The VISC ISA enables developers to describe complex algorithms in just a fraction of the code size it would take with the standard RISC-V instruction set, RISC-V vector extensions, or other ISA like x86 and Arm. VISC hardware decompresses an entire algorithm and sequences execution o...
The instructions are all 16-bit versions of existing instructions from the architecture profile, so the cost is only 12 additional lines in the 16-bit instruction decompressor (if implemented) or 12 more lines in a combined 16/32-bit instruction decoder, mapping onto existing decodings. ...
The computer has a general register file of registers, a RISC instruction decoder, and a CISC instruction decoder. The RISC instruction decoder is exposed for execution of user-state programs in a RISC instruction set, being an instruction set having fixed-length instructions and a load/store/...
