Performant as a measure of speed against rival BASIC interpreters. BBC Basic is recognised as being one of the fastest floating point BASIC interpreters written for 8-bit CPUs. This was partly down to how the language was coded (in 6502 originally), and certain aspects of the BBC Micro's architecture. Although the BBC Micro's CPU was only running at 2Mhz, it had fast RAM chips with little to no contention, despite sharing memory with the video system. These benchmarks give some indication of relative speeds to its contemporaries. https://en.wikipedia.org/wiki/Rugg/Feldman_benchmarks I've run those benchmarks on the Z80 version. It is faster than the native BASIC of the Spectrum (Sinclair BASIC) running at the same CPU speed (3.5Mhz). https://github.com/breakintoprogram/next-bbc-basic/blob/main... |
