... The CPU has seven operating modes. Each operating mode has dedicated banked registers for fast exception handling. The processor has a total of 37 32-bit registers, including six sta- tus registers. DSP Subsystem The AT75C310 has two identical DSP subsystems. Each DSP subsystem is composed of: • An OakDSPCore running at 40 MIPS • ...

... Interrupt sources are programmed to be level sensitive or edge sensitive. External sources can be programmed to be positive- or negative-edge trig- gered, or low- or high-level sensitive. The AT75C310 has 23 programmable I/O lines. They can all be programmed as inputs or outputs. To optimize the use of available package pins, most of them are multiplexed with external signals of on-chip peripherals. ...

... OS Level The AT75C310 is supplied with a customized port of the Linux kernel. It features device driv- ers for all the on-chip peripherals, including the DSP subsystems, and supports virtual file system usage. It also supports the native TCP/IP facilities that have made Linux a success in Internet applications ...

... C-compilers, source level debuggers and hardware emulators. Packaging The AT75C310 is supplied in a 160-lead PQFP package. This provides the best compromise between external connectivity and cost. An alternative 240-lead PQFP package is also available. In addition to a larger I/O capability, it provides the application developer with the possibility of using advanced development tools for the DSP subsystem software ...
