've added support for the AggressiveInlining attribute so you can instruct Hastlayer to inline methods, just as you'd do the same with the .NET compiler. Since method calls in hardware are also an overhead you can vastly improve the performance of your Hastlayer-using code if it contains many small methods that are frequently called. In our tests with the posit floating point type we cut down execution time by about 40%!

    • Added a 64b fixed-point arithmetic library and made it Hastlayer-compatible. Why is this good? Although making computations with integers is very efficient (and fast), sometimes you need to use fractions. Before the only option with Hastlayer was to scale up your floating point numbers (multiplying them by 10000 for example so there will be no digits after the decimal point), let Hastlayer do the work, then scale them back down. But now we added a 64b number type that can also handle fractions, it's just that there are 31 bits for the digits before the decimal point and 32 bits for the ones after it. But still, the computations will be quite efficient. Nevertheless we're also working on floating point support.
    • Added support for ref and out parameters and made configuration of parallelized code a bit easier.

    So Hastlayer just got a lot better for a lot of programs!

    For more details and the corresponding downloads visit the Hastlayer SDK and Hastlayer Hardware Framework - Xilinx repos on GitHub. Be sure to also check out the updated documentation on how to utilize these new features.

  • Hastlayer v1.0.7 released with a scientific computing example

    Tags: Release, KPZ, Wigner

    The new version of Hastlayer is out! Apart from nice Transformer improvements this also includes one huge example: An implementation of the 3D Kardar-Parisi-Zhang surface growth simulation algorithm. This algorithm simulates how the surface of a material (like a silicon wafer used in chip manufacturing) changes over time. We created the KPZ example in collaboration with the Wigner Research Centre for Physics to test against an existing GPU implementation (testing is upcoming).

    Also, don't forget that the Hastlayer World Tour is still on with three events coming up!
