作为我之前的好奇心问题的衍生,我有一个后续的好奇心。 6502、VIC 和 SID 芯片有未来和/或应用吗?我知道它们仍在生产和使用。例如,我记得6502是一款完美的小家电控制芯片。 SID 肯定仍然存在于一些“复古”声音合成器中,尽管我猜测它只是被模拟。维多利亚州怎么样?
社区维基问题,因为没有正确答案。
As a derivative of my previous curiosity question I had a followup curiosity. Is there a future and/or an application for the 6502, the VIC and the SID chips ? I know they are still produced, and used. For example, I remember the 6502 makes a perfect controller chip for small appliances. the SID for sure is still present in some "retro" sound synthesizer, although my guess is that it's just emulated. What about the VIC ?
Community wiki question as there's no correct answer.

我会查看 6502.org,包括其 商业支持列表 和项目列表 >。
I would look at 6502.org, including its list of commercial support and list of projects.
我不知道 VIC 和 SID 芯片(专用视频/音频芯片与 CPU 不同),但我看不出有任何理由使用 6502。有大量廉价的低功耗微控制器(例如 Microchip PIC、Atmel) 、TI MSP430 等),它们很容易获得,具有比 6502 更多的 CPU 马力,具有有用的外设(ADC、UART、内置振荡器等),并且具有实时调试功能。为什么要使用已有 30 年历史的微控制器?
I dunno about the VIC and SID chips (special purpose video / audio chips are different than a CPU), but I don't see any reason to use a 6502. There are tons of cheap low-power microcontrollers (e.g. Microchip PIC, Atmel, TI MSP430, etc) that are readily available, have more CPU horsepower than a 6502, have useful peripherals (ADCs, UARTs, built-in oscillator, etc), and have real-time debugging features. Why use a 30-year-old microcontroller?
我认为他们的未来是有限的。我不知道仍在生产多少数量,但您必须计算出,甚至 486 的生产数量也可能比 6502 多得多。因此,尽管 486 对于某些应用可能有些过分,但它的可用性决定了它的价格,因此使其对设备制造商更具吸引力。
然后,正如您所说,现在可以轻松模拟 6502、VIC 和 SID 芯片的功能 - 即使在软件中也是如此。因此,这可能会降低对这些芯片的需求,因为模拟它的成本可能会更低。
I would think their future is limited. I don't know what kind of quantities are still being produced but you have to figure even the 486 is probably being produced in far greater quantities than the 6502. So even though the 486 might be overkill for some applications its availability determines its price thus making it more attractive to device manufacturers.
Then, as you say, the functionality of the 6502, VIC, and SID chips are easily emulated these days--even in software. So that might drive the demand for those chips down since its probably cheaper to emulate.
成本意味着它每年仍能销售数百万台。 6502是最便宜的8位CPU;没有像 Stm8 这样的 6 个月交货时间,没有像 pic 或 8051 这样的脑残内存模型,也没有像 avr、pic、msp430 这样价格过高的产品。为了更便宜,你必须选择 4 位,这是非常有限的。诚然像stm32f030这样的arm芯片只贵几毛钱,但有一家叫沃尔玛的公司要求产品尽可能便宜,以便制造商削减成本。
Cost means it still sells millions of units each year. 6502 is cheapest 8 bit CPU; doesn't have 6 month lead time like Stm8, braindead memory model like pic or 8051 or overpriced like avr, pic, msp430. To go cheaper you have to go 4 bit which is very limited. Admitedly arm chips like stm32f030 are only a few cents more but there is a company called Walmart that asks for products to be as cheap as possible so manufacturers cut cents of costs.
