Microprocessor with random number generator and instruction for storing random data

A microprocessor for running a multitasking operating system, the microprocessor being coupled to a system memory, the microprocessor comprising:

• a random number generator (RNG), having a buffer for accumulating between zero and N inclusive bytes of random data, wherein N is greater than one, and a counter for maintaining a count of said bytes accumulated in said buffer;
• and
• an instruction translator, coupled to said RNG, for translating an instruction instructing the microprocessor to store said bytes accumulated in said buffer to the system memory.

A microprocessor for running a multitasking operating system, the microprocessor having a plurality of user-visible registers, the microprocessor comprising:

• a random number generator (RNG), having a buffer for accumulating between zero and N inclusive bytes of random data, wherein N is greater than one, and a counter for keeping a count of said bytes accumulated in said buffer;
• and
• an instruction translator, coupled to said RNG, for translating an instruction instructing the microprocessor to store said bytes accumulated in said buffer to one of the plurality of user-visible registers.

A microprocessor, having a plurality of user-visible registers, comprising:

• a random number generator (RNG), for generating bytes of random data;
• and
• an instruction translator, coupled to said RNG, for translating an instruction of the microprocessor instruction set, said instruction comprising an opcode and a destination operand for use in specifying a destination for storing a number of said bytes of random data generated by said RNG, wherein said number is specified in one of the plurality of user-visible registers comprised in the microprocessor.
