# Agnus

The one thing I've always liked about Amiga computers is that the custom ICs always have interesting names.
At first glance Agnus seemed like a mis spelled Agnes. When I dove into the manuals I saw the interesting work that the Agnus IC needs to do.

You can consider the Agnus as the direct memory access broker in the Amiga.

A practical example of Agnus usage

* Noise Tracker
* mod data
* Paula

Noise Tracker request0 mod playback on Paula

* CPU interrupt
* Agnus DMA interrupt
* Data playback on Paula

Noise Tracker request1 on Paula
* Agnus DMA interrupt
* Data playback on Paula

As you can see the central processing unit is interrupted only once; all consecutive communications goes through the Agnus IC immediately to Paula.
This Architecture Made it possible to use such a light CPU while The machine did extreme heavy lifting, for it's memory footprint.

Quote
>Agnus is the Address Generator Chip. Its main function, in chip area, is the RAM Address Generator and Register Address Encoder which handles all DMA addresses. The 8361 Agnus is made up of approximately 21000 transistors and contains DMA Channel Controllers. The Blitter and Copper are also contained here. Originally Agnus was fabricated in 5 μm manufacturing process like all OCS chipset.

Agnus features:

>Memory controller ("Chip" memory that can be accessed by the processor and the chipset)
The Blitter, a bitmap manipulator. The Blitter is capable of copying blocks of display data, or any arbitrary data in the chip memory, at high speed with various raster operations as well as drawing pixel perfect lines and filling outlined polygons, while freeing the CPU for concurrent tasks.

“We must #protest. #Interrupt. #Disrupt. #Strike.
And above all — prepare for massive #boycotts.
Not temporary boycotts. Not symbolic ones.
Permanent #divestment from the #monopolies that bankroll #authoritarianism and manufacture #oligarchs.”

Starker #Flipper-Zero-Konkurrent kommt mit #Linux und #Tastatur

Vielfältige Schnittstellen, #Linux, ein #Farbdisplay und eine integrierte #Tastatur machen #Interrupt zu einem ernst zu nehmenden Konkurrenten des Flipper Zero.

Das #Hackingtool Flipper Zero hat sich in den vergangenen Jahren bereits einen Namen gemacht. Auf #Kickstarter läuft nun eine #Finanzierungskampagne für ein vergleichbares Tool namens Interrupt, das im Gegensatz zum Flipper Zero...

This handheld Linux PC is made for wireless hacking (Crowdfunding a Raspberry Pi-powered Flipper Zero alternative with a QWERTY keyboard)

The Interrupt is a handheld computer with a QWERTY keyboard for thumb typing, a 3.5 inch IPS LCD color display, and a Kali Linux-based operating system. But while you can use it as a general purpose device, it’s really designed as a sort of Flipper Zero-like system for tinkering with nearby wireless devices.

In addition to WiFi 5 and Bluetooth, the handheld has a CG1101 sub 1 GHz radio, […]

Catastrophic thinking focuses on the worst possible outcome and leads us there.

We can interrupt the process by consciously shifting our attention to something positive, including the wisdom gained from a bad experience that will most certainly improve our future.

Today's mindfulness challenge is to pay attention to negative thought patterns, and practice shifting them.

Although my #cat is a dedicated human bathroom stalker #kitty - he hates it when humans #interrupt him while he has solo grooming time in there. I accidentally walked in on him & he growled before this photo was taken.

I took the hint. Fled the bathroom.

When people come to my desk to ask basic #tech things, like how to enable something in #InternetExplorer... I mean, they need to actually leave their chair, physically pass through 3+ doors, #interrupt me from my work to use my browser to search the Internet...

How #shit must Internet Explorer be, if you cannot use it to search the internet!?
