Intel (C) C8231A: floating point arithmetic Co-processor to support Z80 CPU
◦ Co-processor manufacturer: AMD (AM9511) or Rochester Electronics replacement, licensed by Intel (c) 1980 (C8231A).
Rochester Electronics is licensed and authorized by semiconductor manufacturers to provide a continuing manufacturing source for mature/discontinued products.
AM9511 APU performs floating point calculations that would be too time-consuming or cumbersome if done on Z80. In addition to the four basic operations, the 9511 can implement transcendental functions (sin, log, etc.), and it can also perform conversion from floating point to fixed point and vice versa. It can also perform operations in 16 or 32 bit fixed point two's complement integer representation.
