Provided herein are semiconductor dies including multiple controllers for operating over an extended temperature range. In certain embodiments, a semiconductor die includes multiple circuit modules, a temperature sensor that generates a detected temperature signal, an interface that communicates with an external host, a primary controller coupled to the interface and operable to control the circuit modules, and a secondary controller coupled to the interface. In response to the detected temperature signal indicating that the temperature of the semiconductor die exceeds a threshold temperature, the primary controller enables the secondary controller, which in turn disables the primary controller and at least a portion of the plurality of circuit modules to reduce heat dissipation.

Semiconductor die including multiple controllers for operating over an extended temperature range

A digital processor and method of operation utilize an alias address space to implement variable length instruction encoding on a legacy processor. The method includes storing instructions of a code sequence in memory; generating instruction addresses of the code sequence; automatically switching between a first operating mode and a second operating mode in response to a transition in instruction addresses between a first address space and a second address space, wherein addresses in the first and second address spaces access a common memory space; in the first operating mode, accessing instructions in the first address space; in the second operating mode, accessing instructions in the second address space; and executing the accessed instructions of the code sequence. Instructions of different instruction lengths may be utilized in the first and second operating modes.
