  • memory layout - In the 8088, what was the time cycles penalty for . . .
    Depending upon whether the prefetch unit was running ahead of or behind the execution unit (usually ahead on the 8086; usually behind on the 8088), use of an ES prefix may take either 1 or 4 cycles to the time required to execute code The biggest time penalty associated with using multiple segments was the need to reload ES a lot
  • What was the IBM PC cost saving for using the 8088 vs 8086?
    The 8088 has an 8-bit data bus whereas the 8086 has a 16-bit data bus, so the 8088 is a 16-bit chip for these purposes The IBM 5150 uses 64kx1 DRAM chips per its technical reference manual section 1-13 So when accessing anything in its 64kb of motherboard RAM, eight chips respond at once, each providing or receiving a single bit
  • How much did IBM save by limiting the PC to 4. 77 MHz?
    My understanding is the CPU clock speed on the Intel 8088 in the IBM PC was selected as 4 77 MHz to simplify the design of the system This despite the 8088 coming in two versions - 5 MHz and 8 MHz
  • How did 8088 86 PCs implement flood-fill before SSE and GPUs?
    Or just that 8088 was an afterthought, with 8086 with 16-bit bus being the primary target, although I assume misaligned rep movsw is total garbage there ) So if you have an 8-bit pattern, unless your memset is very small, it's probably best to mov ah, al shr cx, 1 (and jnc over a stosb) to set up for rep stosw
  • 8088 - Why does a 80C88 require a decoupling capacitor between its two . . .
    I've noticed that the 80C88 from Renesas (datasheet here) has what is for me a quite unusual recommendation for decoupling: Namely, it recommends the usual 100 nF capacitor between pins 20 (GND) an
  • BIOS interrupts vs Hardware interrupts - Retrocomputing Stack Exchange
    The original 8088 only defined exceptions for the first 5 interrupt vectors, for Divide Error, Single Step, NMI, Breakpoint, and Overflow respectively Interrupts vectors 5 through 31 were marked as reserved in Intel's 8086 Family User's Manual:
  • Comparing raw performance of the Z80 and the 6502
    A lot has been said on the internet about the 6502, at 1MHz, being roughly equivalent in performance to the Z80, at 4 MHz It is said the Z80 has a typical 4 clock ticks per instruction, while the
  • What is the simplest UNIX system with a MMU?
    Another example is the Unix-like QUNIX (later renamed QNX) which was released for the Intel 8088 in 1982 Wikipedia: “in the late 1990s QNX released a demo image that included the POSIX-compliant QNX 4 OS, a full graphical user interface, graphical text editor, TCP IP networking, web browser and web server that all fit on a bootable 1 44 MB floppy disk for the 386 PC ”
