It's very tempting to claim that the Anker PowerPort Atom PD 2 could fly me to the moon. Compared with the Apollo 11 Guidance Computer it runs at ~48 times the clock speed with 1.8x the program space. The most powerful CPU in the table is from the Anker PowerPort Atom PD 2 (CYPD4225). If you include the parity bit in each wordĪRM Cortex-M0 32-bit implementing ARMv6-MĬPU description Memory Functional overview The Apollo 11 spacecraft carried 3 humans to the moon and back in 1969.Īpollo 11 Moon Landing Guidance Computer (AGC) Power of the Apollo 11 Guidance Computer (AGC). See how the CPUs contained in recent USB-C wall chargers compare to the I think it is healthy to compare historical and modern computing. Moonjs is the logical next step that uses Emscripten compiler to convertĮxisting C code into asm.Apollo 11 vs USB-C Chargers Apollo 11 Guidance Computer (AGC) vs USB-C Chargers Was very positive and convinced me of the suitablity of the HTML5/javascript combination in writing With online javascript-based simulation ( svtsim and hemosim) Make it possible to write computationally extensive applications in javascript. Recent advances in the javascript language - such as optimized engines, ahead-of-time (AOT) compilation, and asm.js. Lots of useful information and a comprehensive bibliography. "The Apollo guidance computer : architecture and operation" by Frank O'Brien. The excellent Virtual AGC website by Ronald Burkey and Launches to allow astronauts monitor the progress of the launch vehicle.įor many more examples and details about AGC, its programming and operation, two great sources are In fact, this program was used during the boost phase of Saturn V If instead of Verb 06, we use Verb 16, the same values are shown and updated constantly untilĪ different command is entered. During an actual launch (or a simulated one), they would update with current values. Unfortunately, we are not going to space today, so all three show 00000 and will continue toĭo so. It shows the current velocity (top row), altitude rate (middle row) and altitude (bottom row). Let's try some spaceflight related programs! Enter.You can get the statistics for the next bank. The middle row is the bank number and the third row is aīugger word appended to the end of each bank to make the checksum the correct value. Shows the checksum in octal, which should be either the bank number or its 1-complement (e.g., for bank 3Įither a value of 00003 or 77774 is acceptable). The fixed memory is divided into 38 banks, each containing 1024 (1K) 15-bits words. It shows the checksum of the first bank of the fixed memory (the so-called core-ropes in AGC terminology). Start program P00, the idle program, by entering.The middle one minutes and the topmost one hours elapsed since AGC powered up. Test the DSKY lamps (digits and indicators) by entering.For example, Verb 06 can be used to display the value of near 100 different memory locations selected based on the given Noun. The simulated DSKY communicates with a simulated AGC, which in turn runs a copy of Colossus 249, the flight software that flew on the Apollo 9 Command Module.ĭSKY human interface was built around the concept of Verbs and Nouns.
