问题很简单，就是想让它帮我解析一个寄存器的各个 bit 代表的含义。这个寄存器读出来是 16 进制的。它需要转换成二进制。根据公开的 ieee 标准每个 bit 都有特定的含义。但是它转换成二进制的时候，总是会弄错。比如 bit2 是 1 ，它理解成 0.是我的提问方式不对吗？还是选择的模型不对？我用的是 gpt-4o 。请大家指点一下。

Parsing Ethernet PHY status register

Message From You:

get the value of ethernet phy register 1(status register). Its value is 0x796d. Please help me parse the value

Message From ChatGPT:

Certainly! The value of the Ethernet PHY status register (register 1) is 0x796d. To parse this value, we need to understand the typical bit definitions for this register. The exact bit definitions can vary depending on the specific PHY chip, but I'll provide a common example based on the IEEE 802.3 standard for PHY status registers.

The common bit definitions for the status register (register 1) are:

Bit 15: 100BASE-T4 Capable
Bit 14: 100BASE-X Full Duplex Capable
Bit 13: 100BASE-X Half Duplex Capable
Bit 12: 10 Mbps Full Duplex Capable
Bit 11: 10 Mbps Half Duplex Capable
Bit 10: 100BASE-T2 Full Duplex Capable
Bit 9: 100BASE-T2 Half Duplex Capable
Bit 8: Extended Status
Bit 7: Unidirectional Enable
Bit 6: MF Preamble Suppression
Bit 5: Auto-Negotiation Complete
Bit 4: Remote Fault
Bit 3: Auto-Negotiation Ability
Bit 2: Link Status
Bit 1: Jabber Detect
Bit 0: Extended Capability

Given the value 0x796d, let's convert it to binary:

0x796d = 0b0111100101101101

Now, let's map this binary value to the status register bits:

Bit 15: 0 (100BASE-T4 Capable: No)
Bit 14: 1 (100BASE-X Full Duplex Capable: Yes)
Bit 13: 1 (100BASE-X Half Duplex Capable: Yes)
Bit 12: 1 (10 Mbps Full Duplex Capable: Yes)
Bit 11: 0 (10 Mbps Half Duplex Capable: No)
Bit 10: 0 (100BASE-T2 Full Duplex Capable: No)
Bit 9: 1 (100BASE-T2 Half Duplex Capable: Yes)
Bit 8: 0 (Extended Status: No)
Bit 7: 1 (Unidirectional Enable: Yes)
Bit 6: 1 (MF Preamble Suppression: Yes)
Bit 5: 0 (Auto-Negotiation Complete: No)
Bit 4: 1 (Remote Fault: Yes)
Bit 3: 1 (Auto-Negotiation Ability: Yes)
Bit 2: 0 (Link Status: No)
Bit 1: 1 (Jabber Detect: Yes)
Bit 0: 1 (Extended Capability: Yes)

So, the parsed values are:

100BASE-T4 Capable: No
100BASE-X Full Duplex Capable: Yes
100BASE-X Half Duplex Capable: Yes
10 Mbps Full Duplex Capable: Yes
10 Mbps Half Duplex Capable: No
100BASE-T2 Full Duplex Capable: No
100BASE-T2 Half Duplex Capable: Yes
Extended Status: No
Unidirectional Enable: Yes
MF Preamble Suppression: Yes
Auto-Negotiation Complete: No
Remote Fault: Yes
Auto-Negotiation Ability: Yes
Link Status: No
Jabber Detect: Yes
Extended Capability: Yes

Note that these interpretations are based on a common definition of the status register. For exact bit definitions, you should refer to the datasheet of the specific PHY chip you are using.

Message From You:

Bit 2 is 1 ，why you say is 0. Please check again

Message From ChatGPT:

I apologize for the oversight. Let's re-evaluate the binary representation of the value 0x796d and correctly interpret bit 2.

The hexadecimal value 0x796d converts to binary as follows:

0x796d = 0b0111100101101101

Now, let's break down the binary value into individual bits:

Bit 15: 0
Bit 14: 1
Bit 13: 1
Bit 12: 1
Bit 11: 1
Bit 10: 0
Bit 9: 0
Bit 8: 1
Bit 7: 1
Bit 6: 0
Bit 5: 1
Bit 4: 1
Bit 3: 0
Bit 2: 1
Bit 1: 0
Bit 0: 1

So, the corrected bit values are:

Bit 15: 0 (100BASE-T4 Capable: No)
Bit 14: 1 (100BASE-X Full Duplex Capable: Yes)
Bit 13: 1 (100BASE-X Half Duplex Capable: Yes)
Bit 12: 1 (10 Mbps Full Duplex Capable: Yes)
Bit 11: 1 (10 Mbps Half Duplex Capable: Yes)
Bit 10: 0 (100BASE-T2 Full Duplex Capable: No)
Bit 9: 0 (100BASE-T2 Half Duplex Capable: No)
Bit 8: 1 (Extended Status: Yes)
Bit 7: 1 (Unidirectional Enable: Yes)
Bit 6: 0 (MF Preamble Suppression: No)
Bit 5: 1 (Auto-Negotiation Complete: Yes)
Bit 4: 1 (Remote Fault: Yes)
Bit 3: 0 (Auto-Negotiation Ability: No)
Bit 2: 1 (Link Status: Yes)
Bit 1: 0 (Jabber Detect: No)
Bit 0: 1 (Extended Capability: Yes)

So, the parsed values are:

100BASE-T4 Capable: No
100BASE-X Full Duplex Capable: Yes
100BASE-X Half Duplex Capable: Yes
10 Mbps Full Duplex Capable: Yes
10 Mbps Half Duplex Capable: Yes
100BASE-T2 Full Duplex Capable: No
100BASE-T2 Half Duplex Capable: No
Extended Status: Yes
Unidirectional Enable: Yes
MF Preamble Suppression: No
Auto-Negotiation Complete: Yes
Remote Fault: Yes
Auto-Negotiation Ability: No
Link Status: Yes
Jabber Detect: No
Extended Capability: Yes

Thank you for pointing out the mistake.

LLM 不擅长逻辑计算，你这种场景，不如让 ChatGPT 给你写个脚本更有效

或许因为你不懂 LLM ？ dog：）

llm 是序列预测啊，本质上就是成语接龙，不借助其它技术没啥计算能力

LLM 不擅長邏輯計算，但可以寫腳本。這表示寫腳本的機器人可以不擅長邏輯計算。

其實 LLM 也不擅長寫腳本, 因為它不擅長邏輯計算.

它只是複讀機, 把別人寫過的腳本複讀出來, 讓人覺得它會寫腳本.

你叫它使用代码和相关计算工具给你做，它就会调用工具或写代码做，正确性就高了

语言模型适合写作文，不适合做算数

简单来讲，chatgpt 这类东西是看完了一千万本书，然后建立了 x 后面应该是 y1 还是 y2 的预测模型

现在拿着 1+2=？问它，它发现 3 这个字符是概率最大的

但更复杂的算数场景它未必能正确预测出正确的下个字符

@cvbnt 今天我问了相同的问题，Wolfram GPT 也没有完全算对。

为什么 chatgpt 连 16 进制转二进制都会搞错？
