1975 Jrnl. Physics G 1 801 The superscalar case resembles ordinary spinor theories more closely in that the mass enters linearly thanks to the auxiliary scalar field H.
1986 Proc. Royal Soc. A. 405 236 Since the state | Ω 〉 is ‘full’ and represents a scalar–isoscalar particle, the field generated from it is chiral and superscalar.
2006 Jrnl. Physics A 39 11661 The spontaneous breaking is carried by a superscalar field.
2. Computing. Designating a processor which can execute more than one instruction per clock cycle by using processing units operating in parallel; of or relating to such operation.

1988 Computer Archit. News June 71 Computer architects have been thinking of new ways to improve uniprocessor performance... Superscalar..and..vector processing try to improve performance by exploiting instruction-level parallelism.
1996 G. Bell in D. Steier & T. M. Mitchell Mind Matters vi. 210 The superscalar processors, containing 64 floating-point and 32 fixed-point registers of 64 bits, is designed for both scalar and vector operations.
2005 B. Parhami Computer Archit. xvi. 308 To go beyond this, we must rely on multiple instruction issue (superscalar design) and perhaps more advanced speculative execution.
