| | The Math Coprocessor - PC ComputerNotes |
 | | The Math Coprocessor is a second processor in your computer that does nothing but number crunching for the system. | | | The absence of a math coprocessor in early home computer systems was a matter of keeping production costs down. | | | Most of the older computers (pre-486) were sold without coprocessors. |

| | Unlike Intel's coprocessors, which use the CORDIC [18,19] algorithm to compute the transcendental functions, Cyrix uses polynomial and rational approximations to the functions. | | | Intel 486DX The Intel 486DX is, of course, not solely a coprocessor. | | | One common approach is to replace the WAIT instruction and the first byte of the coprocessor instruction with one out of eight interrupt instructions; the remaining bytes of the coprocessor instruction are left unchanged. |

| | Coprocessor |
| | The coprocessor provides additional instructions, registers, and data types to the system in a manner which is transparent to the user. | | | With the intelligent monitor interface, the coprocessor monitors the instruction stream in parallel with the main processor and processes coprocessor-specific instructions as they hit the instruction stream. | | | The coprocessor then uses a response register to tell the main processor if more data is required to process the instruction. |

| | CHAPTER 6 |
| | Saving coprocessor data is also useful when you want to modify coprocessor behavior by writing certain data to main memory, operating on the data with 8086-family instructions, and then loading it back to the coprocessor data area. | | | However, since the coprocessor cannot handle device input or output, data originates in the main processor. | | | Since the coprocessor does not have jump instructions, you must transfer the status word to memory so that the flags can be used by 8086-family instructions. |

| | IP Workshop - Tygar/Yee: Dyad |
| | When a secure coprocessor verifies that the system software is the correct version, we are assuming that a secure coprocessor has secure, tamper-proof memory which remembers a description of the correct version of the system software. | | | Since secure coprocessors' identity-proofs can be based on a zero-knowledge protocol, no secret information needs to be stored in smart-cards unless smart-cards are to also aid users in authenticating themselves to systems, in which case the only secrets would be those belonging to the users. | | | We give an approach which allows secure coprocessors to be integrated into existing operating systems; we continue with a machine-user authentication section, which tackles the problem of verifying the presence of a secure coprocessor to users. |

| | Geek.com Geek News - ClearSpeed follows through on high-throughput math coprocessor |
| | It's true that it would not work if you had to send data to the coprocessor an instruction at a time, but you could send a bit of code to compute matrix transformations, and thousands of matrices to transform, all at once, and then recieve the results all at once, some microseconds later. | | | The OS itself does not need to be recompiled, but a driver is probably needed in order for software to communicate with the ClearSpeed card. | | | It can't get it / put it from/to main memory because that would play havoc with main CPU(s) cache coherence and forcing the main CPU(s) to flush their L1/L2 caches to main memory and then wait for the coprocessor would obviously defeat the purpose. |
