Vectorized ZX Spectrum Screen Rendering

A vectorized method for rendering the ZX Spectrum screen on modern devices.

Rendering the ZX Spectrum Screen

Using C# to convert the ZX Spectrum screen to a pixel based format for rendering on modern devices.

A Bit of Vectorization

Speeding up a function using SIMD vector operations.

A Pointless Performance Optimisation

Taking a simple, fast function and changing it into a complex, faster function.

Evaluating Poker Hands

Finally we're in a position to actually evaluate poker hands using my favourite hobby of gratuitous bit twiddling.

More Bit Representations

Let's look at another way to represent cards using bits that will be much easier to work with when we finally get around to evaluating poker hands.

Card Combinations

Before we can start evaluating five card poker hands we actually need to get some five card poker hands. So we need some code to produce five card hand combinations from a full deck of cards.

A Set of Cards

First in a series of post where I discuss how to evaluate poker hands using C# and excessive bit twiddling.

Unsafe C# - Converting Longs to Byte Arrays

In my previous post on converting enums to bytes I didn't achieve any noticeable speed up using unsafe code, probably because the safe conversion is so simple. What about a more complex conversion that could be done in a different way using unsafe code? A 64-bit long can

Unsafe C# - Converting Enums to Bytes

Whilst working on my Cards project I needed to convert enum values into bytes. The enums in question have ints as their underlying types rather than bytes (even though I could make the underlying type byte everyone pretty much expects all enums will have ints as their underlying type so
