Open Instruction Sets and Processor Implementations
34:01 - 43:17 (09:16)
The main difference in clock cycles between RISC and Sys instruction sets is that the latter takes 10 clock cycles per instruction while the former takes only two. Open instruction sets allow for open source implementations and open source processors for wider use.
Clips
The average number of clock cycles per instruction is determined by the number of clock cycles, the clock cycle time, and the average number of instructions.
34:01 - 35:52 (01:51)
Summary
The average number of clock cycles per instruction is determined by the number of clock cycles, the clock cycle time, and the average number of instructions. For Sys constructions, using one of those interpreters would result in 10 clock cycles per instruction, while the risk instructions could be two.

Risk instruction sets have been the conventional way to do instruction sets and they haven't changed much since the 1980s.
35:53 - 37:57 (02:04)
Summary
Risk instruction sets have been the conventional way to do instruction sets and they haven't changed much since the 1980s. Despite this, they remain dominant due to their small clock cycles per instruction.

The major difference between calculators and computers is that computers can make decisions while calculators cannot make decisions.
37:57 - 39:21 (01:23)
Summary
The major difference between calculators and computers is that computers can make decisions while calculators cannot make decisions. Also, calculators have memory functions that let users store and retrieve values, while computers have memory that stores instructions and data.

The creators of RISC-V saw a need for an open instruction set architecture, leading to the creation of RISC-V.
41:31 - 43:17 (01:46)
Summary
The creators of RISC-V saw a need for an open instruction set architecture, leading to the creation of RISC-V. These instruction sets are like C, but specifically designed for hardware translation.
