# NAME

`tcx` —
Sun accelerated 8/24-bit color frame buffer

# SYNOPSIS

`tcx* at sbus? slot ? offset ?`

# DESCRIPTION

The `tcx` is a memory based color frame buffer, with graphics acceleration and overlay capabilities. Its control registers, colour lookup table and pixel memory can be mapped into a user process address space by using the mmap(2) system call. The `tcx` driver supports the minimal ioctl's needed to run Xorg(1), and can be operated in sparc/cgthree(4) emulation mode.
