+title: The Intel 8080 CPU
+date: 2016-04-30 14:00:00
+permalink: /blog/2016/04/30/
+---
+
+We'd like to introduce [PC8080](/modules/pc8080/), a new 8080-based machine emulator recently added to the
+PCjs Project.
+
+Our first [8080 Test Machine](/devices/pc8080/machine/test/) loads a copy of the
+[8080 Exerciser](https://web.archive.org/web/20151006085348/http://www.idb.me.uk/sunhillow/8080.html)
+(specifically, [8080EX1](/devices/pc8080/rom/test/8080EX1.MAC)) and intercepts the exerciser's CP/M console
+calls so that you can see its progress in the Control Panel window.  It's a "headless" test machine
+(no keyboard or display), so that's all you get.
+
+The good news: PC8080 passes all the 8080 Exerciser tests.  And it doesn't do it by using all sorts of weird
+"flags tables", which most other 8080 emulations seem to fall back on.
+
+Like all the other CPU emulations in the PCjs Project, PC8080 never "calculates" the flags unless/until they are
+actually required, which considerably speeds up arithmetic operations.
+
+Of particular note are the 8080's subtract,
+compare, and decrement operations, which actually perform addition, not subtraction, by using two's complement
+arithmetic in "stages": the first stage (inverting the source operand) occurs *before* the addition, while the second
+stage (incrementing the inverted operand) occurs *after* the addition.  And it appears to be the result of the *first*
+stage, not the second, that determines the state of the Auxiliary Carry flag (AF).
+
+The behavior of the Auxiliary Carry flag (AF) and the associated DAA instruction are probably the most significant
+(and least understood) *arithmetic* differences between the 8080 and all later x86-based CPUs.  Well, there's also
+the fact that the 8080 doesn't provide an Overflow flag (OF).  Internally however, PC8080 retains the ability to
+calculate overflow (since PC8080 was a fork of PCjs), which should be useful when we add Z80 support to PC8080.
+
+On a related note, [Ken Shirriff](http://www.righto.com/) has some fascinating blog posts on the 8085 that also
+provide clues as to how the 8080 likely operates:
+
+* [Inside the ALU of the 8085 microprocessor (January 2013)](http://www.righto.com/2013/01/inside-alu-of-8085-microprocessor.html)
+* [Silicon reverse engineering: The 8085's undocumented flags (February 2013)](http://www.righto.com/2013/02/looking-at-silicon-to-understanding.html)
+* [The 8085's register file reverse engineered (March 2013)](http://www.righto.com/2013/03/register-file-8085.html)
+* [Reverse-engineering the 8085's ALU and its hidden registers (July 2013)](http://www.righto.com/2013/07/reverse-engineering-8085s-alu-and-its.html)
+* [Reverse-engineering the flag circuits in the 8085 processor (July 2013)](http://www.righto.com/2013/07/reverse-engineering-flag-circuits-in.html)
+* [Reverse-engineering the 8085's decimal adjust circuitry (August 2013)](http://www.righto.com/2013/08/reverse-engineering-8085s-decimal.html)
+
+The idea is to make [PC8080](/modules/pc8080/) sufficiently configurable so that it will work with a variety of
+8080-based systems, including those with memory-mapped video displays (like
+[Space Invaders](/devices/pc8080/machine/invaders/)), as well as simpler terminal-based systems, like the CP/M-based
+systems of old.
+
+In fact, as soon as Space Invaders is working, my next planned adaptation is a DEC VT100 terminal emulator (itself
+an 8080-based machine) which can then be "wired up" to other PCjs machine simulations.  This will not be yet-another
+VT100-compatible emulation -- which, like 8080 emulators, has been done to death -- but rather a simulation
+of the original VT100 hardware, building on [Adam Mayer's](https://github.com/phooky) work
+[reverse-engineering the VT100](https://github.com/phooky/VT100-Hax).

+
+As hinted above, some newer Model 5150 machines with the **Oct 27, 1982** BIOS included IBM BASIC C1.10.  And
+some even *newer* 5150 machines had a BIOS with a "1982" copyright year instead of "1981", which also changed the checksum
+byte from 0x78 to 0x77.  However, the project includes only the original "1981" version, since the difference was trivial.
+
+In general, IBM BASIC ROM images are 32Kb and IBM BIOS ROM images are 8Kb, and together they provide 40Kb of contiguous
+read-only memory, with the BASIC ROM spanning physical addresses 0xF6000-0xFDFFF and the BIOS ROM spanning addresses
+0xFE000-0xFFFFF.
+
+However, starting with Model 5160 ROM images dated **Jan 10, 1986**, our ROM images are actually 64Kb images that
+span addresses 0xF0000-0xFFFFF and include IBM BASIC C1.10 at offset 0x6000 (physical address 0xF6000), so there's no
+need to load the BASIC ROM separately.  That trend continued with the IBM PC AT Model 5170, whose ROM images are also
+64Kb and all contain IBM BASIC C1.10.
+
+Apparently, even the first Model 5160 was socketed for two 32Kb ROMs, but it came with an 8Kb ROM in the first socket,
+so that ROM (containing the first 8Kb of IBM BASIC C1.10) appeared at multiple addresses: 0xF0000, 0xF2000, 0xF4000,
+and 0xF6000.  None of our Model 5160 machine configurations emulate that layout, but it could easily be done,
+by extracting the first 8Kb of IBM BASIC C1.10 into a separate image and explicitly mapping it at each of those four
+addresses.
+
+See this [diagram](http://www.minuszerodegrees.net/5160/misc/5160_memory_layout_of_bios_and_basic.jpg) for a more
+visual description of the Model 5160's ROM layout.

 The project also contains BIOS ROMs, along with more detailed information, for the following machines:

+8080 Test Machine
+---
+
+This is a test of [PC8080](/modules/pc8080/), a new 8080-based machine emulator being added to the
+PCjs Project.
+
+The test machine below loads a copy of the
+[8080 Exerciser](https://web.archive.org/web/20151006085348/http://www.idb.me.uk/sunhillow/8080.html)
+(specifically, [8080EX1](/devices/pc8080/rom/test/8080EX1.MAC)) and intercepts the exerciser's CP/M console
+calls so that you can see its progress in the Control Panel window.  This is a "headless" test machine
+(no keyboard or display), so that's all you get.
+
+The good news: PC8080 passes all the 8080 Exerciser tests.  And it doesn't do it by using all sorts of weird
+"flags tables", which most other 8080 emulations seem to fall back on.
+
+Like all the other CPU emulations in the PCjs Project, PC8080 never "calculates" the flags unless/until they are
+actually required, which considerably speeds up all arithmetic operations.
+
+Of particular note are the 8080's subtract,
+compare, and decrement operations, which actually perform addition, not subtraction, by using two's complement
+arithmetic in "stages": the first stage (inverting the source operand) occurs *before* the addition, and the second
+stage (incrementing the inverted operand) occurs *after* the addition.  And it appears to be the result of the *first*
+stage, not the second, that determines the state of the Auxiliary Carry flag (AF).
+
+At 2Mhz, the 8080 Exerciser tests take quite a while, but you can click the speed button while the machine is running
+to increase the simulated speed; it will revert to 2Mhz when you exceed the maximum speed that your system supports.
+
+NOTE: The original [8080 Exerciser website](http://www.idb.me.uk/sunhillow/8080.html) is currently unavailable,
+so we refer you to the copy on
+[archive.org](https://web.archive.org/web/20151006085348/http://www.idb.me.uk/sunhillow/8080.html).
+The 8080 Exerciser source code has also been "forked" on [GitHub](https://github.com/begoon/8080ex1).
